$O (α^{3} α_{s})$ Study on the yields and polarizations of $J / ψ (Υ)$ within the framework of non-relativistic QCD via $γ γ \to J / ψ (Υ) + γ + X$ at CEPC

Zhan Sun, Xiong Deng, Hai Bing Fu

Within the framework of the non-relativistic QCD (NRQCD), we make a systematical study of the yields and polarizations of $J / ψ$ and $Υ$ via $γ γ \to J / ψ (Υ) + γ + X$ in photon-photon coll…

QCD Corrections to the Color-singlet $J / ψ$ Production in Deeply Inelastic Scattering at HERA

Zhan Sun, Hong-Fei Zhang

We present the first study of the QCD corrections to the color-singlet (CS) $J / ψ$ production in deeply inelastic $e p$ scattering at HERA. The $K$ -factor ranges from $0.85$ to $2.38…

QCD leading order study of the $J / ψ$ leptoproduction at HERA within the nonrelativistic QCD framework

Zhan Sun, Hong-Fei Zhang

As indicated in our previous paper (Phys.Rev.D96.034002), the existing literatures studying the $J / ψ$ production in deeply inelastic scattering (DIS) in collinear factorization are…

Is the colour-octet mechanism consistent with the double $J / ψ$ production measurement at B-factories?

Yu Feng, Zhan Sun, Hong-Fei Zhang

Double $J / ψ$ production in $e^{+} e^{-}$ collisions involving colour-octet channels are evaluated up to order $α^{2} α_{s}^{3}$ . Having implemented the variation of the parameters ( $m_{c}$ , $μ_r…

The leptonic current structure and azimuthal asymmetry in deeply inelastic scattering

Hong-Fei Zhang, Zhan Sun

We present a compact form of the leptonic currents for the computation of the processes involving an initial virtual boson (photon, $W^{\pm}$ or $Z_{0}$ ). For deeply inelastic scatte…
