Kristof Schmieden - Measuring light-by-light scattering at ATLAS
RTG Seminar on Wednesday, November 6th, 2019
The process of two photons scattering off each other is predicted since the 1930ies. Yet only recently, in 2016, the first experimental evidence of this process was published by the ATLAS collaboration, followed by the observation released this year. The measurement was performed using PbPb collisions from the LHC, recorded with the ATLAS detector in 2018. In this talk I will detail the analysis, highlight some of the experimental challenges and discuss the sensitivity to physics beyond the standard model.
