Description
We have measured the flavor dependence of charged pion multiplicities in SIDIS from proton and deuterium targets to explore charge symmetry violation in pion fragmentation functions. The data were collected using 10.2 and 10.6 GeV electron beams in Hall C at Jefferson Lab. The same data set also contains high-momentum protons from SIDIS events, which we are now analyzing to extract proton multiplicities and cross sections. Focusing on positive polarity runs and using Hall C’s high-precision detectors for particle identification, we aim to isolate SIDIS protons and investigate possible signatures of baryon junctions—gluonic field configurations that may carry baryon number independently of valence quarks. We will outline our experimental approach to test predictions related to the baryon junction mechanism.
