sPHENIX HCal discussion

["Lajoie, John G [PHYSA]" <lajoie AT iastate.edu>]

Folks,

 

Bill reminded me that the HCAL meeting tomorrow conflicts with the STAR announcement of their results for the CME effect in isobar collisions. Because of this I’m going to push the start of the HCAL meeting back one hour, until noon BNL time. My apologies if this presents a problem for anyone.

 

Regards,

John

Subject: Announcement on Release of Results on the Search for the Chiral Magnetic Effect with Isobar Collisions at 200 GeV by the STAR Collaboration at RHIC

We are pleased to inform you that the STAR collaboration will announce the results of our blind analysis of the Isobar data probing for evidence of the Chiral Magnetic Effect (CME) during a BNL seminar on Tuesday,  August 31 at 11 am US/Eastern Time.

 

The title of the seminar is "Search for the Chiral Magnetic Effect with Isobar Collisions at 200 GeV by the STAR Collaboration at RHIC”

 

Abstract: The chiral magnetic effect (CME) is predicted to occur as a consequence of a local violation of P and CP symmetries of the strong interaction amidst a strong magnetic field generated in relativistic heavy-ion collisions. Experimental manifestation of the CME involves a separation of positively and negatively charged hadrons along the direction of the magnetic field. Previous measurements of the CME-sensitive charge-separation observables remain inconclusive because of large background contributions. In order to better control the influence of signal and backgrounds, the STAR collaboration has performed a blind analysis of a large data sample of approximately 3.8 billion isobar {^96 _44 Ru + ^96 _44 Ru   and ^96 _40 Zr + ^96 _40 Zr} collisions at the top RHIC energy. Prior to the blind analysis, the CME signatures were predefined as a significant excess of the CME-sensitive observables in Ru+Ru collisions over those in Zr+Zr collisions, owing to a larger magnetic field in the former. The findings from the isobar blind analysis will be reported in this seminar.

 

We plan to submit these results for publication at the same time.

 Please help us spread the word to your colleagues, we invite everyone to attend this seminar.
