NMSSMTools

TOOLS FOR THE CALCULATION OF THE


HIGGS AND SPARTICLE SPECTRUM IN THE NMSSM:


NMHDECAY, NMSPEC and NMGMSB





NMHDECAY
The Fortran code NMHDECAY computes the masses, couplings and decay widths of all Higgs bosons of the NMSSM, and the masses of all sparticles, in terms of its parameters at the electroweak (or susy breaking) scale: the Yukawa couplings lambda and kappa, the soft trilinear terms A_lambda and A_kappa, and tan(beta) and mu_eff = lambda*S. (Instead of A_lambda, the MSSM-like parameter M_A can also be used as input.) The computation of the Higgs spectrum includes leading electroweak corrections, two loop terms and propagator corrections. The computation of the decay widths is carried out as in HDECAY, but momentarily without three body decays. Each point in parameter space is checked against negative Higgs boson searches at LEP, and negative sparticle searches at LEP and the Tevatron, including unconventional channels relevant for the NMSSM. B physics constraints from b -> s gamma, Delta M_q, B -> mu+mu- and B+ -> tau+ nu_tau are included as in ref. [4] below and updated occasionally. The dark matter relic density, direct and indirect detection cross sections can be computed via a link to a NMSSM version of the MicrOMEGAs code [3]. SLHA conventions for input and output are used. NMHDECAY is part of the NMSSMTools package that can be downloaded below.

NMSPEC
NMSPEC allows to compute the sparticle and Higgs masses, Higgs decay widths and couplings in the NMSSM, with soft Susy breaking terms specified at the GUT scale. Exceptions are the soft singlet mass and kappa, that are both determined in terms of the other parameters through the minimization equations of the Higgs potential. The soft Higgs and gaugino masses at the GUT scale can be chosen as non-universal, if desired. NMSPEC is included in the NMSSMTools package below.

NMGMSB
NMGMSB allows to compute the sparticle and Higgs masses, Higgs decay widths and couplings in the NMSSM, where soft Susy breaking terms are specified at by gauge mediated supersymmetry breaking, plus terms originating from couplings of the Singlet to messengers. The boundary conditions at the messenger scale are taken from the paper below, and described in the file README. Either the soft Singlet mass or a Susy tadpole term XIS are determined in terms of the other parameters through the minimization equations of the Higgs potential. Sample input- and output files are included. It is part of the NMSSMTools package described below.

NMSDECAY
NMSDECAY allows to compute sparticle widths and branching ratios (not yet for NMGMSB). It is based on a generalization of SDECAY, including the corresponding QCD corrections and 3-body decay modes. Slepton 3-body decays, possibly relevant in case of a singlino-like LSP, have been added.

    HOW TO USE NMSSMTOOLS: README (plain text)
    Directory NMSSMTools_4.9.2 (gzipped and tared), contains NMHDECAY, NMSDECAY, NMSPEC, NMGMSB, micromegas_3.3, EXPCON for experimental constraints, and sample input- and output files.

How to use NMSSMTools:

  • After the download of NMSSMTools_x.tgz (where x is the version number), type "tar zxvf NMSSMTools_x.tgz". This will create a directory named NMSSMTools_x. Go into this directory. There you find the directories
  • "sources", "main" and "micromegas", which contain source files;
  • "EXPCON", which contains data files corresponding to experimental constraints;
  • "SAMPLES", which contains sample input and output files;

    COMPILATION:

    To compile, type first "make init", then "make". A first compilation may take a while, since most subroutines of micromegas are compiled. The following eight executable routines are created in the directory "main": nmhdecay, nmhdecay_rand, nmhdecay_grid, nmspec, nmspec_rand, nmspec_grid, nmgmsb and nmgmsb_rand. If a subroutine in the directory "sources" was modified, one has to type "make init" and "make" again. If a routine in the directory "main" was modified, it suffices to type "make" again. To delete all the already compiled codes type "make clean".

    INPUT FILES:

    From the version 2.0.0 onwards, the task to be performed by an input file is independent from its name. Any name is allowed, provided it contains the three letters "inp"; it can be of the general form PREFIXinpSUFFIX where PREFIX and SUFFIX can contain dots etc..

    The input file can be located in any directory specified by a PATH.

    To run any input file PREFIXinpSUFFIX, type "run PATH/PREFIXinpSUFFIX". (PATH is optional; if absent, the input file has to be located in the same directory as the script file "run".)

    The output files are located in the directory specified by PATH. They have the following format:
    If one single point in the parameter space is evaluated:
      PREFIXspectrSUFFIX (includes the previous PREFIXdecaySUFFIX), PREFIXomegaSUFFIX (if the relic density is computed)
    If scans are performed:
      PREFIXerrSUFFIX as well as PREFIXoutSUFFIX
    However, the task to be performed by an input file must be specified in the BLOCK MODSEL at the beginning (see the SLHA2 conventions in B. Allanach et al., SUSY Les Houches Accord 2, Comp.Phys.Commun.180:8-25,2009, arXiv:0801.0045.

    For more details see the description in README .

