The charmonium photo/electro-production close to threshold can be used, under certain assumptions, to study the the gluon properties of the nucleon such as gluon form factors, mass radius of the proton, and the anomalous contribution to the proton mass. I will present analysis of the existing JLab J/psi data discussing the possibility of extracting gluon form factors based on some general...
This talk will discuss upcoming tagged deep inelastic scattering (TDIS) measurements at Jefferson Lab, which will directly probe the elusive mesonic content of the nucleon. The TDIS experiment will measure low momentum recoiling (and spectator) hadrons in coincidence with deep inelastically scattered electrons from hydrogen (and deuterium) targets. Through use of a recoil detector, a tagging...
On behalf of the CLAS Collaboration
Studies of nucleon resonance electroexcitation amplitudes are providing insight into many facets of strong QCD dynamics. These amplitudes have become available from the analyses of exclusive electroproduction experiments at Jefferson Lab with CLAS in the range of momentum transfers up to 5 GeV$^2$ and are currently extended to momentum transfers up to 10...
Understanding the strong interaction dynamics, which triggers the emergence of hadron mass (EHM), presents a challenging problem within the Standard Model of particle physics. Experimental extraction of electromagnetic and transition form factors of mesons and baryons for increasingly larger virtual photon four-momentum squared (i.e., photon virtuality,) as well as their more complete...
This presentation covers recent advancements in the refined simulations of double pion electroproduction for CLAS22. Double pion production provides a valuable probe of baryon structure, requiring accurate simulations for proper interpretation of experimental data. The presentation addresses the feasibility of extending the kinematic coverage beyond CLAS12, discussing resolution and acceptance...
Using Thomas Jefferson's National Accelerator Facility's 10.6 GeV beam
and the CLAS12 large solid angle spectrometer, inclusive electron proton cross sections were measured over a wide kinematic range from the pion threshold up to an invariant mass W of 2.55 GeV, for ten Q^2 bins between 2.5 and 10.4 GeV^2. These results were validated against existing world data set in the overlap region and...
At J-PARC, a project to extend the Hadron Experimental Hall is underway, where various nuclear and hadron physics experiments will be conducted. Among them, the precision spectroscopy of $\Lambda$ hypernuclei stands as one of the flagship experiments. Recently, at JLab, new $\Lambda$ hypernuclear experiments using electron beams have been approved, and hypernuclear spectroscopy will be...
One of the main challenges in the extraction of Generalized Parton Distributions (GPDs) from the currently available experimental data is that experimental observables can access only two of three variables, x, ξ, and t, that define the GPDs. The variable 𝑥 is integrated over in the DVCS and TCS amplitudes due to the loop in the “handbag” diagrams. The only information that can be accessed in...
