Category: ACFI Seminar

I present the search for heavy triboson production, specifically targeting the production of WWW, WWZ, WZZ and ZZZ processes in multileptonic final states with 137/fb of data collected by the CMS detector during Run II of the LHC at a center-of-mass energy 13 TeV.  The search is performed in final states with three, four, five, and six leptons (electrons or muons), or with two same-charge leptons plus two jets. During this seminar, the physics behind the triboson process will be motivated, including a discussion on the difficulties to experimentally measure it. Then, the analysis strategy aimed to observe tribosons will be shown and the results will be presented. At the end, an outlook on future triboson studies and extensions towards probing the standard model and potential new physics will be given.