      - constraints on a SM-like Higgs mass (125.7 \pm 3 GeV) and its signal rates (from arXiv 1306.2941 ) added; modifiable in the subroutine Higgs_CHI2 at the end of sources/lhchig.f.
      - guess for the initial values of the parameters in nmspec_rand.f corrected; with thanks to Jiang Yun.
  • 23.05.2013: version 4.0.0
      - The general NMSSM with non-Z_3 invariant parameters either at the (low) SUSY scale or at the (high) GUT scale is made possible, as well as the nMSSM with kappa=0. (See README for the allowed options; now most parameters not given in input files are assumed to be = 0).
      - NMSSM specific radiative corrections to CP-odd and charged Higgs masses from chargino/neutralino loops have been added for "Higgs precision = 0".
      - Chargino/neutralino 1-loop corrections to the CP-even Higgs masses use parameters at the scale QSTSB (resumming some large logarithms), and some NMSSM specific large logarithms have been added for "Higgs precision = 0".
      - The relic density and the direct detection cross sections are computed with the new version micromegas 3.0 (as of May 2013), which includes virtual contributions to neutralino annihilation cross sections (e.g. neutralino-neutralino -> WW) and loop contributions to neutralino+neutralino -> gamma+gamma. (Hence a first compilation of the code and a calculation of the relic density takes longer than before. In relden.F, virtual decays can be switched off setting setVVdecay(0) instead of the default setVVdecay(1).)
      - The direct detection cross section is computed in terms of sigma_PiN and sigma_S instead of sigma_PiN and sigma_0; now sigma_PiN and sigma_S can be specified in init.f.
      - The exp. constraint on dark matter relic density is now 0.1187 +/- 0.0017 (arXiv:1303.5076), but one has to allow for theoretical errors which are difficult to estimate. The default window in init.f is 0.1187 +/- 0.0085, but can be modified by the user.
      - New interface between NMSSMTools and\A0 micromegas 3.0 using the full Higgs effective lagrangian with parameters computed at the same precision level as for Higgs masses and couplings. These parameters can be found in the\A0BLOCK EFFECTIVE_COUPLINGS at the end of the output file #spectr#.
      - With "Higgs precision = 1 or 2", the relic density and the direct detection cross sections are computed by micromegas with the correct Higgs masses (previously micromegas used always the Higgs masses as computed with "Higgs precision = 0").
      - The diagonal chargino loop contributions to H/A->Z+gamma are included (with thanks to Peiwen Wu for discussions).
  • 30.01.2013: version 3.2.4
      - Factor 2 in the charged Higgs loop contribution to H->gammagamma and H->Zgamma corrected (with thanks to Peiwen Wu, L. Sluter and P. Richardson; impact on the partial widths <2% for a charged Higgs mass >~ 300 GeV)

      - NMSDECAY: a warning appears on the screen, of QCD corrections to colored sparticle decay widths are negative and larger than the tree level widths. Then the relative corrections "corr", leading to a negative width when added according to (1+corr), are replaced by 1/(1-corr).

      - the BLOCKs for parameters at the GUT-scale in the SLHA-output of NMHDECAY and NMSPEC are renamed

  • 10.12.2008: Release of version 2.1.0
      - Significances for the detection of all neutral Higgs bosons at the LHC (at low luminosity, 30 fb-1, and at high luminosity, 300 fb-1) can be computed, following U. Ellwanger, J.F. Gunion and C. Hugonie, JHEP {0507} (2005) 041, arXiv:hep-ph/0503203, and G. Belanger, C. Hugonie and A. Pukhov, arXiv:0811.3224 [hep-ph].
      - New version of micrOMEGAS (2.2) included, which allows to compute the LSP annihilation cross section, the resulting photon spectrum for indirect detection and spin dependent/spin independent LSP-nucleon cross sections for direct detection, following G. Belanger, F. Boudjema, A. Pukhov and A. Semenov, arXiv:0803.2360 [hep-ph], and G. Belanger, C. Hugonie and A. Pukhov, arXiv:0811.3224 [hep-ph].
      - Constraints from radiative Upsilon decays and the eta_b mass measurement are implemented as in F. Domingo, U. Ellwanger, E. Fullana, C. Hugonie and M.A. Sanchis-Lozano, arXiv:0810.4736 [hep-ph].

      - Warnings in case of inappropriate input files modified
  • 13.05.2008: Release of version 2.0.0
      - The architecture of the code has been modified: From the version 2.0.0 onwards, the task to be performed by an input file is independent from its name. However, the task to be performed by an input file must be specified in the BLOCK MODSEL at the beginning, see the new description README.
      - The routines NMGMSB have been added, which allow for boundary conditions specified by gauge mediated supersymmetry breaking (see above).
      - SM error bars for the muon anomalous magnetic moment have been updated. Still: the SM hadronic contribution to (g-2)_muon is estimated from e+e- data only, data from tau decays is ignored; consequently the exp. BNL result differs from the SM by ~3 sigma. If the line "CALL MAGNMU(PAR,PROB)" is present in the main routines, it is checked whether a point in parameter space differs by at most by 2 sigma from the exp. result. Hence, points in parameter space for which the Susy contribuion is too small (or vanishing or of the wrong sign) generate warnings or are considered as phenomenologically excluded. If this constraint is considered as too strong by the user it is enough to comment the line "CALL MAGNMU(PAR,PROB)" in the main program.
      - Exp. constraints from the Tevatron on sbottoms updated.
  • 17.03.2008: Release of version 1.3.0
      - The muon anomalous magnetic moment is computed (to two loops) according to F. Domingo and U. Ellwanger, JHEP 0712:090 (2007), arXiv:0710.3714 [hep-ph]; a warning is issued if the susy contribution incl. theoret. errors is less than ~10^{-9} or larger than ~5*10^{-9}
      - The input of the soft parameters of the first two generations is simplified for the versions nmhdecay
      - The versions nmspec_grid and _rand allow to scan over non-universal soft parameters at the GUT scale
      - A script "run" is added which allows to run user-defined input files
