Quark and lepton flavor model with leptoquarks in a modular $$A_4$$ symmetry
Quark and lepton flavor model with leptoquarks in a modular $$A_4$$ symmetry
We propose a quark-lepton model via leptoquarks and modular $A_4$ symmetry. Since the neutrino mass is induced at one-loop level mediated by down quarks as well as leptoquarks, we have to explain lepton and quark masses and mixings with a single modulus $\tau$. Here, we find predictions for lepton and …
