NMSSMTools
TOOLS FOR THE CALCULATION OF THE
HIGGS AND SPARTICLE SPECTRUM IN THE NMSSM:
NMHDECAY, NMSPEC, NMGMSB and NMHDECAY_CPV
NMHDECAY
The Fortran code NMHDECAY [1,2] computes the masses, couplings and decay
widths of all Higgs bosons as well as the masses of all
sparticles of the NMSSM in terms of its parameters at the electroweak or susy
breaking scale. The computation of the Higgs spectrum includes
leading electroweak corrections, two loop terms and propagator
corrections as in [3]. (We are grateful to P. Slavich for providing the
corresponding routines.)
The computation of the decay widths is carried out as in
HDECAY [4].
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. LHC
constraints on the couplings of the observed Higgs boson with
mass ~125 GeV are checked.
B and K physics constraints are included as in
ref. [5] 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 package [6].
Constraints on dark matter direct detection (both spin dependent and spin independent)
are also checked.
SLHA
conventions [13] for input and output are used. NMHDECAY is included in the
NMSSMTools package that can be downloaded below.
Sample input and output files are included.

NMSPEC
The Fortran code NMSPEC [7] proceeds like NMHDECAY, but with soft Susy
breaking terms specified at the GUT scale.
The soft Susy breaking terms at the GUT scale can be chosen as
nonuniversal, if desired. SLHA
conventions [13] for input and output are used. NMSPEC is included in the
NMSSMTools package that can be downloaded below.

NMGMSB
The Fortran code NMGMSB allows for gauge mediated
supersymmetry breaking terms, including couplings of the
singlet to messengers. The user can either assume general
boundary conditions at the messenger scale, as described in
[8], or boundary conditions at the GUT scale following [9].

NMSDECAY
The Fortran code NMSDECAY [11] allows to compute sparticle widths and branching ratios.
It is based on a generalization of SDECAY [12], including
the corresponding QCD corrections and 3body decay modes. Slepton 3body
decays, possibly relevant in case of a singlinolike LSP, have been
added. Decays to gravitinos are included for GMSB models. The output follows
SLHA
conventions [13]. NMSDECAY is included in the
NMSSMTools package that can be downloaded below.

NMSSMTools
NMSSMTools contains NMHDECAY, NMSPEC, NMGMSB, NMHDECAY_CPV and NMSDECAY.

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 script file "run" and the directories
"sources", "main" and "microRun", 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.
Executable routines are created in the directory
"main".
If a subroutine in the directory "sources" is modified, one has to
type "make init" and "make" again. If a routine in the directory "main"
is 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 [13]).
For more details see the description in README .

21.07.2013: version 4.1.0
 constraints on a SMlike 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 nonZ_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
CPodd and charged Higgs masses from chargino/neutralino loops have been
added for "Higgs precision = 0".
 Chargino/neutralino 1loop corrections to
the CPeven 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. neutralinoneutralino > 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

 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 (g2)_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 (2007) 090,
arXiv:0710.3714 [hepph]; 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 nonuniversal
soft parameters at the GUT scale
