STAR task force for evaluating tracking efficiency uncertainty

[Robert Líčeník <licenik AT ujf.cas.cz>]

Hi Yuri and Peter,

thanks for pointing that out. I am a little surprised to see such a significant effect of the track charge on the efficiency.

Is this the correct way to select only positively charged tracks:

pTi > 0 for K tracks and pTi < 0 for L tracks?

It seems like in the simulation plots we also see some tracks which correspond to negative charge, so I just want to make sure that this is the way to go.

Thanks,
Robert

Hello Robert,

thanks a lot for making the. As Yuri pointed out I only simulated positive poins. Could you try to cut on the charge in both data and simulation?

With best regards,
Petr

Hi everyone,

as discussed during the meeting, I have put together a few slides comparing results from cosmics data and simulation.

Please let me know if you have any suggestions or if you would like to see some additional plots.

The slides are uploaded at the meeting link below:
