Even though conventional leptonic or lepto-hadronic models of blazar successfully explain the observed electromagnetic component of the flaring signal from the Blazar TXS 0506+056 in a large range of energy window $E_\gamma \in (10^{-1}{\rm eV}, 10^2~{\rm GeV})$, the predicted neutrino flux is too small to be consistent with the IceCube observation at $E_\nu \simeq 300~{\rm TeV}$. We show that...
I will discuss the recent update about the Higgs inflation where the Higgs field is regarded as the inflaton field. The unitarity issue, (p)re-heating issue and the potential production of primordial black hole will be discussed.
I will talk about coupling unification in a composite Higgs model, and also dark matter coming out of this.
We point out that two models that reconcile the neutron lifetime anomaly via dark decays of the neutron, also predict dark matter-neutron ($\bar{\chi}-n$) annihilation that may be observable in neutron-antineutron oscillation and proton decay searches at Super-Kamiokande, Hyper-Kamiokande and DUNE. We study signatures of $\bar{\chi}n\to \gamma\pi^0$~(or multi-$\pi^0$) and $\bar{\chi}n\to...
