sPHENIX MAPS tracker discussion

Hi Yasser,

Very nice slides. I have a few suggestions for you to consider.

1) eta acceptance of MVTX, in the abstract, the number quoted is |eta|<2, while in the first section (Detector Design), it is quoted |eta|<1.1. May want to make it consistent.

2) One important detector parameter MVTX is the detector material thickness. It is a crucial factor to ensure necessary pointing resolution for low momentum. I would suggest to add this in the abstract and in the detector design.

3) "Calibration and Commissioning", could you indicate in the plot what our chosen operating point is? What is the corresponding efficiency and fake rate?

4) "HF project at sPHENIX", in the non-prompt D0 section, I would suggest to add one key physics goal is for "Precision determination of heavy quark spatial diffusion coefficient and its temperature/momentum dependence"

Thank you and With best regards

/xin

Dear colleague

I have upload my poster for QM2023 in sphenix community invenio https://sphenix-invenio.sdcc.bnl.gov/communities/sphenixcommunity/requests/742858ee-ae18-4336-bfd9-20268f8ac092

Any comment and suggestion will be appreciated

thank you
