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…

Are Parton Showers in a Quark-Gluon Plasma Strongly Coupled? A Theorist's Test
Peter Arnold, Omar Elgedawy, Shahin Iqbal
We study whether in-medium showers of high-energy quarks and gluons can be treated as a sequence of individual splitting processes or whether there is significant quantum overlap b…
