摘      要：Exploiting high-energy electron beams colliding into high-intensity laser pulses brings an opportunity to reach high values of the dimensionless rest-frame acceleration χ and thereby invoke processes described by strong-field quantum electrodynamics(SFQED).Measuring deviations from the results of Furry-picture perturbation theory in SFQED at high χ can be valuable for testing existing predictions,as well as for guiding further theoretical ***,such experimental measurements are challenging due to the probabilistic nature of the interaction processes,dominating signals of low-χ interactions and limited capabilities to control and measure the alignment and synchronization in such collision *** we elaborate a methodology of using approximate Bayesian computations for drawing statistical inferences based on the results of many repeated experiments despite partially unknown collision parameters that vary between *** a proof-of-principle,we consider the problem of inferring the effective mass change due to coupling with the strong-field environment.
