2009.12.20 Ecalgeo-v6.2: embedded LOW_EM cuts after TPC/EEMC overlap fix

Monte-Carlo setup:

  • Throwing one photon per event
  • Full STAR y2006h (latest EEMC-v6.2 and BEMC with LOW_EM cuts, rest of geometry from CVS)
  • Throw part

Combinatorial background subtraction for e+e- signals

Under:

It is common to use the formula 2*sqrt(N++ N--) to model the combinatorial background when studying e+e- signals, e.g.

2009.12.17 Ecalgeo-v6.2: embedded LOW_EM cuts in the calorimeter geometry

Monte-Carlo setup:

  • Throwing one photon per event
  • Full STAR y2006h (latest EEMC-v6.2 and BEMC with LOW_EM cuts, rest of geometry from CVS)
