Search for Anomalous Triple Gauge Couplings in the Semileptonic WW and WZ Decays Using the CMS Experiment — •Muhammad Ansar Iqbal, Matthias Mozer, Thomas Müller, and Ivan Shvetsov — Institut für Experimentelle Teilchenphysik (ETP), Karlsruher Institut für Technologie (KIT)

One of the best ways to search for physics beyond the Standard Model (SM) is in the framework of the Effective Field Theory. The Large Hadron Collider (LHC) at CERN with 13 TeV center of mass energy in Run II has opened new doors for such novel searches. We work with the Compact Muon Solenoid (CMS) experiment of the LHC on an analysis which focuses on anomalous triple gauge couplings (aTGC) in the electroweak sector. The analysis deals with the WW/WZ final states in the semileptonic decay channel, where the hadronically decaying vector boson is reconstructed in the boosted regime.

In this talk we present the on-going analysis with the steps involved in order to model our backgrounds and extraction of signal. We discuss the statistical techniques important for the analysis and show various results and plots we have for 36 fb⁻¹ of 2016 data. We also present the limits on aTGC parameters already obtained with a previous iteration of the analysis.
