Title: A three-pronged attack to uncover new physics

Speaker: Dr. Tanmoy Mondal, Osaka University, Japan

Abstract: The Standard Model (SM) of particle physics provides an elegant mathematical description of the fundamental building block for our understanding of natural phenomena. The Higgs boson, which was finally discovered in 2012 at the world’s most powerful particle collider - the Large Hadron Collider, plays a unique role in fundamental physics and gives all the known elementary particles, including itself, their masses. While this observation completes the SM picture, there is a growing appeal to look for an extension from a number of experimental results (e.g. neutrino oscillation, dark matter, baryogenesis etc.) that the SM cannot explain. So far, the experiments have not produced any undisputable signature of new physics, and we have no clear roadmap to new physics, but the Higgs boson plays a crucial role in this quest. Also, understanding the laws governing the dark matter dynamics in the Universe are undoubtedly one of the pressing questions.

In this talk, I highlight the current status regarding the exploration for physics beyond the Standard Model and what is the best we can do. I will discuss precise measurements of the observed Higgs boson to understand the Higgs sector and its extension. We will see how a bottom-up approach to understand various observed hints and anomalous results can guide experimental collaborations to investigate new physics signatures. Lastly, I will ponder on the particle nature of dark matter and strategies to uncover it.
