Impact of laser polarization on q-exponential photon tails in non-linear Compton scattering
B. Kampfer, A. I. Titov
Non-linear Compton scattering of ultra-relativistic electrons traversing high-intensity laser pulses generates also hard photons. These photon high-energy tails are considered for…

We study the non-linear Breit-Wheeler process in the interaction of linearly polarized probe photons () with a linearly polarized laser be…
Comparative analysis of , , and scattering lengths from A2, CLAS, and GlueX threshold measurements
Igor Strakovsky, Lubomir Pentchev, Alexander Titov
The high accuracy -meson photoproduction data from the CLAS experiment in Hall~B of Jefferson Laboratory allow us to determine the near-threshold total cross section of the $γp\…
