Axion-like Dark Matter from the Type-II Seesaw Mechanism
Wei Chao, Mingjie Jin, Hai-Jun Li +1
Although axion-like particles (ALPs) are popular dark matter candidates, their mass generation mechanisms as well as cosmic thermal evolutions are still unclear. In this letter, we…

The implications of the axion like particle from the Fermi-LAT and H.E.S.S. observations of PG 1553+113 and PKS 2155-304
Junguang Guo, Hai-Jun Li, Xiao-Jun Bi +2
We investigate the axion like particle (ALP)-photon oscillation effect in the high energy -ray spectra of PG 1553+113 and PKS 2155-304 measured by Fermi-LAT and H.E.S.S.. The ch…
