Fundamental symmetries of nature

Abstract: The building blocks of our universe, elementary particles, obey some simple rules based on certain symmetry arguments. The most basic interactions of elementary particles can be described by the Standard Model, whose underlying symmetry structure is described by the group structure SU(3)xSU(2)xU(1). There are more symmetries--sometimes empirical, sometimes accidental--we encounter when studying elementary particles. Some of these symmetries must be broken in order for our universe to work, e.g. based on our observations matter--antimatter symmetry is not a good symmetry since we do not have any antimatter in the universe while the SM has this symmetry. I will give a broad overview of the interconnection between particle physics and symmetries and how they help us build theoretical models of our universe.
