Agenda [attended: Moskov, Mikhail, Mark, Justin, Volker, Chan, and Igor]

1) Event generators:

Nick: I have updated the generator with the reactions we talked about at the previous meeting. I will have more time to work on things next week when I will be back at Edinburgh. I will keep you posted with updates.

Franz: I modified the geant3 and geant4 geometry to include the Beryllium target (+shielding). A simple geant3 view is attached [[]]. Also I generated and ran 100k K0 p -> pi+ Lambda events but yesterday evening could not figure out why the tracking wasn't efficient (on hdview2 (event display) it looks like many hit patterns should have been reconstructed ... but I think this will be solved shortly).

2) MC News (Mikhail) [[]]

Justin: From the meeting today it seems that you would like a new calibration context in CCDB for the klong simulations which seems quite reasonable. I would suggest we collect a list of settings you need specified for your simulation and then we can request these under a new context called "mc_klong". So the two tables I'm aware of that you need modified are

rf_period = 64 beam_period = 64

Simon, what magnetic field did you use in your studies https://www.jlab.org/conferences/kl2016/talks/tuesday/taylor.pdf? It might be useful to try something near our nominal field like 1200 A (solenoid_1200A_poisson_20160222) and a lower field setting of maybe 800 A (solenoid_0800A_poisson_20160222).

There is a mapping in the solenoid_map table which specifies a magnetic field setting for a given run number. So we should choose 2 different run numbers and assign these 2 field settings for them so you can generate events which will have different fields.

Simon: I did the simulations at 1300 A.

3) n-calculations (Igor) [[]]

4) Meson spectroscopy

Volker: Next time

5) CP violation

Moskov: Next time
