Description
Modular symmetry arises in various extensions of the Standard Model and plays an important role in particle phenomenology, particularly as a framework for flavor symmetries. In this talk, I will explore the cosmological implications of modular symmetry, with a special focus on inflationary physics. I will discuss how specific couplings between moduli and the Standard Model sector can influence inflationary dynamics and leave characteristic imprints on inflationary observables.
