In summer 2007, we started to work on fsim6(*), a fast simulator for Belle/Super-Belle; today I will tell you:
(*) fsim6 is a rewrite of the old Belle fast simulator fsim5 in C++
Performance same as Belle under 20 times higher background condition (LoI version)
+ iron yoke
(0.3X0-0.2X0 = 0.1X0)
Si striplet (MAPS later) for inner 2 layers; Si strip for outer 4 layers
SuperKEKB Letter of Intent (LoI) (KEK Report 04-4)
tune fsim6 parametersto model Super-Belleperformance
Geant 3(present Belle MC),Geant 4 and others
Large data sets and different detector setups can be studied quickly in terms of actual physics performance in the benchmark modes
existing Belle analyses
See talks by T.Kawasaki-san and T.Hara-san
E = 100 MeV
E = 300 MeV
E = 500 MeV
E = 1 GeV
tuning only up to 1 GeV
tuning up to 3.5 GeV
The variables #1 to #3 require track-cluster matching which is not implemented in present fsim6
(2 is the discriminant used by the eid software)
matching efficiency barrel
Linear with log(p)?
