Scouting trigger and search for dark photon in dimuon channel in CMS — Thomas Hebbeker and •Swagata Mukherjee — III. Physikalisches Institut A, RWTH Aachen University, Aachen

After several years of running of the LHC, new physics has not been found yet. It is high time to focus on the difficult corners of the phase space. Data scouting is one such attempt. This special data flow, based on event-size reduction rather than event filtering, will be reviewed in this talk. Scouting data is useful to perform searches for low mass resonances, where nominal triggers have reduced or zero sensitivity. A new search for dark-photons in the dimuon channel has been designed in CMS, which utilises dimuon scouting data for low mass. An intriguing possibility that the dark matter might interact via a new dark force, felt only feebly by standard model particles, has recently motivated a worldwide effort to search for dark forces. A particularly compelling dark-force scenario is that of a dark photon, which has small couplings to standard model particles via kinetic mixing with the ordinary photon. This new search will be discussed in this talk.
