Interface between ISAJET SUSY RGEs subroutine "SUGRA", PYTHIA,
PDFLIB and PROSPINO:
-
Input values for SUSY parameters at Unification scale
-
"SUGRA" calculates SUSY masses and couplings evolutions downto
EW scale
-
PYFRIS feeds the results into PYTHIA at EW scale
-
PYTHIA diagonalizes mass matrices, calculates BRs and LO
cross sections
-
this LO cross sections are done with the CTEQ5L from PDFLIB
-
finally PROSPINO also picks some PDFs from the PDFLIB, the
squark, gluino and top mass,
plus
stop mass and mixing at the EW scale and calculates the LO and NLO cross
section, which allows to
determine the K-factor=sigma(NLO)/sigma(LO) that one can use to correct
the Pythia LO cross section
-
SUSY models currently available: mSUGRA, mGMSB, mAMSB
-
Programming Language: Fortran 77
-
Used to study SUSY models at D0 to determine SUYSY signal
properties and to interpret analyses limits
-
Current D0 version: "v1.1" (July 2001)
