These studeis look at Deep Exclusive Meson Production (DEMP) reactions where we have a pion, electron and neutron in the final state. The neutron is very forward focused and will be detected in the ZDC. The pion and electron are detected in central detectors.
These events use a custom event generator which can be found here - https://github.com/JeffersonLab/DEMPGen
I've produced files from this generator and processed them through the ATHENA simulation. The next step is to analyse the events and see how well the events of interest can be identified. Goals of the benchmark are as follows -
1. Identify pi/e'/n tripe coincidence events
2. Produce event distributions for events of interest
3. Determine event rates binned in Q2 and -t, from this form factor values can be projected
To begin with, I'll just extract and plot some basic event information (at truth level to begin with) for the processed DEMP events. The end goal is effectively to add a new set of points to the attached plot where we have projections from the ATHENA simulation too.![fpi_ecce_err21](/uploads/d8a0852dccdb2b7d8645ae5f5fc4f097/fpi_ecce_err21.png)
If this works well, the next step would be to try and create a similar benchmark for Kaon FF studies.Stephen JD KayStephen JD Kayhttps://eicweb.phy.anl.gov/EIC/benchmarks/physics_benchmarks/-/issues/2DVMP process benchmark2024-01-08T16:45:14ZWhitney ArmstrongDVMP process benchmarkAdd a deeply virtual meson production benchmark.Add a deeply virtual meson production benchmark.First Physics Benchmark
