The HERBVI package is a set of routines which when linked with the
Monte Carlo event generator allows the simulation of lepton and
baryon number violating standard model processes at hadron
The physics simulated is described in Z.Phys. C66 (1995) 285-302 and the
manual describes how this is implemented.
If you use HERBVI please refer to it as something along the lines of
HERBVI M. J. Gibbs and B. R. Webber, Comput.Phys.Commun. 90 (1995) 369-380
The code of HERBVI is available in the following pieces
To run HERBVI you will need to link with the latest version
The code is designed to work with HERWIG6.4
We have had problems running HERBVI under linux and are therefore recommending
the -fno-automatic option with g77 and the relevant static option with other
The following modifications will need to be made to HERWIG.
A version of the include files with the above modifications are
available HERWIG64.INC and
- The dummy subroutines HVCBVI and HVHBVI will
need to be deleted from the HERWIG code.
- The variable NMXHEP in the HERWIG include
file which is the maximum number of entries in the event
record must be increased. A value of 15000 should be sufficient.
- The variable MODMAX in the HERWIG include
file which is the maximum number gauge bosons in an event
must be increased. A value of 200 should be sufficient.
This code is not actively maintained. I will check when a new
version of HERWIG is released that HERBVI will run
with it. However as Mark Gibbs has left physics it is unlikely
there will be any other changes.
HERBVI was written by Mark Gibbs. Peter Richardson is currently
responsible for maintaining the code.
I am not aware of anyone who is actually using this package. If you
are please let me
