helicity form factors and the decays
Wei Cheng, Yi Zhang, Long Zeng +2
In this paper, we calculate the helicity form factors (HFFs) up to twist-4 accuracy by using the light-cone sum rules (LCSR) approach. After extrapolating those HFFs t…
Axion-like particle inflation and dark matter
Wei Cheng, Ligong Bian, Yu-Feng Zhou
In this paper, we propose a generalized natural inflation (GNI) model to study axion-like particle (ALP) inflation and dark matter (DM). GNI contains two additional parameters $(n_…
