Antibaryon Photoproduction Using Clas At Jefferson Lab, William B. Phelps

FIU Electronic Theses and Dissertations

Antibaryon production has been investigated since the advent of nuclear

physics, largely motivated by the potential for baryon-antibaryon bound states.

Due to the recent availability of high statistics experiments there has been a

renewed interest in how antibaryons are created in photoproduction. The g12

(E04-005) experiment conducted at Thomas Jefferson National Accelerator Fa-

cility used the CEBAF Large Acceptance Spectrometer to provide the world’s

largest dataset for baryon-antibaryon photoproduction on a liquid hydrogen tar-

get. The focus of this work is to investigate the photoproduction mechanism of

γp → ppp ̄ through detailed differential cross section measurements from 3.95

to …
