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…
Testing Non-Standard Neutrinos in Purely Leptonic Lepton Decays
Han Zhang, Bai-Cian Ke, Yao Yu
We propose a method to probe sterile neutrinos using polarization observables in the purely leptonic decays . By analy…
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…
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…
