Detecting The Phi Meson With Clas12, Paul Simmerling
Honors Scholar Theses
Analysis and detection of the phi(1020) vector meson from exclusive electroproduction decay into Kaons have been performed. Studying exclusive phi electroproduction is an ideal channel for quantifying the gluonic properties of the nucleon. This detection used the CEBAF Large Acceptance Spectrometer (CLAS12) at Thomas Jefferson National Accelerator Facility (JLab) with a 10.6 GeV longitudinally polarized electron beam and an unpolarized hydrogen target. Using the detected final state particles phase space, x_B, Q^2, W, and by developing specialized exclusivity cuts as well as several additional cuts, events containing the production of a phi(1020) meson were able to be extracted. Additionally, a …

A Consistent Classical Relativistic Model Of A Finite Size Particle, Mira Varma
Honors Scholar Theses
An exactly solvable classical field theoretical model of a stable particle of finite size is studied. The model consists of a "swarm" of matter particles bound by an interplay of three static fields: one electromagnetic field, a massive scalar field, and a massive vector field. The internal forces due to the three fields balance each other to form a stable particle. The model parameters can be chosen such that the described particle has the mass and radius of a proton. The model qualitatively reproduces the pressure distribution inside a proton in agreement with recent experimental findings.
