$γ W$ -exchange correction beyond the forward-angle limit in neutron $β$ decay

Hui-Yun Cao, Hai-Qing Zhou

In this work, we discuss the $γ W$ -exchange contributions in neutron $β$ decay with an elastic intermediate state, beyond the forward-angle limit (FAL). By decomposing the one- $W$ -e…

$γ Z$ -exchange contribution in elastic $e p$ scattering by perturbative QCD

Qian-Qian Guo, Hui-Yun Cao, Hai-Qing Zhou

In this study, we calculate the $γ Z$ -exchange contribution to elastic $e p$ scattering at large momentum transfer within perturbative QCD. We present analytical expressions for the…

$γ W$ -exchange contributions in neutron $β$ decay in the forward-angle limit

Hui-Yun Cao, Hai-Qing Zhou

In this work, the contributions from $γ W$ -exchange in neutron $β$ decay are estimated at the amplitude level. Using a general form for the electromagnetic (EM) form factors (FFs) o…

Recoil contributions in neutron beta decay and their corrections to the correlation coefficients

Hui-Yun Cao, Hai-Qing Zhou

In this work, the recoil corrections to the correlation coefficients in the neutron beta decay with polarized neutron and electron are evaluated to order O(m_n^-2) in the Born appr…

Two-photon exchange effects in $e^{+} e^{-} \to π^{+} π^{-}$ at small $s$

Zhong-Hua Zhao, Hui-Yun Cao, Hai-Qing Zhou

In this work, the two-photon-exchange (TPE) effects in $e^{+} e^{-} \to π^{+} π^{-}$ at small $s$ are discussed within a hadronic model. In the limit $m_{e} \to 0$ , the…

Exact Relations for Two-Photon-Exchange Effect in Elastic $e p$ Scattering by Dispersion Relation and Hadronic Model

Hui-Yun Cao, Hai-Qing Zhou

The two-photon-exchange (TPE) effect plays a key role to extract the form factors (FFs) of the proton. In this work, we present some exact properties on the TPE effect in the elast…

Two-Photon-Exchange effects in $e p \to e n π^{+}$ and their corrections to separated cross sections $σ_{L,T,LT,TT}$ at small $- t$

Hui-Yun Cao, Hai-Qing Zhou

In this work, the two-photon-exchange (TPE) effects in $e p \to e n π^{+}$ at small $- t$ are discussed within a hadronic model. Under the pion dominance approximation the TPE con…
