Axion limits from the 10-year gamma-ray emission 1ES 1215+303
Hai-Jun Li, Wei Chao, Yu-Feng Zhou
We present the limits on photon to axionlike particle (ALP) coupling from the 10-year period observations of the TeV BL Lacertae blazar 1ES 1215+303 (with redshift ). The…

Majorana Majoron and the Baryon Asymmetry of the Universe
Wei Chao, Ying-Quan Peng
The spontaneous breaking of the global lepton number, an accidental symmetry in the Standard Model of particle physics, results in a massless goldstone boson, the Majoron, which ca…

Light QCD Axion Dark Matter from Double Level Crossings
Hai-Jun Li, Ying-Quan Peng, Wei Chao +1
The even light QCD axion called the axion can both solve the strong CP problem and account for the dark matter (DM). We point out that the single and double level…
