Measurement of the Ar(e,e $^{'}$ p) and Ti(e,e $^{'}$ p) cross sections in Jefferson Lab Hall A

L. Gu, D. Abrams, A. M. Ankowski +58

The E12-14-012 experiment, performed in Jefferson Lab Hall A, has collected exclusive electron-scattering data (e,e $^{'}$ p) in parallel kinematics using natural argon and natura…

Ruling out color transparency in quasi-elastic $^{12}$ C(e,e'p) up to $Q^{2}$ of 14.2 (GeV/c) $^{2}$

D. Bhetuwal, J. Matter, H. Szumila-Vance +87

Quasielastic $^{12}$ C $(e, e^{'} p)$ scattering was measured at space-like 4-momentum transfer squared $Q^{2}$ ~=~8, 9.4, 11.4, and 14.2 (GeV/c) $^{2}$ , the highest ever achieved to date. Nucl…

Photoproduction of the $f_{2} (1270)$ meson using the CLAS detector

M. ~Carver, A. ~Celentano, K. ~Hicks +137

The quark structure of the $f_{2} (1270)$ meson has, for many years, been assumed to be a pure quark-antiquark ( $q q ˉ$ ) resonance with quantum numbers $J^{P C} = 2^{++}$ . Recently,…

Advanced extraction of the deuteron charge radius from electron-deuteron scattering data

Jingyi Zhou, Vladimir Khachatryan, Haiyan Gao +11

To extract the charge radius of the proton, $r_{p}$ , from the electron scattering data, the PRad collaboration at Jefferson Lab has developed a rigorous framework for finding the b…

Probing the Deuteron at Very Large Internal Momenta

Carlos Yero

$^{2} H (e, e^{'} p) n$ cross sections have been measured at 4-momentum transfers of $Q^{2} = 4.5 \pm 0.5$ (GeV/c) $^{2}$ over a range of neutron recoil momenta, $p_{r}$ ,…

Extraction of beam-spin asymmetries from the hard exclusive $π^{+}$ channel off protons in a wide range of kinematics

S. Diehl, K. Joo, A. Kim +135

We have measured beam-spin asymmetries to extract the $sin ϕ$ moment $A_{LU}^{s i n ϕ}$ from the hard exclusive $e p \to e^{'} n π^{+}$ reaction above the resonance region, fo…
