In a simplified model we discuss the prospects for discovering the Yukon $\phi$ in gluon-gluon fusion production, with $(t, b)$ and $(T, B)$ quarks in the loops, and decaying in the channels $\phi\rightarrow \gamma\gamma, Z\gamma$ and $\phi\rightarrow tT\rightarrow tth^0, ttZ$.

We combine $SU(5)$ Grand Unified Theories (GUTs) with $A_4$ modular symmetry and present a comprehensive analysis of the resulting quark and lepton mass matrices for all the simplest cases.

In the classic type I seesaw mechanism with very heavy right-handed (RH) neutrinos, it is possible to account for dark matter via RH neutrino portal couplings to a feebly interacting massive particle (FIMP) dark sector.
