CMS Phase-2 Muon Trigger Upgrade

Since I joined CMS, I have also been involved in the Level-1 Trigger project. The CMS trigger and data acquisition system, one of the most complicated electronic, readout and event selection systems ever built in particle physics, underwent a major upgrade in 2016 for Run II and Run III, to handle twice as high energy and four times as high luminosity as in Run I.

Search for the charm quark Yukawa coupling

Since the scrutiny of the Run-II sample did not yield any signs of new physics, my interest turned to the highest priority in the field, as stated clearly in the 2020 update of the European Strategy for Particle Physics: the most in-depth possible understanding of the Higgs boson. Two Higgs couplings are currently the biggest open questions in the SM scalar sector: its couplings to fermions and its self-coupling. The coupling to fermions has no dynamic mechanism behind it and a seemingly arbitrary strength, expressed through a Yukawa coupling which is different for each fermion.

Searches for new physics using advanced machine learning

Coming from a previous-generation collider experiment, CDF, with a lower energy and luminosity reach, I was intrigued by the potential of CMS for new physics searches using the Run-II dataset, collected during 2016-2018, of nearly two times the energy and five times the luminosity of the Run-I sample from 2009-2012. I joined the Innovative Training Network (ITN) “Advanced Multivariate Analyses for New Physics Searches” (AMVA4NewPhysics) as the PI of the Institute of Accelerating Systems and Applications (IASA), one of the nodes of the ITN.
