The Hunt for New Particles at the Large Hadron Collider: The Higgs Boson and Beyond

In the list of fundamental particles, as we know today, the electron was discovered first and the last one to be discovered was the Higgs Boson. With the discovery of the Higgs boson in 2012 at the Large Hadron Collider (LHC) at CERN, the European Particle Physics Laboratory - experimental verification of the theory of fundamental particles of the Universe, known as the Standard Model of Particle Physics (SM) - came to a conclusion. However, some big questions still remain open. What makes up dark matter (and dark energy) in the universe? What is the origin of the mass of neutrinos? What is the origin of the matter-antimatter asymmetry in the Universe? In this talk, I shall give an overview of how the Higgs discovery was made at the LHC and the hunt for new physics at the LHC since the discovery of the Higgs boson, with a focus on the searches for dark matter at the LHC. Also, I shall highlight how Machine Learning techniques have proved to be immensely useful for the searches at the LHC.
