Relic Density of Asymmetric Dark Matter with Breit-Wigner Enhancement
Fangyu Liu, Hoernisa Iminniyaz, Qiquan Li
The Breit-Wigner Enhancement mechanism provides a novel interpretation for the ``enhancement factor'' derived from data of the PAMELA, ATIC, and PPB-BETS experiments, and we furthe…
Constraints on Asymmetric Dark Matter Self Annihilation Cross Sections
Qiquan Li, Hoernisa Iminniyaz, Fangyu Liu
We investigate the evolution of the relic density for asymmetric dark matter incorporating self annihilation processes in both the shear-dominated universe and Gauss-Bonnet branewo…
Non-standard cosmological scenarios, Sommerfeld enhancement and asymmetric dark matter
Reyima Rashidin, Fangyu Liu, Hoernisa Iminniyaz
We discuss the relic density of asymmetric dark matter with long-range interactions in non-standard cosmological scenarios where the extra cosmic energy is introduced. The Hubble e…
Constraints on non-standard cosmological models from Planck data
Hoernisa Iminniyaz, Alimasi Aisha, Fangyu Liu
We review the relic density of dark matter in the non-standard cosmological scenarios which includes kination models, brane world cosmology and shear dominated universe. Then we us…
Constraints on Asymmetric Dark Matter Self Annihilation Cross Sections in Non-standard Cosmological Scenarios
Fangyu Liu, Hoernisa Iminniyaz
We investigate the relic abundance of asymmetric dark matter in the non-standard cosmological scenarios when the annihilation cross section includes self annihilations. Here we dis…
