STAR task force for tuning PYTHIA

[Raghav Kunnawalkam Elayavalli <kunnawalkamraghav AT gmail.com>]

Hi Yuanjing,

Thanks for your slides and sorry i wasnt able to attend the meeting yesterday. I have a couple of questions in your analysis - looking at your plots, while i would not expect pythia to exactly reproduce the data, it looks like there is a systematic shift in the comparison...

1) why do you have a BBC trigger in your code? We use that as a minbias trigger yes? and when you generate pythia, it is by definition having some activity in the event.  do you have cases where your BBC trigger fails? 

2) when you fill the pT histograms, why do you fill with the inverse pT weight?   

Cheers

Raghav
