Physics Simulation Workgroup Meeting

Wednesday 28 Oct 2020, 10:00 → 12:00 Asia/Shanghai

10:00 → 11:00 Report from Huzhou University

s3, why the photon around (eta, phi) = (0.2, 0.2) is not reconstructed. But there is a cluster reconstructed at (eta, phi) ~ （0.6, 5.8). 

s4, Weird band observed on the left plot

s5, photons from pi0 starts to merge at pt~3 GeV/c. It was suggested to look at the opening angle as a function of pi0 pT from the simulation.

s8, left plot, need to check why the distribution is so asymmetric in \Delta \eta direction?

top-right plot, check the distribution in finer pT bins. 

Bottom-right plot, look the difference of two photons' T_measured - T_expected, where T_expected is calculated from the flight length. 

s9, The distributions are before combinatorial background subtraction. The signal at 1.0<pT<1.5 GeV/c should looks fine after background subtraction.

s12, it was suggested to associate the reconstructed pi0 with the input pi0 and look the performance in more detail. 

 

11:00 → 11:30 Status of the Simulation work on MpdRoot

Yan collected many useful information on EMC related simulation. Very nice slides.

She call for more efforts to join the EMC related simulation.

s19, top-left plot, check why the blue and red curve is not different by a factor of 20% at pt~1 GeV/c.
