Towards unification of lepton and quark mass matrices from double covering of modular A4 flavor symmetry
Abstract
We study quark and lepton masses and mixings in a double covering of modular A4 flavor symmetry in which we search for common solution of a single modulus τ, applying chi-square numerical analysis under the as minimum framework as possible. We have found the common region of τ within 5σ interval that is narrow in case of normal hierarchy, but not found in case of inverted hierarchy.
