ISAWIG BUGS
The current version of ISAWIG of 1.200 of 24/09/02. There were no bugs
fixed in this version, however several changes were made in order to allow the
use of different versions of ISAJET and HDECAY.
The previous version of ISAWIG is 1.105 of 10/04/02. In this version a number of minor bugs were fixed, mainly in the RPV code. Thanks to Peter Skands for finding many of these
- The decay mode top to charged Higgs bottom was incorrectly given the matrix element code 100.
- The decay heavy sbottom to antineutrino down used the wrong mixing matrix element.
- The decays of the sbottom to neutrino down used the mixing matrix elements rather than the squares.
- The decay heavy sbottom to lepton up used the wrong mixing matrix element.
- In the LQD decays of the gluino one of the virtual masses used to
remove diagrams was incorrect.
- In the decay of the neutralinos and gluinos to neutrino down antidown the mass
of the virtual right down squark was incorrect in the absence of mixing.
- Incorrect squark masses were used for the virtual particles in the decay chargino
to three down type quarks.
- In the decay gluino to lepton up antidown the wrong squark masses were used when
the squarks could mix.

The previous version 1.104 of 02/07/01. This included a modification to allow the
use of pion chargino decay modes for AMSB models.

The previous version 1.103 of 22/04/00. This included a correction of the sign
convention of the chargino mixing matrices and the stop, sbottom and stau mixing
angles, thanks to Brian Harris.
The problem was in our conversion between the conventions of ISAJET and Haber and Kane.
A summary of our conventions and the conversion can be found
here.

The previous version 1.102 of 9/01/00. This includes a minor fix in the ISAWIG
subroutine to remove a second declaration of the variable MT which was defined twice.All the files as a gzipped tar file.
The previous version 1.101 of 17/01/00. This includes changes due to new version
of ISAJET 7.48. This means there are changes to the SSRUN and
SUGRUN programs, although not to the main ISAWIG code. All the files as a gzipped tar file.
The original version 1.100 of 14/12/99 can be found below.
The old code and DATA files which work with ISAJET7.42 can be found here. All the files as a gzipped tar file.
