Revealing signals of higher-order nonlinear showers in particle-laser collisions
T. G. Blackburn, B. King, M. Samuelsson
Several high power laser facilities are reaching field strengths where leading order strong-field quantum electrodynamical (QED) processes can be measured in the non-perturbative r…

Collision parameters needed to measure polarisation-dependent nonlinear pair creation
Mathias Samuelsson, Thomas G. Blackburn
Pair creation by a ray in a high-intensity electromagnetic field (the nonlinear Breit-Wheeler process) is sensitive to the -ray polarisation. Here we study the stability r…

Nonlinear Breit-Wheeler pair production using polarized photons from inverse Compton scattering
Daniel Seipt, Mathias Samuelsson, Tom Blackburn
Observing multiphoton electron-positron pair production (the nonlinear Breit-Wheeler process) requires high-energy rays to interact with strong electromagnetic fields. In orde…
