abstract
We study the extended colored Zee-Babu model introducing a vector-like quark and singlet scalar. The active neutrino mass matrix and muon anomalous magnetic moment are analyzed, which can be fitted to experimental data satisfying the constraints from flavor changing neutral current. Then we discuss signature of our model via vector-like quark production. In addition, the diphoton excess can be explained with the contribution from vector-like quark

A radiative neutrino mass model with leptoquarks under non-holomorphic modular $A_4$ symmetry
A modular A4 flavor symmetry applied to a two-leptoquark radiative seesaw model can reproduce observed quark and lepton data while predicting a normal neutrino mass ordering and specific ranges for Σmν and neutrinoless double beta decay.
