sPHENIX MAPS tracker discussion

Hi Ming,

Below is an edited version of the first few paragraphs. As time appears to be of the essence, we're sending comments as we go through the text.

Best,

Gunther and Dave

The sPHENIX detector, currently under development, is designed to study the microscopic nature of the quark-gluon plasma (QGP) through new measurements that probe the QGP over a range of scales. This addresses one of the top scientific priorities for the Hot QCD field specified in in the 2015 NSAC Long Range Plan, exploiting the unique capabilities provided by the Relativistic Heavy Ion Collider (RHIC). Key elements of the sPHENIX Hot QCD program are high statistics studies of fully reconstructed jets, high precision upsilon spectroscopy and a comprehensive program of heavy-flavor measurements. Of particular importance are bottom-quark jets and B-mesons, for which mass effects are expected to play the most significant role.  Precise B-meson measurements offer a unique opportunity to understand the transport properties of QGP at RHIC through the mass dependence of parton energy loss in the QGP medium. Reconstruction and identification of B-mesons requires precision tracking close to the interaction point with high detection efficiency. The proposed upgrade of the sPHENIX experiment with a vertex detector (MVTX) based on Monolithic Active Pixel Sensors, located close to the interaction point, will provide these capabilities, and allow a broad range of measurements over a wide momentum range near mid-rapidity. The MVTX detector will also significantly improve current charm baryon measurements and enable heavy-flavor correlation measurements at RHIC (see Appendix 1).

Dear all,

 

Following the discussions form last MVTX bi-weekly meeting, we have drafted a MVTX executive summary for ALD’s upcoming DOE visit. 

 

Please send your comments/suggestions by NOON tomorrow 10/25 if possible. 

 

Cheers,

Maria, Grazyna, Bob and Ming
