Simulations of beam particle interaction in the target have been used to estimate the background affecting the experiment, optimize the detector configuration, and determine the maximum acceptable luminosity. Lessons learned from CLAS12 background simulation studies will be discussed.
Deeply Virtual Compton Scattering (DVCS) is a privileged channel to study the structure of the nucleon as their experimental observables let us access information about Generalized Parton Distributions (GPDs). In general, the identification of DVCS events relies on the detection of only two final state particles as the kinematics of the third one can be reconstructed from conservation laws....
We investigate the corrections to the beam asymmetries in parity-violating electron scatterings arising from charge symmetry violation, strange quark, and charm quark distributions. Based on the parton distributions from the NNPDF Collaboration, these corrections could lead to $(1$-$2)\%$ uncertainties in the extraction of the weak couplings $g^{eq}_{AV}$ and $g^{eq}_{VA}$, and as large as...
The extraction of form factors, radii and related quantities have been
an important focus of research in the last decades. The research
intensity has increased with the proton radius puzzle about a decade ago, and more recently with results on the gravitational form factors. But the field is much wider, including also weak form factors, other radii and a multitude of particles beyond the...
