Generalized Parton Distributions (GPDs) are a huge advancement in our understanding of hadronic structure and non-perturbative QCD. To study GPDs, one may use the Deep Exclusive Meson Production (DEMP) reaction. The PionLT experiment in Jefferson Lab Hall C measures the DEMP reaction, but to access GPD information we must perform a LT separation on the data. An LT separation divides the...
Due to the dramatic running of the QCD coupling constant $\alpha_S$, hadronic structure varies drastically with measurement scale. Therefore, combining complementary measurements of many unique observables is key to completing our picture of the proton. The KaonLT experiment at Jefferson Laboratory probes hadron structure through measurements of Deep Exclusive Meson Production (DEMP)...
Hadronic physics aims to understand the contribution and dynamics of quarks and gluons in the formation of hadrons. Quantum Chromodynamics predicts a number of states, including those having gluonic degrees of freedom called hybrids, but only a few have been established experimentally. The GlueX experiment at Jefferson Lab, USA, utilizes a linearly polarized photon beam of 8-9 GeV and a large...
Relativistic heavy-ion collisions are reaching temperatures where the quarks and gluons, fundamental constituents of the nucleus, become deconfined and enter a state called the Quark-Gluon plasma (QGP). Its properties are a window into the underlying nature of the strong force under extreme conditions of temperature and pressure, which can be inferred from experimental measurement. Like...
One of the central challenges in modern physics is to unravel hadronic structure, as the strongly coupled, non-perturbative nature of QCD at low energies makes it difficult to derive the observed properties of hadrons from their underlying quarks and gluons. The pion ($\pi$-meson) is the lightest quark system, and its properties are deeply linked to our understanding of how quarks are confined...
The principal goal of the GlueX experiment at the Thomas Jefferson National Accelerator Facility is to search for
non-q ¯q mesons, a construction not allowed by the simple quark model but predicted by Quantum Chromodynamics.
Specifically, hybrid mesons, which result from the addition of a gluonic field with exotic states and are pictured as a q¯qg
state, will be accessed using a 8.2-8.8 GeV...
