Non-linear Breit-Wheeler pair production in collisions of bremsstrahlung $\gamma -$quanta and a tightly focussed laser pulse

Alina Golub, Selym Villalba-Chávez, Carsten Müller

Experimental efforts toward the detection of the nonperturbative strong-field regime of the Breit-Wheeler pair creation process plan to combine incoherent sources of GeV $\gamma$ quanta…
