Particle Physics Seminar

Abstract: The collection of a large dataset at the Large Hadron Collider (LHC) allows for the exploration of rare processes predicted by the Standard Model of Particle Physics (SM). In this talk I will focus on the observation of triboson production with data collected by the CMS experiment at a center of mass energy of 13 TeV using the complete Run II dataset. Triboson events are rare and feature novel topologies. I will provide an overview of the analysis that led to the first observation of tribosons at the LHC and discuss its prospects as we head toward the high luminosity-LHC. Given the absence of any significant sign of new physics at the LHC, an effective field theory (EFT) approach which posits that the source of new physics are heavy fields beyond our current reach, can be used to indirectly look for new physics. I will state how the newly observed triboson processes can be used as a probe for new physics using the EFT framework. Additionally, I will talk about detectors of the future and their role in realizing the precision era of the LHC
