Hadronization

Hadronization is the process in which free quarks bind together to form a stable, color-neutral hadron.

For our part, we are studying the formation of the omega and f1 mesons. The project is divided into two pieces:

  1. Analyzing the existing eg2 data, that was taken with 5 GeV electron beams.
  2. Preparing for the future experiment after the 12 GeV upgrade.

Part 1 entails mining the eg2 dataset for reaction candidates. The decay channels will contain multiple gamma rays and/or pions. Data mining software has been developed by the Old Dominion University group, led by Dr. Lawrence Weinstein. We will use that software to skim the eg2 data for possible omega and f1 mesons.

Part 2 will involve simulations of the omega and f1 decays in the CLAS12 detector. The simulations will consist of

  • creating events with a custom generator. Possible candidate for the software package is PLUTO++.
  • simulating the detector response with GEMC.
  • analyzing the data with CLAS12 software.
