Abstract Recently, the worldwide pulsar timing array(PTA) collaborations, such as the Chinese Pulsar Timing Array (CPTA), the European PulsarTiming Array (EPTA), the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) and the Park

Abstract The NANOGrav collaboration has published a suspected stochastic gravitational wave (GW) background signal in its analysis of 12.5 years PTA data, so in this work, we investigate the possibility to explain the signal by the inflationary model

Abstract We investigate the possibility of inducing the gravitational waves (GWs) with double peak energy spectrum from primordial scalar perturbations in inflationary models with three inflection points. Here the inflection points can be generated f

Abstract In the model of the inflaton nonminimal coupling to the Gauss–Bonnet term, we discuss the constant-roll inflation with constant $$\epsilon _1$$ ϵ 1 , constant $$\epsilon _2$$ ϵ 2 and constant $$\eta _H$$ η H , respectively, with the add

We perform an analysis on B0–B¯0 mixing in the extension of the minimal supersymmetric standard model where baryon and lepton numbers are local gauge symmetries (BLMSSM) by using the effective Hamiltonian method. And the constraint of a 125 GeV Hi

The on-shell renormalization scheme for the electroweak theory is well studied in the standard model(SM), but a consistent on-shell renormalization scheme for the minimal supersymmetric standard model(MSSM) is still unknown. In MSSM, we study the on-

In this work, we investigate constraints on the reheating era within the framework of supersymmetry flat direction inflation. We express the e-folding number during reheating Nre and the final reheating temperature Tre as functions of the scalar spec

We study the production of gravitational waves from primordial scalar perturbations in double-inflection-point inflation, in which one of the inflection points leads to a primordial power spectrum consistent with CMB observations at large scales and

Survival strategies of plants to adapt to environmental stress include avoidance and tolerance. These strategies were investigated in the wetland sedge Carex brevicuspis (Cyperaceae) to determine the plasticity of its response to flood and drought. I

We propose a double inflection points inflationary model in supergravity with a single chiral superfield. Such a model allows for the generation of primordial black holes (PBHs) at small scales, which can account for a significant fraction of dark ma
