We study the electroweak phase transition in three scalar extension models beyond the Standard Model.Assuming new scalars are decoupled at some heavy scale, we use the covariant derivative expansion method to derive a...

Recently, many new dwarf spheroidal satellites(dSphs) have been discovered by the Dark Energy Survey(DES). These dSphs are ideal candidates for probing for gamma-ray emissions from dark matter(DM) annihilation.H...

Recently, a novel idea [1] has been proposed to relax the electroweak hierarchy problem through the cosmological inflation and the axion periotic potential. Here, we further assume that only the attractive inflation i...

Gravitational waves (GW), which were predicted by Einstein in 1916 based on the classical theory of General Relativ- ity (GR), were recently detected by LIGO [1]. This break- through is expected to initiate a nove...

Recently BICEP2 collaboration has announced the detection of the primordial gravitational waves at high confidence level. In light of the results of B-modes power spectrum from BICEP2 and using the based ACDM, a const...
