NPA Seminar: Nicole Lewis, Rice University, "Search for baryon number carrier in photonuclear processes and heavy-ion collisions at STAR"

Baryon number is a strictly conserved quantum number. It is conventionally assumed to be divided equally among the three valence quarks inside each baryon, but this has never been verified experimentally. An alternative model is the baryon junction: a Y-shaped configuration of nonperturbative gluons that is connected to all three valence quarks and carries the baryon number. In this talk we will present two measurements from the STAR experiment which are sensitive the baryon number carrier.
