1. March 31, 2020, Tuesday, 10:00am Beijing time.

1) Pile-up issues in the fluctuations analysis - Sam and Arghya

(For the good run list for 3.0 GeV, I suggested a set of runs which should

have less pile-up issues... can we check to see if that indeed improves

issues?)

2) dE/dx gain sag for near target rapidity - Hui raised this issue today at

the LFSUPC meeting. Ben has some pi, K, p results which might be relevant.

Ning Yu suggested that this issue started to show up with the runs in 2014,

which would support Yuri's calibration argument.

3) GEANT corrections for knock-out particles (protons, deuteron, tritons,

He3, Alphas) -- Can discussion what GEANT can produce (i.e. does it make

light nuclei?) How much effect do we expect from the pipe and from the

target?

4) Efficiency corrections -- We have efficiency corrections from the 4.5

GeV Test run in 2015. The detector has not changed too much (although the

target was moved by 10 cm). Can we use these to get preliminary efficiency

corrections for the 3.0 GeV analysis? (Sam, Matt, Usman)
