$C P T$ Violating Electrodynamics and Chern-Simons Modified Gravity

Mingzhe Li, Yi-Fu Cai, Xiulian Wang +1

The electrodynamics with a Chern-Simons term $p_{μ} A_{ν} F^{μν}$ violates Lorentz and $C P T$ symmetries with a non-vanishing $p_{μ}$ . For a fixed vector $p_{μ}$ , in this paper we…

Cosmic Ray Positrons from Cosmic Strings

Robert Brandenberger, Yi-Fu Cai, Wei Xue +1

We study the spectrum of cosmic ray positrons produced by a scaling distribution of non-superconducting cosmic strings. In this scenario, the positrons are produced from the jets w…

An SO(10) GUT Model with $S 4$ Flavor Symmetry

Yi Cai, Hai-Bo Yu

We present a supersymmetric grand unification model based on SO(10) group with $S 4$ flavor symmetry. In this model, the fermion masses are from Yukawa couplings involving $10$ …
