MATRIX version 2

NEW MATRIX_v2.1.0.beta2.tar.gz
Version 2.1.0.beta2 (Jul 2022)
  • fixed bug in local runs/result combination due to decoding in python2
  • fixed problem in runtime extrapolation for power corrections
  • added transverse mass cut to off-shell charged-current Drell-Yan
  • added extra lepton rapidity cuts for neutral-current Drell-Yan
MATRIX_v2.1.0.beta1.tar.gz
Version 2.1.0.beta1 (Mar 2022)
  • added triphoton (ppaaa03) and top-quark pair (ppttx20) production
  • included linear power corrections through recoil (switch in input)
  • included bin-wise extrapolation of rcut (switch in input)
  • included TSV scale variation (needed for last two features; will replace CV scale variation in future)
  • added double-differential distributions (dddistribution.dat), not working with TSV (yet)
  • Python 3 compatibility added (not fully tested in all parts of the code)
MATRIX_v2.0.1.tar.gz
Version 2.0.1 (Feb 2022)
  • fixed bug in photon recombination that affected leptons with a rapidity above 3
MATRIX_v2.0.0.tar.gz
Version 2.0.0 (Jun 2021)
  • First MATRIX version 2 release.
  • added NLO EW corrections for DY and and massive diboson processes
  • added NLO gg corrections for ZZ and WW processes
  • new inputs for NLO EW, NLO gg (switches, photon recombination, ...)
  • 2 approximations implemented for CKM treatment in EW corrections to DY
  • various matching schemes of EW and QCD corrections implemented
  • using only additive matching when LO vanishes
  • new syntax for directly adding fiducial cuts in parameter.dat
  • implemented option to enhance statistics in tail of distributions
  • restructured large parts of C++ code
  • improved generation of integration grids and fixed remaining inefficiencies
  • restructured some parts of phython scripts (result combination, result output, ...)
  • added possibility to run on local scratch of the nodes on a cluster
  • some bug fixes
  • supplementary manual describes features of MATRIX version 2 (with reference results)
