Dear All,
 As per suggestions from PAC and others, on behalf of the PAs of the 
isobar paper I would like to propose the following abstract.

Title: Search for the Chiral Magnetic Effect with Isobar Collisions at 
√sNN= 200 GeV by the STAR Collaboration at RHIC

Author: PAs of the isobar paper
Type: Oral

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 electro-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 performed a 
blind analysis of a large data sample of approximately 3.8 billion 
isobar collisions of Ru+Ru and Zr+Zr at √s=200 GeV. Prior to the blind 
analysis, the CME signatures are 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. A precision 
down to 0.4% is achieved, as anticipated, in the relative magnitudes of 
the pertinent observables between the two isobar systems. Observed 
differences in the multiplicity and flow harmonics at the matching 
centrality indicate that the magnitude of the CME background is 
different between the two species. No CME signature that satisfies the 
predefined criteria has been observed in isobar collisions in this blind 
analysis.
