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…

Exclusive Determination of $∣ V_{c b} ∣$ from Semileptonic Decays $B \to D^{(*)} ℓ ν_{ℓ}$

Xue-Wen Chen, Bo-Yan Cui, Jia-Wei Zhang +2

We present an updated exclusive determination of the CKM matrix element $|V_{cb}|$ from the semileptonic decays $B\to D^{(*)}\ell\barν_{\ell}$. Our analysis combines the latest…

Angular and invariant-mass observables in the four-body Higgs decay $h \to ℓ ν ˉ_{ℓ} ℓ ˉ^{'} ν_{ℓ^{'}}$

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

We study the angular distribution of the Higgs boson decay $h \to ℓ ν ˉ_{ℓ} ℓ ˉ^{'} ν_{ℓ^{'}}$ with $ℓ \neq = ℓ^{'}$ . Due to the presence of two undetected ne…
