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,…

Measurement of the Generalized Polarizabilities of the Proton at Intermediate $Q^{2}$

H. Fonvieille, J. Beričič, L. Correa +35

Background: Generalized polarizabilities (GPs) are important observables to describe the nucleon structure, and measurements of these observables are still scarce. Purpose: This pa…

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…

Modified Structure of Protons and Neutrons in Correlated Pairs

B. Schmookler, M. Duer, A. Schmidt +6

The atomic nucleus is made of protons and neutrons (nucleons), that are themselves composed of quarks and gluons. Understanding how the quark-gluon structure of a nucleon bound in…

Probing the core of the strong nuclear interaction

A. Schmidt, J. R. Pybus, R. Weiss +162

The strong nuclear interaction between nucleons (protons and neutrons) is the effective force that holds the atomic nucleus together. This force stems from fundamental interactions…
