Factorization of the triple-collinear splitting function at first order in opacity

Shahin Iqbal, Urs Achim Wiedemann

In strongly ordered collinear limits, triple-collinear splitting functions factorize into products of splitting functions. Here, we investigate whether, and under…

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 bremsstr…

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…

Are in-medium quark-gluon showers strongly coupled? Results in the large- limit

Peter Arnold, Omar Elgedawy, Shahin Iqbal

Inside a medium, showers originating from a very high energy particle develop via medium-induced splitting processes such as bremsstrahlung and pair production. During shower devel…

The LPM effect in sequential bremsstrahlung: incorporation of "instantaneous'' interactions for QCD

Peter Arnold, Tyler Gorda, Shahin Iqbal

The splitting processes of bremsstrahlung and pair production in a medium are coherent over large distances in the very high energy limit, which leads to a suppression known as the…

Thermalization of weakly coupled non-Abelian plasmas at next-to-leading order

Yu Fu, Jacopo Ghiglieri, Shahin Iqbal +1

We employ the QCD kinetic theory, including next-to-leading(NLO) order corrections in coupling constant, to study the evolution of weakly coupled non-Abelian plasmas towards therma…

Tailoring radiation pressure on infinite slab using pair of non-collinear plane waves

R. Ali, R. S. Dutra, S. Iqbal

The electromagnetic field exerts radiation pressure on the matter and tends to move it either in the backward or forward direction due to net optical pulling or pushing force, resp…
