Ping-Kai Hu


Greeting!

I am Ping-Kai Hu, currently a PhD candidate working on theoretical physics at UCLA.

My research interests are in the area of high energy physics, especially neutrino physics, dark matter, and a variety of topics in cosmology. Recently, I try to explore a new scenario for cosmic rays with my advisor Alexander Kusenko.

By the way, this website is still under construction.

Dark Cosmic Rays

The origin of ulltra-high-energy cosmic rays is still not clear. There are two different kinds of approaches to generate cosmic rays with high energy: “bottom-up” and “top-down”.

The approach of “bottom-up” is to accelerate charged particles by electromagnetic fields. It requires the mechanism like Fermi acceleration to boost particles from low energy to high energy. The alternative “top-down” approach is to generate high-energy particles by heavy-particle decays or pair annihilations, in which case we need heavy particles beyond the Standard Model.

How about we consider a model beyond the Standard Model, but still use the “bottom-up” approach? This idea leads us to the scenario of “dark cosmic rays”.

To realise the scenario, what we need is just a long-ranged force in the dark sector. The simplest way is to introduce an U(1) gauge symmetry ...
