ePIC_JPsi

Repository containing some simple analysis scripts as well as instructions for producing the necessary files required for analysis.

lAger Instructions

Install version 3.61

Follow the install instructions in the README of that repo.

10x130

Run with the .json file included in this repository: lager -c jpsi-10on130.disp-jpsi-00-muon.json -r 1 -o <OUTPUT_DIRECTORY>

Process the lAger output through the afterburner using the config ip6_hiacc_100x10

abconv -p ip6_hiacc_100x10 <OUTPUT_DIRECTORY>/lager-vmp-00mrad.jpsi-10on130.4pi.disp-jpsi-00-muon.run00001-lumi10.hepmc -o <OUTPUT_DIRECTORY>/ab_output-00mrad.jpsi-10on130.4pi.disp-jpsi-00-muon.run00001-lumi10

10x250

Run with the .json file included in this repository: lager -c jpsi-10on250.disp-jpsi-00-muon.json -r 1 -o <OUTPUT_DIRECTORY>

Process the lAger output through the afterburner using the config ip6_hiacc_275x10

abconv -p ip6_hiacc_275x10 <OUTPUT_DIRECTORY>/lager-vmp-00mrad.jpsi-10on250.4pi.disp-jpsi-00-muon.run00001-lumi10.hepmc -o <OUTPUT_DIRECTORY>/ab_output-00mrad.jpsi-10on250.4pi.disp-jpsi-00-muon.run00001-lumi10

18x275

Run with the .json file included in this repository: lager -c jpsi-18on275.disp-jpsi-00-muon.json -r 1 -o <OUTPUT_DIRECTORY>

Process the lAger output through the afterburner using the config ip6_hiacc_275x18

abconv -p ip6_hiacc_275x18 <OUTPUT_DIRECTORY>/lager-vmp-00mrad.jpsi-18on275.4pi.disp-jpsi-00-muon.run00001-lumi10.hepmc -o <OUTPUT_DIRECTORY>/ab_output-00mrad.jpsi-18on275.4pi.disp-jpsi-00-muon.run00001-lumi10

hepmc3ascii2root

For all configurations, the output file was converted to a .hepmc3.tree.root file, and renamed to comply with simulation campaign naming.

./hepmc3ascii2root <OUTPUT_DIRECTORY>/ab_output-00mrad.jpsi-<ELECTRON ENERGY>on<PROTON ENERGY>.4pi.disp-jpsi-00-muon.run00001-lumi10.hepmc <OUTPUT_DIRECTORY>/lAger_v3.6.1_DVMP_JPsi_<ELECTRON ENERGY>x<PROTON ENERGY>ep_q2_1to50.hepmc3.tree.root

Output Files

The resulting output files for both configurations, to be used for the simulation campaigns are located at:
