Thanks Jakub for the quick update.

Unfortunately, I won't be able to connect today for your presentation. 

Will check the discussion from the recording and let you know in case of further questions. 

Cheers,

Barbara

Dear Barbara,

thank you for your comments. Please find and updated version of the presentation (same link, https://drupal.star.bnl.gov/STAR/blog/ceskajak/HP-PWG-meeting-150823).

The pT bin fits (slides 24-29) are the first approach and can definitely be improved. The 0-2 GeV/c bin would need a different background shape, as the exponential does not work here). The plots show a comparison of fits with Leszek's constraints (left) and with larger, arbitrarily chosen constraints (right). Again, relaxing the constraints improves the accuracy of the signal fit.

The constrained values used previously and the current values can be found again on slides 22 and 23. The fit does not seem to succeed for any unbound signal width and tends to grow to unexpectedly large values of sigma. The upper constraint of 0.3 was chosen arbitrarily.

Best regards,
Jakub

Hi Jakub,

thanks for the update. It looks like the peaks are wider. If it's quick, can you do the same exercise for Upsilon signal divided in Upsilon pT bins ? 

It would be useful to add comparison of  numerical values between the previous constraint from Leszek fit parameters (mean and width) and the ones that your new fit prefers. 

And it would be good to see in more detail what happens with the signal's width for J/psi in Brennan's analysis. 

Cheers,

Barbara

Dear Barbara,

thank you for your comments. I have tried relaxing the widths (and the means) of the CB functions. This appears to cover the signal better. Please see slides 22 and 23 in the attached presentation: https://drupal.star.bnl.gov/STAR/blog/ceskajak/HP-PWG-meeting-150823

As for the embedding, I am working on it, but have no results yet.

Best regards,
Jakub

Hi Jakub,

thanks for the update on the fitting.

Looking at your slide 20, it seems that this left tail is part of the signal. Could you please check what happens if you make looser constraints to your Upsilon signal width.

Also, have you had a chance to look at the embedding to see if you get such a wide signal there ? 

Cheers,

Barbara

Dear all,

I will report on the questions raised last week and present an update on the status of the analysis of the Run17 Upsilons.

If possible, I would like to present at the beginning of the meeting, as I will need to leave by 12 EDT.

Best,

Jakub

Hello Nihar and all,

I will give an update on track merging issue for D0-hadron femtoscopy. I will upload my slides later.
