Completing Axion Double Level Crossings
Hai-Jun Li, Wei Chao, Huai-Ke Guo +1
In this work, we present the refinement of axion double level crossings within the context of multi-axion mass mixing, specifically focusing on cases where the number of axions exc…
Axion effects on gamma-ray spectral irregularities. II: Implications of EBL absorption
Hai-Jun Li, Wei Chao, Xiu-Hui Tan +1
The extragalactic background light (EBL) plays a crucial role in the propagation of high-energy particles throughout the Universe. In this work, we explore the impact of the EBL ab…
Upper limit on the axion-photon coupling from Markarian 421
Hai-Jun Li, Wei Chao, Yu-Feng Zhou
Markarian 421 is a well-known nearby BL Lac blazar at the redshift . Many previous works were investigated to constrain the axion-photon coupling from its TeV gamma-ray ob…
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…
