The simplest extension of the standard model consists in adding one singlet scalar field which mixes with the Higgs boson. O(GeV) masses of the new scalar carry strong motivation from relaxion, dark matter and inflation models. The decay of a GeV scalar is, however, notoriously difficult to address since, at this mas...

It is shown that both the universal coupling of the rho-meson and the Kawarabayashi-Suzuki-Riadzuddin-Fayyazuddin expression for the magnitude of its coupling constant follow from the requirement that chiral perturbation theory of pions, nucleons, and rho-mesons is a consistent effective field theory.

Electroweak theory is extended to $SU_L(2)\times U_Y(1)\times U_{\phi}(1)$, where $U_{\phi}(1)$ comes from the coupling of inflaton field to Higgs field. There arises an extremely light boson, $Y_{\mu}$. We resemble it as the wavelike dark matter, $\Psi$DM, through the dynamical analysis. The interactions of $Y_{\mu}$ ...

We survey some of the recent promising developments in the search for the theory behind neutrino mass and tri-bimaximal mixing, and indeed all fermion masses and mixing. We focus in particular on models with discrete family symmetry and unification, and show how such models can also solve the SUSY flavour and CP proble...
