Changelog

2016-10-07 Cristian Baldenegro [email protected] / [email protected]

  • Added EFT for γγ → AZ, according to Sylvain and Gero's computations. Datacard: dataQED_AZanom
  • In 2017-02-15 corrected the ME to include two operators which induce the Zγ process.

2016-09-23 Cristian Baldenegro [email protected] / [email protected]

  • Correction for γγ → Spin2 → γγ (-1 factor when calling Mxxxx matrix elements)
  • Couldn't run dataQED_ZZanom anymore; now it's corrected.

2016-06-20 Cristian Baldenegro [email protected] / [email protected]

  • Exclusive γγ → HH (IPROC=16071) and γγ → Dijet (IPROC=16070) were included
  • Matrix elements calculated by Gero von Gersdorff and Sylvain Fichet
  • Correspond to Datacards: dataQED_HHexoticSPin0EvenResonances and dataQED_GluGluexoticSpin0EvenResonances respectively
  • New parameters (F0H and F0G)

2016-05-20 Cristian Baldenegro [email protected] / [email protected]

  • Exclusive γγ → ZZ (IPROC=16066) and γγ → γZ (IPROC=16068)
  • Exclusive γγ → W^+^W^-^ (IPROC=16067) and γγ → γγ (IPROC=16069) processes included
  • Helicity amplitudes from Gero von Gersdorff and Sylvain Fichet
  • Corresponding datacards:
    • dataQED_ZZexoticSpin0EvenResonances and dataQED_AZexoticSpin0EvenResonances
    • dataQED_WWexoticSpin0EvenResonances and dataQED_AAexoticSpin2Resonances
  • New parameters F0Z (1/coupling for ϕ → ZZ), and AF0ZG (1/coupling for ϕ → γZ)
  • New parameter F0W (1/coupling for ϕ → W^+^W^-^)
  • Such exclusive productions are included in the same subroutine calling section as Matthias' (AAANOM=3, AAEXOTIC=1)

2015-07-24 Matthias Saimpert [email protected]

  • Important bug corrections: symmetry factor was omitted for γγ → γγ, now added. As a result, γγ → γγ xsec twice smaller

2015-06-25 Matthias Saimpert [email protected]

  • exclusive γγ → γγ studies, exotic spin 0-even resonance added
  • IPROC=16065, associated datacard, dataQED_AAexoticSpin0EvenResonances
  • new parameters AAF0 (1/coupling), AAW (width const), AAA2 (dumping factor for √s dependence of the width)

2015-01-20 Christophe Royon [email protected], Murilo Rangel [email protected]

  • correct for normalisation for reggeon (applied in PDFs and not in flux)

2014-11-26 Christophe Royon [email protected]

  • new code for heavy ion flux (NFLUX=11)
  • new cards to transmit BMIN
  • new code and fluxes for proton ion, ion proton via Pom/Photon exchange
  • bug fix for photon pom

2014-09-11 Matthias Saimpert [email protected]

  • Fix for γγ → γγ, high energy limit implemented (√s ≫ m)
  • Final release for γγ → γγ :)

2014-08-18 Matthias Saimpert [email protected]

  • Anomalous γγ → γγ with compHEP routine found to be wrong (around a factor 2.1 too small)
  • Code from Gero and Sylvain replaced the compHEP routine, everything is now in agreement
  • Possibility to switch back to compHEP routine by commenting/uncommenting fpmc.f l. 3435
  • The new EFT routine takes interferences with SM γγ production via W loop into account

2014-03-20 Matthias Saimpert [email protected]

  • General update/upgrade of the QED Diphoton exclusive process
  • IPROC=16060, SM QED Exc diphoton production (W + massive fermions loops included)
  • (old routine is IPROC=19800 kept for comparison purpose but is most likely to be WRONG)
  • IPROC=16061, SM QED Exc diphoton production at high mass (massive fermion loops EXCLUDED)
  • IPROC=16062, SM QED Exc diphoton production at low mass (W loop EXCLUDED)
  • IPROC=16063, General exotic vector contributions with SM interf (SM fermion loops EXCLUDED)
  • IPROC=16064, General exotic fermion contributions with SM interf (SM fermion EXCLUDED)
  • Corresponding datacards added

2014-01-21 Christophe Royon [email protected]

  • with Goergiy Stelmakh,
  • add Reggeon (NFLUX=10), Pomeron-Reggeon (NFLUX=19), Reggeon Pomeron (NFLUX=21)
  • Photon-Pomeron (NFLUX=20), Pomeron-Photon (NFLUX=22)

2013-12-12 Matthias Saimpert [email protected]

  • Adding γγ → γγ anomalous couplings (IPROC=16016) based on arXiv:1311.6815 [hep-ph]
  • Adding ~/External/comphep_interface/sqme_aaaa folder
  • Modifications of ~/Examples/ffcard., module., module_reco., fpmc_main. and Fpmc/fpmc.

2013-03-26 Oldrich Kepka [email protected]

  • Adding setup_lxplus.sh, to be used on lxplus to configure CERNLIB

2012-06-05 Rafal Staszewski

  • New Examples/fpmc_main.f created to supersede module.f and module_reco.f. module and module_reco are disabled in the Makefile. The new executable is called fpmc.

  • The information from jet alg. was not stored into ntuple. A change in External/ntuple.f was needed to fix it.

  • New OUTPUT option added to steering, determining the generator output. Possible values:

    • 0 : Only the text output with the cross section at the end.
    • 1 : Ntuple with few histograms and a list of particles for each event.
    • 2 : Jet CONE algorithm is performed and its output is also stored in the ntuple.

2011-05-09 Oldrich Kepka [email protected]

  • Tagging version fpmc_v01-05
  • cleanup of ntuples, version for testing
