Probing $D_{s}^{+} \to η^{(')} ℓ^{+} ν_{ℓ}$ semileptonic decay within LCSR under chiral heavy quark effective field theory

Ruiyu Zhou, Hai-Bing Fu, Yi Zhang +1

Motivated by the successful application of Heavy Quark Effective Field Theory in describing decays from heavy to light mesons, this work explores its applicability to the semilepto…

Exploring the Impact of Dissipation Coefficient in Warm Higgs Inflation

Wei Cheng, Xue-Wen Chen, Ruiyu Zhou +4

In this study, we conducted a detailed analysis of the core parameter of Warm Higgs Inflation (WHI) $-$ the dissipation coefficient ( $Q$ ). As a crucial parameter in the warm inflat…

Dark matter production accompanied by gravitational wave signals during cosmological phase transitions

Shuocheng Xu, Ruiyu Zhou, Wei Cheng +1

We investigate the temperature-dependent production of feebly interacting massive dark matter particle (FIMP DM) within a $Z_{2}$ model, incorporating two $Z_{2}$ -odd scalar fields. In…
