Dear ShinIchi

 

Thank you for your nice suggestion and patient explanation, which was very useful to me.

Best Regards

Dear Youquan

Thanks for the presentation in the PWG meeting today.

As Nu mentioned, one would like to exclude the pair from the Q-vector to

define the event-plane in order to prevent the effect from the auto-correlation

between the pair and the event plane, for this purpose, you might like to exclude

the pair of the tracks from the Q-vector of your full event-plane from the TPC,

when you calculate the pair angle with respect to the event plane for each

pair-by-pair.

If you use the event plane from EPD, you do not need to worry about this

auto-correlation, although the resolution of TPC Psi2 would be much better…

If you use TPC sub-event plane (Ease and West), we could avoid the auto-

correlation with some loss of pair at the mid-rapidity (if you require both

tracks to be in one side of TPC), but we might still gain the resolution than

EPD even with half TPC especially for the Psi2/3 resolution. For this case,

event mixing could be somewhat complicated, since you might like to have

those 2 planes to be similar in the mixed event. So you might need 4D event

category class (Cent, Zvtx, PsiE, PsiW). EPD Psi1 plane could also be useful

as well, especially if you are interested to go into the source tilt measurement

in addition to the eps2 and eps3 measurements. I hope it’s clear for you...

Best regards, ShinIchi

Dear Hanna and Nu,

I would like to give a presentation about pion femtoscopy in O+O collisions at 200 GeV.

I will upload my slides as soon as possible.

Best regards,

Youquan Qi
