Mokka vs. LCDG4 Comparison Guilherme, Jeremy Sep.17, 2003
Data Samples Single particle samples, 1000 evts each • 10 GeV muons • 50 Gev pions (flat in phi) • 50 electrons (theta = 60°, phi = 90°) Warning: different kinematics!!
Conclusions • Likely there are still some bugs in LCDG4 • Despite clear disagreements in EM showers between Mokka and LCDG4, they show better agreement among them than with Gismo • None of them are not properly corrected using Gismo-based sampling fractions • More investigations needed
Next steps • Repeat comparisons using projective LCDG4 • Fair comparison: same versions of libraries, same cuts, same kinematics • Find/fix problem with fake peaks in absorber energies
