We present models of particle interaction  based on Minimal 
Supersymmetry extension  of the Standard Model. We present MSSM
with SUSY scale input, MSSM with GUT scale input and version of model
which reads external SLHA file. 

Read file INSTALLATION for model installation and 
     file CITE for  references on scientific publications which 
     present realization of the model.

By default  SuSpect package for MSSM spectrum calculation is used.  Interface with 
SuSpect is realized in terms of Susy Les Houches Accord (SLHA). All SLHA 
instructions are presented explicitly in models/func*.mdl files. In the
same files one can find 'System' call of suspect.exe. One can replace here
SuSpect on other spectrum generator.  For example, one can replace line 

sys |System("PATH_TO_SUSPECT/suspect.exe") 

on 

sys |System("PATH_TO_SOFTSUSY/softpoint.x leshouches <suspect2_lha.in >suspect2_lha.out")

or 

sys |System("PATH_TO_SPHENO/SPheno") 

In the last case file names "suspect2_lha.in" and "suspect2_lha.out"  used in
func*.mdl  have to be replaced  on "LesHouches.in" and "SPheno.spc" correspondingly. 
Note that SLHAPlus packhage allows to realize all read/write instruction 
directly in the model files (func*.mdl). These instructions can be easyly 
modified  if it needs. 

To have agreement between spectrum  calculated by SuSpect   and
Lagrangian we  use external code for effective lambda couplings "lib/lambdas.c"  
based on paper M.Carena et al, Nucl.Phys. B461 (1996) 407-436. The code was extracted
from the Hdecay program. Indeed lambda1, lambda3, lambda6 are calculated by this code, 
but lambda2, lambda4,lambda5,lambda7 are defined using Higgs masses
calculated by SuSpect. 
 
Directory models contains 8 versions of MSSM model. Models numerated by even
numbers 2,4,6,8  are obtained from 1,3,5,7 by adding Higgs->GG and Higgs->AA
effective vertexes. 
Models 1,2  present MSSM with low (SUSY) scale input. 
Models 3,4  present MSSM with SUGRA(GUT) scale input.
Models 5,6  present MSSM with slha file input. The input file "slha.out"
should be disposed in CalcHEP working directory. 
Models 7,8  present MSSM with SUSY scale input and  tree-level spectrum 
which is calculated using  effective Lambdas. 
  
LanHEP source files for models are stored in directory lanhep. 
The main file  is startup.lhp. Key word 'scenario' 
%      EWSB  - slha  EWSB for calchep,
%      SUGRA - slha SUGRA for calchep,
%      SLHA  - slha input for calchep,
%      Tree   
defines input. Switch hgg=On/Off defines generation of  hGG/hAA vertexes.
