Research Projects

The Standard Model of particle physics describes the fundamental interaction among visible particles, with the Higgs boson discovered at the Large Hadron Collider in 2012. However, observations and theoretical shortcomings suggest that there is something beyond the Standard Model, including dark matter, dark energy, neutrino oscillation, matter-antimatter asymmetry, and the strong CP problem. Particle physicists often develop models that extend the Standard Model to explain anomalies in experimental observations and answer burning questions in particle physics. This research project aims to study exotic particles and their interactions as a result of new theories beyond the Standard Model. Current experiments, such as the Large Hadron Collider, look for simplified scenarios, but some theoretical frameworks can build models where nonstandard interactions among exotic particles exist. This approach, which is relatively new in collider phenomenology, could address cases at the Large Hadron Collider experiment and future colliders. Exotic particles may emerge as a pseudo-Nambu Goldstone boson or global symmetry breaking, explaining dark matter relic density and matter-antimatter asymmetry. Exotic fermions could also explain the boosted dark matter scenario, favored by recent direct detection experiments. The low energy observables of the theory will have an imprint on the symmetry breaking scale at much higher energy levels, constrained by cosmological observations. Studying the correlation between symmetry breaking scale and the Electroweak scale will enrich the future of particle physics at collider experiments and explain cosmological observations.
