A Class of Exact Single-Field Inflationary Solutions beyond Slow Roll

Jia-Wei Zhang, Bai-Cian Ke, Yao Yu +2

We construct exact solutions for single-field inflaton dynamics without invoking the slow-roll approximation. A suitable change of variables reduces the background equation to an A…

Angular and invariant-mass observables in the four-body Higgs decay

Han Zhang, Bai-Cian Ke, Yao Yu +2

We study the angular distribution of the Higgs boson decay with . Due to the presence of two undetected ne…

Power-Law Inflation Survives Observational Constraints

Yao Yu, Wen-Zhang Feng, Hong-Song Xie +2

Power-law inflation has stood as a classical model in inflationary cosmology since the early 1980s, prized for its exact analytical solutions and ability to naturally resolve the B…

A phenomenological estimate of rescattering effects in

Yao Yu, Hai-Bing Fu, Han Zhang +1

The measurements in penguin-dominated decays are widely recognized as a powerful test for searching for New Physics by studying the deviation from theoretical estimations…

Novel Model-Independent Approach to Explore New Physics in Five-body Semileptonic Decays

Yao Yu, Hong-Song Xie, Han Zhang +3

Substantial contribution of the tensor current in semileptonic decays is regarded as a clear signal for new physics. In this work, we propose a model-independent approach to unambi…

Five-body Semileptonic Decays

Yechun Yu, Han Zhang, Bai-Cian Ke +3

Our main objective is to derive the decay rate for the semileptonic decays , where represents a vector particle. In these decays, the vector p…
