Extremely high-energy bremsstrahlung in matter
Peter Arnold, Joshua Bautista, Omar Elgedawy +1
The theory of bremsstrahlung by extremely high energy electrons passing through ordinary matter has been qualitatively incomplete. We revisit the suppression of bremsst…
Calculating extremely high energy bremsstrahlung in matter
Peter Arnold, Joshua Bautista, Omar Elgedawy +1
Ultra-relativistic electrons initiate electromagnetic showers in ordinary matter that evolve through bremsstrahlung and pair production. At very high energy, the quantum mechanical…
Revisiting extremely high energy QED bremsstrahlung in matter: large modifications to the LPM effect
Peter Arnold, Joshua Bautista, Omar Elgedawy +1
Very high energy electrons initiate electromagnetic showers in ordinary matter that branch and multiply through bremsstrahlung and pair production. At extremely high energies, the…
Likelihood and Correlation Analysis of Compton Form Factors for Deeply Virtual Exclusive Scattering on the Nucleon
Douglas Q. Adams, Joshua Bautista, Marija Cuic +11
A likelihood analysis of the observables in deeply virtual exclusive photoproduction off a proton target, $ep \rightarrow e' p' γ'$, is presented. Two processes contribute to the…
Variational autoencoder inverse mapper for extraction of Compton form factors: Benchmarks and conditional learning
Fayaz Hossen, Douglas Adams, Joshua Bautista +8
Deeply virtual exclusive scattering processes (DVES) serve as precise probes of nucleon quark and gluon distributions in coordinate space. These distributions are derived from gene…
The Correlated Spatial Structure of the Proton: Two-body densities as a framework for dynamical imaging
Zaki Panjsheeri, Joshua Bautista, Simonetta Liuti
We present results on two-parton densities in coordinate space, which capture a fuller dynamical picture of the proton's internal structure, including information on the relative p…
