sPHENIX is a new detector at RHIC.

["Li, Xuan" <xuanli AT lanl.gov>]

Dear Gunther,
           I would like to submit the following abstract to the coming 
DNP2017 conference about the MVTX project and the R&D efforts. Please see the 
abstract below.

Study of bottom production with the future silicon pixel vertex detectors at 
RHIC
Xuan Li for the sPHENIX Collaboration
The proposed next generation heavy ion experiment at RHIC, the sPHENIX 
experiment, aims to study the microscopic nature of the Quark Gluon Plasma 
(QGP) with hard probes such as jets and heavy flavor production. The bottom 
quark is expected to be produced in a hard scattering before the QGP creation 
in heavy ion collisions due to its high mass ($m_{b} > \Labmda_{QCD}$) and 
can traverse the medium. Production of bottom quark tagged jets (b-jets), B 
hadrons and their correlations at sPHENIX probe different partonic 
subprocesses. sPHENIX measurements are complementary to the ones at the LHC, 
covering different QGP properties, such as QGP density, temperature and 
viscosity. Such measurements are essential for our understanding of the 
bottom quark energy loss mechanisms in the QGP medium. To achieve these 
goals, the sPHENIX experiment will utilize a state of the art silicon vertex 
detector based on the Monolithic-Active-Pixel-Sensor (MAPS) technology. Such 
a MAPS-based vertex detector (MVTX) can provide a factor of 10 better spatial 
resolution in the displaced vertex measurement of open heavy quarks over the 
current PHENIX capability. The MVTX performance and the physics projections 
of b-jet and B hadron measurements will be presented, using the projected 
luminosities in continuous sPHENIX operations from 2022-2027 in 200 GeV 
$p$+$p$ and Au+Au collisions.  The status of the MVTX R&D will also be 
reported.

          Suggestions or comments are very welcome!
          Thanks.
                                                                              
                                 Xuan

Subject: [Sphenix-l] Abstracts/speakers for DNP meeting?

Friends,

If anyone is going to the DNP meeting this fall, and would like to give an 
sPHENIX related talk, please let us know asap (abstract deadline is 6/30). 
John has provided a draft for a broad sPHENIX abstract, but there is plenty 
of room for more contributions. In particular a talk related to tracker 
design and HF related capabilities would be valuable.

Best,

Gunther and Dave
