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

Multinucleon Short-Range Correlation Model For Nuclear Spectral Functions, Oswaldo Artiles

FIU Electronic Theses and Dissertations

The main goal of the research presented in my dissertation was to develop a theoretical model for relativistic nuclear spectral functions at high missing momenta and removal energies based on the multi-nucleon short-range correlation (SRC) model. The nuclear spectral functions are necessary for the description of high energy nuclear processes currently being studied at different labs such as JLAB, LHC and FNAL.

The model followed the effective Feynman diagrammatic approach in order to ac-count for the relativistic effects important in the SRC domain. In addition to the two-nucleon (2N) SRC with center of mass motion contribution, the contribution of the …
