24. Astrophysical territory of multi-component boosted dark matter

Seodong Shin (Jeonbuk National University)

28/11/2021, 09:00

I will talk about the effects of multi-component boosted dark matter in various astrophysical phenomena. Also, its effect to various neutrino experimental and dark matter direct detection experimental results

25. Millicharged Particles and Dark Matter indirect detection

Meshkat Rajaee (Jeonbuk National University)

28/11/2021, 09:30

Various alleged indirect dark matter search signals, such as the 511 keV line from galaxy center or the PAMELA/AMS02 signal, are often challenged by the absence of corresponding signal from dwarf galaxies and/or from the absence of an impact on CMB through delayed recombination. We propose a novel scenario to explain 511 keV signal, that can avoid these bounds based on the decay of dark...

28. Paths to proton stability in grand unification

Oleg Popov (KAIST)

28/11/2021, 10:00

We explore scenarios within grand unification in which proton decay can be suppressed and possibly eliminated due to novel embeddings of the Standard Model matter fields into irreducible representations of the grand unified group and residual symmetries. The scenarios are based on an $SU(7)$ gauge group, in which the matter fields are embedded within an anomaly-free set of fields that can be...

27. Models for flavor anomalies and dark matter

Pyungwon Ko (KIAS)

28/11/2021, 11:00

I will discuss a few models that can accommodate flavor anomalies as well as dark matter of the universe.

26. Muonphilic Dark Matter explanation of gamma-ray galactic center excess

Chih-Ting Lu (KIAS)

28/11/2021, 12:00

The Galactic center gamma-ray excess (GCE) is a long-standing unsolved problem. One of candidate solutions, the dark matter (DM) annihilation, has been recently tested with other astrophysical observations, such as AMS-02 electron-positron spectra, Fermi Dwarf spheroidal galaxies gamma ray data, and so on. It has been claimed that only the DM annihilation to a muon-pair, namely muonphilic DM,...
