Fixed bugs.

  • 4.4.104: can't calculate processes without PDF (native model particles as beams)
  • 4.4.103: a bug for the decay simulation (any decay gives e→m,M after diagram squaring)
  • 4.4.102: wrong work of the CompHEP random number generator at 64x machines
  • 4.4.98: working with new option for parallel calculations
  • 4.4.97: CompHEP generates wrong symbolic code for several processes
  • 4.4.97: Undefined symbols in the no-LHAPDF mode
  • 4.4.93: The options -add and -proc of don't work together properly.
  • 4.4.92: n_comphep can't read the QCD Scale expression.
  • 4.4.92: n_comphep writes down redundant information from session.dat to prt.
  • 4.4.91: Three bugs in generation of session.dat with s_comphep
  • 4.4.91: Wrong values of some commands in tag of the event default file format.
  • 4.4.91: Absence of clean-up of the program sceen if the width scheme has been changed.
  • 4.4.91: Unproper detection of libisajet in CERNLIB if there is a shared version of the libary.
  • 4.4.90: Several bugs in generation of session.dat with s_comphep
  • 4.4.90: Wrong values of some commands in tag of the event default file format.


  • Symbolic part:
    • 4.4.103: make output (during compilation/linking) is kept in make_gui.log
    • 4.4.103: restored editting of composite particle when final state is entered
    • 4.4.98: a new option for parallel calculations in
    • 4.4.90: All PDFs in the beam/strfun tables have prefix PDF (or LHA, if LHAPDF is interfaced)
    • 4.4.90: Proper generation of session.dat in s_comphep.
    • 4.4.90: Lots of internal re-arrangements (to simplify the program structure).
  • Numerical part:
    • 4.4.99: SUSY models: CERNLIB/ISAJET dependence removed, SLHA interface and SUSPECT added
    • 4.4.96: CompHEP-ROOT interface, for histogramming only
    • 4.4.96: a new version
    • 4.4.96: diagram viewer is opened in a separate window
    • 4.4.96: HepML information is added to event files in LHAef
    • 4.4.90: A new improved version of
    • 4.4.90: Diagram viewing is available in n_comphep (a new option in the main menu)
    • 4.4.90: More convinuent behavior of the menu 'Kinematics'
    • 4.4.90: Re-arranged menu “Initial State”. Beam particle and PDF are separated.
    • 4.4.90: The LHA event file format has been added, still with no extra HepML tags.
  • Common:
    • 4.4.98: lots of internal changes
    • 4.4.96: several improvements in the CompHEP internal structure
    • 4.4.93: CompHEP has been tested on Mac OX 10.4 and should work on Mac OS 10.4.X and later.
    • 4.4.90: Now CompHEP is compatible with gcc-4.x
    • 4.4.90: A new version of make_tab. Now it can processes files with several subprocesses.
    • 4.4.90: CompHEP can be compiled in two different modes: with OR without LHAPDF.
    • 4.4.90: Several options in ./configure have been added: –with-gcc4, –with-lhapdf, –debug, –help
  • Documentation
    • 4.4.91: Updated NUM_BATCH-HOWTO
    • 4.4.91: Updated LHAPDF_in_CompHEP-HOWTO
    • 4.4.91: Updated INSTALL
    • 4.4.90: New NUM_BATCH-HOWTO
    • 4.4.90: LHAPDF_in_CompHEP-HOWTO


  • 4.4.90: A new format of the initial state in session.dat.
  • 4.4.90: ComHEP has two regimes of compilation, with or without LHAPDF. CompHEP with LHAPDF has incompatible beam strfun tables. So, these tables will be empty if a user tries to use old files in the new version. No problems in ComHEP without LHAPDf.


  • Mixing of several event files in LHAef.
  • A new version of mk_tab compatible with the LHAEF format.
  • Check LHAPDF-compatible session.dat in internal-PDF-compatible n_comphep (and vice versa).
  • Help files for the new “Initial state” menu.
  • More convinuent behavior of the menu 'Initial state'. Initialization not by [Esc], but by a new menu command (Init).
