High-energy electron-positron beam collisions with large-angle disruptions
W. Zhang, T. Grismayer, L. O. Silva
We show that the beam and field dynamics in high-energy electron-positron () collisions are characterized by a new dimensionless parameter introduced as in th…
Report on the Advanced Linear Collider Study Group (ALEGRO) Workshop 2026
L. Verra, P. Muggli, B. Cross +56
The 7th ALEGRO workshop, hosted by INFN Frascati National Laboratories from 3rd to 5th March 2026, brought together the international Advanced Novel Accelerators (ANA) community to…
An axion framework for Particle-in-Cell codes with Monte-Carlo sampling: emission, absorption, and detailed balance in plasmas
Miles Radford, Ahmed Alsulami, Bertrand Martinez +5
We present an extension of the OSIRIS particle-in-cell (PIC) code that introduces an axion macroparticle species and three axion-production channels commonly used in thermal-plasma…
Plasma wakes driven by Compton scattering: Non-linear regime and particle acceleration
Thomas Grismayer, Fabrizio Del Gaudio, LuÃs O. Silva
We investigate plasma wake generation via Compton scattering from photon bursts, a non-ponderomotive process relevant when the photon wavelength is smaller than the interparticle d…
Anomalous pinch in electron-electron beam collision
W. Zhang, T. Grismayer, L. O. Silva
We show that an anomalous pinch can occur in ultrarelativistic electron-electron or positron-positron beam interaction, caused by the combined interplay of collective beam motion (…
Design Initiative for a 10 TeV pCM Wakefield Collider
Spencer Gessner, Jens Osterhoff, Carl A. Lindstrøm +198
This document outlines a community-driven Design Study for a 10 TeV pCM Wakefield Accelerator Collider. The 2020 ESPP Report emphasized the need for Advanced Accelerator R\&D, and…
