DOI: 10.1007/jhep03(2025)093

Abstract: We discuss the stabilization of multiple moduli by utilizing Siegel modular forms in the framework of Sp(2g, ℤ) modular invariant theories. For a generic modular- and CP-invariant scalar potential, we find that CP-conserving fixed points… read more here.

DOI: 10.1007/jhep04(2025)041

Abstract: Potentials in cosmological inflation often involve scalars with trans-Planckian ranges. As a result, towers of states become massless and their presence pushes the fundamental scale not to coincide with MP but rather with the species… read more here.

DOI: 10.1088/1475-7516/2024/10/016

Abstract: We propose new classes of inflation models based on the modular symmetry, where the modulus field τ serves as the inflaton. We establish a connection between modular inflation and modular stabilization, wherein the modulus field… read more here.

DOI: 10.1103/physrevlett.130.101801

Abstract: We analyze a large set of modular invariant models of lepton masses and mixing angles, pointing out that many of them prefer to live close to the self-dual point τ=i. We show that in the… read more here.
