资源说明：Official micrOMEGAs code starting at version 2.4.1
The file content of the code is described in the file fileMap.txt
! We use 'gmake' options in our Makefiles. If you do not have 'gmake'
! then more likely your 'make' is identical to 'gmake'.
I. General installation.
Launch
[g]make
It should generate files with compilers flags
CalcHEP_src/FlagsForMake
CalcHEP_src/FlagsForSh
and compile
CalcHEP_src/bin/s_calchep
lib/micromegas.a
Possible problems are discussed in Section VII below.
micromegas_4.3 was tested for Linux, and Darwin
II. To work with MSSM, NMSSM, CPVMSSM, UMSSM, IDM, LHM, Z3IDM, Z4IDSM models
go to the corresponding directory.
To generate an executable use
[g]make main= is expected to be a C (.c) file, C++ (.cpp) one,
or a Fortran (.F) file.
The list of functions you can use in your programs are described in man/man.pdf as well as
hep-ph/0405253, hep-ph/0607059, arXiv:0803.2360[hep-ph], arXiv:1005.4133[hep-ph] and arXiv:1305.0237[hep-ph].
*** For Cygwin, launch an executable with
../cgwRun
III. Each model directory contains at least 2 sample files:
main.c
main.F
a sample for C++ can be obtained by 'cp main.c main.cpp'
main.c and main.F contain several independent modules
which can be switched ON by '#define' preprocessor instructions
at the top of the file.
The modules are:
a) MASSES_INFO
displays mass spectrum for odd particles (super partners) and
Higgs particles as well as Higgs widths;
b) CONSTRAINTS
checks experimental constraints;
c) HIGGSBOUNDS
calls HiggsBounds and HiggsSignal to constrain the Higgs sector;
d) LILITH
calls LiLith to constrain the Higgs sector;
e) SModelS
calls SModelS to constrain the new physics sector;
f) OMEGA
computes the relic density;
g) INDIRECT_DETECTION
calculates the WIMP annihilation spectra and integrates
over the halo profile;
h) LOOP_GAMMA
calculates the two-photon spectrum from annihilation of two neutrinos
into two-photons and Z-photon;
i) RESET_FORMFACTORS
resets parameters of nucleon form factors, DM velocity
distribution, and nucleus Fermi density;
j) CDM_NUCLEON
calculates WIMP-nucleon elastic scattering amplitudes and cross-sections;
k) CDM_NUCLEUS
calculates the number of events for 1day&1kg of detector material and
recoil energy distribution for WIMP-nuclei interactions;
l) NEUTRINO
computes the neutrino flux from DM captured in the Sun/Earth and
the corresponding muon flux;
m) DECAYS
computes the decay widths and branching ratios for any particle;
n) CROSS_SECTIONS
calculates cross sections for any 2->2 process and some 2->3 processes
o) SHOWPLOTS
displays plots on the screen
p) CLEAN
cleans intermediate files
IV. Each model directory contains a subdirectory 'calchep/' intended
for calculation of different cross sections and decay widths
in interactive sessions for SM and other models.
V.To implement a new model, launch
./newProject
Then the directory will be created with all needed subdirectories
and sample files inside. Next you need to put the new model files in the
work/models directory. Further instructions can be found in the local
README file.
VI. To clean all generated files use
[g]make clean
or
./clean
launched from micromegas_3.X directory. In each model directory you
can call
[g]make clean
to remove all generated files in this particular directory.
VII. Compilers and their Flags
Options for compilation are stored in the file
CalcHEP_src/FlagsForSh
If this files does not exist, it is generated by [g]make according
to Unix version. If CalcHEP_src/FlagsForSh exists, [g]make
only checks it. In case of problem with compilers and their flags
one can improve CalcHEP_src/FlagsForSh and launch [g]make again.
Using
[g]make clean
you will be asked about an option to save FlagsForSh for the next
compilation.
[g]make flags
only generates FlagsForSh file. It gives you an option to
select the compiler and flags you prefer.
Special requirements, but not strictly necessary.
1) To see graphical plots generated by micrOMEGAS and work with CalcHEP
graphical interface, X11 development package should be installed.
One can check that directory /usr/include/X11 contains *.h files.
If not, CalcHEP will be compiled in 'blind' mode and
CalcHEP/FlagsForSh will contain empty definition of LX11 variable.
LX11=""
The name of package which has to be installed to solve the problem
depends on platform
libX11-devel for Fedora/Scientific, Darwin(MAC)
libX11-dev for Ubuntu/Debian
xorg-x11-devel for SUSE
2) CalcHEP interactive section needs 'xterm' command.
