The violation of Lorentz invariance is predicted by most of the theories beyond the Standard Model as string theories or quantum loop gravities. It arises as a consequence of merging the Standard Model with gravity, whose effects appear at the Planck mass scale. Therefore, the observation of the violation of Lorentz invariance (and CPT invariance) is searched as a very strong hint of physics...
Leptogenesis is an elegant scenario where the baryon asymmetry of the Universe is produced from a lepton asymmetry generated in the decays of a heavy right-handed neutrino. In this talk, I will briefly review on the novel mechanism and discuss whether we can test the scenario by current/future experiments. In the latter half of the talk, I would like to give you a concrete example of the...
The PandaX (Particle AND Astrophysical Xenon experiment) project, located at China JinPing underground Laboratory (CJPL), uses xenon Time Projection Chambers (TPC) to search for the dark matter particles as well as the Neutrinoless Double Beta Decay (NLDBD) of Xe-136 isotope. The second phase of the experiment, PandaX-II, is a 500 kg scale dual phase liquid xenon TPC and has been one of the...
