sPHENIX cold QCD topical group

["Aidala, Christine" <caidala AT bnl.gov>]

Minutes from today’s meeting:

 

Nils Feege + Christine Aidala – Topical Group News

--------------------------------------------------------------

An abstract on cold QCD physics at sPHENIX has been accepted to DIS in Kobe, with the speaker still to be determined.  If you are interested in giving the talk on behalf of sPHENIX, contact the TG conveners and spokespersons.

 

There was an Outer HCal Steel Procurement Readiness Review at BNL on January 31^st.  Christine gave a presentation on the compatibility of the barrel steel design with future EIC measurements.  Note that the plug doors in the forward and backward acceptance regions were NOT part of the review, only the steel at midrapidity, serving for both the Outer HCal and flux return.

 

 

Greg Kalicy, Marie Boer (CUA) – DIRC Simulations in Fun4All for an EIC Detector

--------------------------------------------------------------------------------------------------

Implementing a DIRC design similar to one developed for JLab EIC detector in the sPHENIX Fun4All software framework.  Shorter (3000 mm length to accommodate BaBar solenoid) than JLab design, which is over 4 m.  Radiator material is synthetic fused silica, same as BaBar DIRC. 

 

p. 3 – Plots are accumulated statistics for many events thrown at the given angles.  Brighter colors are photons that arrive earlier, darker colors later.  Time resolution of ~100 ps expected, mostly determined by the electronics.  Will use two different reconstruction methods, one relying mainly on geometry with timing information used to reduce background, and one relying mainly on timing information.  The latter method is planned for the future TOP detector at Belle-II, which will be the next DIRC to run since the BaBar one.

 

Pawel Nadel-Turonski (JLab) – Extended (Near-Beam) Detection for e/sPHENIX

------------------------------------------------------------------------------------------------

Presented nice overview of physics motivations and requirements for low-Q^2 electron detection, “near” hadron detection, and “far” hadron detection in e+p and e+A.  “Near” hadron requirements are currently being considered—need to make sure that considerations for low-Q^2 electron and “far” hadron measurements get addressed as well.

Dear Cold QCD enthusiasts,

 

our next meeting is scheduled for

 

Monday, February 5, 8:30pm ET.

 

The meeting is BlueJeans only (https://bluejeans.com/345777492) with the agenda evolving at https://indico.bnl.gov/conferenceDisplay.py?confId=4193

 

If you would like to present something (either at this meeting or at the next one on 2/19), please let Christine and me know and we will happily put your name on the agenda.

 

We look forward to hearing you at the meeting.

 

Best,
