"Exploring Beyond the Standard Model with Lattice QCD" While the Standard Model (SM) of particle physics has been enormously successful in describing the world around us, there still remain many important and unanswered questions requiringBeyond the SM (BSM) physics. One way to experimentally probe the limits of the SM is to search for potential violations of its fundamental symmetries by utilizing properties of special atomic nuclei which enhance these rare events. Connecting experimental signals from nuclear environments to a particular BSM model requires the numerical solution of Quantum Chromodynamics (QCD), a cornerstone of the SM which governs the nuclear interactions. In this talk I will discuss the use of Lattice QCD as a tool for numerically calculating matrix elements relevant for experimental BSM searches. I will use neutrinoless double beta decay, which, if observed, could offer an explanation for the matter-antimatter asymmetry of the universe, as a key example.
