Report on progress in physics: observation of the Breit-Wheeler process and vacuum birefringence in heavy-ion collisions
{{output}}
This report reviews the effort over several decades to observe the linear Breit-Wheeler process (γγ→e+e-) and vacuum birefringence (VB) in high-energy particle and heavy-ion collider experiment. This report, motivated by the STAR collaboration's recent obse... ...
