HERWIG validation report
Today: validation for MC11 (16.6.5.Y, AUET2-LO** tune, HERWIG 6.520)
(SM validation: D. Rebuzzi; SUSY validation: C. Gwenlan)

Fortran HERWIG validation
AIM
• Validation of athena 16.6.5.Y (including MC10JobOptions to MC11JobOptions migration, change to new evgen transform Generate_trf.py, HERWIG version update and
new AUET2-LO** tune) for MC11 production
• Check impact of new “AUET2-LO**” tune for Herwig/Jimmy– details documented in ATL-PHYS-PUB-2011-008
2
validation samples
1. 15.6.14.7, MC10JobOptions, AUET1 tune (Baseline MC10 sample)
2. 16.6.5.3, MC11JobOptions, AUET1 tune [checking athena and HW version updates only]
3. 16.6.5.3, MC11JobOptions, AUET2-LO** tune
Conclusion: no problematic issues observedConclusion: no problematic issues observed
NB HERWIG version updated to 6.520 for MC11 [majority of updates in 6.520 already in our patches for 6.510]

Possibly some observable difference in e.g. jet multiplicity
• Trend appears more to do with athena/HERWIG update than due to PDF/tune change i.e. green and black, run in same athena version but with different tunes, look similar

Summaryvalidation status:
• 16.6.5.3 (MC11JobOptions) checked against baseline of 15.6.14.7 (MC10JobOptions)
– Log files visually checked to ensure correct parameter settings ✔
– Distributions look sensible given new PDF/tune (and HERWIG version)
• AUET2-LO** tune vs AUET1-LO* (using 16.6.5.3; MC11JobOptions)
– Some differences observed in e.g. jet multiplicities
– appears to be to do with (athena/)HERWIG update rather than tune
• (differences are likely understandable; will perform some more checks to pin down in next couple of days)
