0004 [Sphenix-software-l] EMCal fast hadron simulation model

0006 I put the first shot on the fast hadron deposit simulator on github in my directory vorosful/emcal

0015 The plot c1.png shows how it works for 4, 8, 12 GeV hadrons with the current values of parameters. The total energy deposit (and relative probabilities) are reasonably close to the full simulations shown in

0021 I tried to provide plenty of inline comments and explanations; it should be sufficient if you want to play with the parameters yourself.
0022
0023 While the code can use plenty more tuning, its advantage is that the components are physics-motivated. It generates the minimum ionizing, hadronic and electromagnetic part of a "generic" hadron in 3 dimensions, and deposits them into the "towers" of an (arbitrary) rectangular detector. This can (and will) then serve as a starting point for a clustering algorithm.
0024
0025 For the moment I stopped tuning the parameters; once better calibrated data from identified hadrons are available - both total energy deposit AND individual showers to tune the shape! - I'll continue.
