Two-Loop QCD Corrections to C even Bottomonium Exclusive Decays to Double $J / ψ$

Yu-Dong Zhang, Xiao-Wei Bai, Feng Feng +2

In the framework of nonrelativistic QCD (NRQCD) factorization, we compute both the polarized and the unpolarized decay widths for the processes $η_{b} (χ_{b J}) \to J / ψ J / ψ$ , accurate up…

Electromagnetic and hadronic decay of fully heavy tetraquark

Wen-Long Sang, Tao Wang, Yu-Dong Zhang +1

In this study, we compute the electromagnetic and hadronic decay widths of the S-wave fully heavy tetraquark $T_{4 Q}$ ( $Q = c$ or $b$ ) at lowest order in $α_{s}$ and $v$ , in the framew…

$Z$ boson radiative decays to a $S$ -wave quarkonium at NNLO and NLL accuracy

Wen-Long Sang, De-Shan Yang, Yu-Dong Zhang

Within the framework of nonrelativistic QCD (NRQCD) factorization formalism, we compute QCD next-to-next-to-leading order (NNLO) corrections to the helicity amplitudes as well as t…
