Minutes:

Sushanta:

  • Pythia had a problem, that all nucleons were produced at xyzt=(0,0,0,0)
  • now the correct setting is used and the space-time information can be accessed
  • Started implementing the thermal FIST resonance cocktail in pythia for resonances up to 2GeV mass =93% of all protons (same list as is used in EPOS)

Luca:

  • EPOS productions are processing well
  • cm2_tiny and mpp3 were heavily used by other users, but nontheless we managed to now have a total of 204M events from these productions in addition to the ~100M events we already have locally giving us a total of 300M Events
  • The production will continue

Bhawani:

  • Expressing the Hulthén wave function of the  deuteron using Legendre polynomials looks very promising as it allows to handle the linear exponents
  • Will start with the calculation soon

Maxi:

  • implemented the new forced core source model
  • the core source size and mT scaling is (by construction) very well reproduced by the model
  • The effective source size however is drastically increased compared to the measurement
  • The problem could be due to an error in the Lorentz boost
  • This will be further investigated once TPC-QC is finished
There are minutes attached to this event. Show them.
