Hi, TPC-ers

Daniel Torres has shared the BTOF-measured mass-splitting in the Run 21 OO200 data with the new TPC alignment, as he said at the TPC meeting that he would do.

Looking at his matchflag==1 results for RFF, I see that VPDstart and starless mass-splitting as a function of phi is the same in both cases, and comparing to the mass-splitting seen with the new TPC alignment in Run 19 AuAu 19.6 GeV looks the same as well, so these findings appear rather stable and robust. See slide 7 of my presentation from the ETOF+BES-II workshop from last December here:

Looking at Daniel's FF vs. RFF does show different phi dependencies.

Thanks,

Could you share the mass splitting results with the TPC group? Those can be found here in the summary PDFs, with other plots as the m^2 vs phi plots you mentioned yesterday.

Thank you!
