A collaborative paper, “Signals of strong parity violation in deep inelastic scattering”, has been accepted by Phys. Lett. B for publication. In this work, we consider the possibility that the strong interaction could violate parity symmetry, causing a non-vanishing, new structure function F3. Existing world data on parity-violating deep inelastic scattering (PVDIS) asymmetry from SLAC E122, HERA, and JLab 6 GeV indicate a 1.5 σ deviation from a null result, thus the signal of possible strong parity violation is small but not negligible. Our impact study shows that the planned SoLID experimental program at JLab will have sufficient precision to demonstrate a 5σ effect should the central value of the signal remains the same.

Updated BBCAL ADC gain coefficients (for pass2) are in the DB. Re-calibration of SBS14-70% settings and a couple of SBS8 settings were required. Detailed report can be found here: https://logbooks.jlab.org/entry/4135857

hcalvtp1 is ROC28, hcalvtp2 is ROC29. run 13939 is the first run with VTP readout. Looks like raw window data.

Alex,

The command to run the script is given below. The LUND file directory is in the command and I have added a copy of the gcard and the electron detector geometry file in-case you need them. Of course you will need to change $SCRIPT_DIR to where ever you put the gcard.

Best,

Josh
