Observation of Light-by-Light Scattering and Search for Axion-Like Particles with CMS Experiment
Light-by-light (LbL) scattering ($\gamma \gamma \rightarrow \gamma \gamma $) is a fundamental quantum mechanical process which could not be observed until recently due to its tiny cross section. By using huge photon fluxes from lead-on-lead (PbPb) ultraperipheral collisions (UPCs), the process has n...
