THEORY

New scheme of work with initial beams and final composite particles was changed.

If you have a private model and want to use them with CompHEP-4.4.0, you have to copy cpart1.mdl file to cpartN.mdl file where N is a number of your model by commands:

cd path_to_user_working_directory/model
cp cpart1.mdl cpartN.mdl

All new composite particles must be introduce into table by using edit model facilities.

• Compilation bug when CERN libraries do not available
• Make randomization of momenta of 2 last particles in event file.
• QCD lambda are taken from PDF now.

• SYMB_BATCH-HOWTO
• NUM_BATCH-HOWTO
• Help for beam table (s_beam_1.txt)
• Help for structure function table (s_strfn_1.txt)

• Symbolic part
  • Add table for initial beam (proton, anti-proton, …)
  • Introduce switch F3 from beams to particles and vs.
  • Change composite particle table (see [1])
  • Introduce switch F3 from composite particles to particles and vs.
  • Symbolic conservation law is off by default.
  • LOCK file is restored.
  • Maximum sum of output and input particles (MAXINOUT) is 10 by default.

• Numerical part
  • re-arrange menu “Width scheme”
  • Change “Equiv.Photon(…)” to WWA

• Common
  • Re-arrangement of usage of messages and warnings.

• All CompHEP libraries were collected into lib subdirectory
• CompHEP PDF file standard description move to tbl-pdf directory
• Files drandXX.[ch] move to service2 subdirectory
