Research Interest

High energy physics is driven by the exploration of the standard model (SM) of particle physics, a theoretical framework that successfully describes the known fundamental particles and their interactions. The SM includes the electromagnetic, weak, and strong forces, and it has been validated through decades of experiments, culminating in groundbreaking discoveries like the Higgs boson in 2012. According to the SM, matter is composed of elementary particles such as quarks and leptons, which interact through force-carrier particles (gauge bosons) like photons, gluons, and W/Z bosons. The model also explains the Higgs mechanism, which gives mass to many particles. However, the SM is not a complete theory of the universe. Despite its success, it leaves many unanswered questions, such as the nature of dark matter and dark energy, the reason for the masses of neutrinos, and why gravity is not included in its framework. These gaps in our understanding have motivated the search for physics beyond the Standard Model.

The search for physics beyond the Standard Model is one of the most exciting frontiers in modern science. It involves experiments at high-energy particle colliders like the Large Hadron Collider (LHC), as well as precision measurements, astrophysical observations, and theoretical work. While the Standard Model remains our best description of the subatomic world, the quest for new physics continues to push the boundaries of knowledge, potentially unveiling new realms of the universe and offering profound insights into the nature of reality itself.

Therefore, this is what I am doing at the CMS experiment of the LHC. I am looking for hints of physics unexplained by the SM by either studying the properties of known particles or by directly searching for new physics. In particular, I am studying properties of single boson and diboson production modes, in either inclusive or exclusive topologies. They are important on their own, but they may also be coming from decays from beyond the SM particles.
