13. Spin-3/2 Dark Matter in simple s or t channel models

16/12/2019 14:00

We consider possible spin-3/2 dark matter (DM) particles which can either interact with the Standard Model (SM) fermions through a vector mediator in the s-channel, or with SM quarks through the exchange of a charged and coloured scalar or vector mediator in a simple t-channel model. Constraints on the parameter spaces of these models are investigated, drawing from the observed relic...

8. Neutrino self-interaction in the signals from blazar TXS 0506+056

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 $E_{\gamma }\in ({10}^{-1}\mathrm{e}\mathrm{V},{10}^2\mathrm{G}\mathrm{e}\mathrm{V})$, the predicted neutrino flux is too small to be consistent with the IceCube observation at $E_{\nu }\simeq 300\mathrm{T}\mathrm{e}\mathrm{V}$. We show that...

4. Composite GUT

Seung Joon Lee (Korea University)

18/12/2019 09:00

I will talk about coupling unification in a composite Higgs model, and also dark matter coming out of this.

7. Higgs as inflaton

Seong Chan Park (Yonsei University)

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.
