TL;DR: In this article, the authors measured an energy loss in the postcollision electron spectrum that is correlated with the detected signal of hard photons (gamma rays), consistent with a quantum description of radiation reaction.

TL;DR: Substantial energy loss in an electron beam passing through a high-intensity laser provides clear evidence of the radiation reaction, shedding light on how electrons interact with extreme electromagnetic fields.

TL;DR: In this article, the authors measured an energy loss in the post-collision electron spectrum that is correlated with the detected signal of hard photons, consistent with a quantum (stochastic) description of radiation reaction.

TL;DR: In this article, the authors reported experimental evidence of strong radiation reaction, in an all-optical experiment, during the propagation of highly relativistic electrons (maximum energy exceeding 2 GeV) through the field of an ultra-intense laser (peak intensity of $4\times10^{20}$ W/cm$^2$).

TL;DR: The first experimental observation of a current-driven instability developing in a quasineutral matter-antimatter beam is reported, suggesting the existence of such long-lived magnetic fields can be related to analog astrophysical systems, such as those prevalent in lepton-dominated jets.
