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…

Analysis of the Pion Electromagnetic Form Factor with Next-to-Next-to-Leading Order QCD Corrections

Sheng-Quan Wang, Zuo-Fen Liao, Jian-Ming Shen +5

NNLO QCD corrections for the pion electromagnetic form factor at large momentum transfer have been recently performed in [Phys. Rev. Lett. 132, 201901 (2024); Phys. Rev. Lett. 134,…

Quasi-two-body decays $B \to P f_{0} (500) \to P π^{+} π^{-}$ in the perturbative QCD approach

Jia-Wei Zhang, Bo-Yan Cui, Xing-Gang Wu +2

In this paper, we study the quasi-two-body decays $B \to P f_{0} (500) \to P π^{+} π^{-}$ [with $P = (π, K, η, η^{'})$ ] within framework of perturbative QCD (PQCD) factorization approach.…

Improved analysis of double $J / ψ$ production in $Z$ -boson decay

Guang-Yu Wang, Xing-Gang Wu, Xu-Chang Zheng +2

In this paper, we present an improved calculation for the decay rate of the rare $Z$ -boson decay into $J / ψ + J / ψ$ . This decay is dominated by the photon fragmentation mechanism, i.e…
