Optimized QCD two-loop correction to exclusive double production at B factories
Wen-Long Sang, Feng Feng, Yu Jia +3
We report the calculation of the process up to next-to-next-to-leading order (NNLO) at a center-of-mass (CM) energy of GeV. We employ an impro…
Two-loop QCD corrections to Higgs radiative decay to vector quarkonium
Yu Jia, Zhewen Mo, Jia-Yue Zhang
The exclusive production of through Higgs boson radiative decay may serve a clean channel to extracting the charm quark Yukawa coupling. We calculate the two-loop QCD correct…
Hard-scattering approach to strongly hindered electric dipole transitions between heavy quarkonia
Cai-Ping Jia, Yu Jia, Junliang Lu +2
The conventional wisdom in dealing with electromagnetic transition between heavy quarkonia is the multipole expansion, when the emitted photon has a typical energy of order quarkon…
Photoproduction of fully charmed tetraquark at electron-ion colliders
Feng Feng, Yingsheng Huang, Yu Jia +3
In this work, we investigate the inclusive photoproduction of the -odd, -wave fully charmed tetraquark at electron-ion colliders within the nonrelativistic QCD (NRQCD) factor…
Optimized correction to exclusive double production at factories
Wen-Long Sang, Feng Feng, Yu Jia +3
The failure of observing the events at factories to date is often attributed to the significant negative order- correction. In this work we compute t…
Inclusive production of fully-charmed tetraquarks at LHC
Feng Feng, Yingsheng Huang, Yu Jia +3
The resonance, originally discovered by the \texttt{LHCb} collaboration and later confirmed by both \texttt{ATLAS} and \texttt{CMS} experiments, has sparked broad interes…
Soft pattern of Rutherford scattering from heavy target mass expansion
Yu Jia, Jia-Yue Zhang
We investigate the soft behavior of the tree-level Rutherford scattering process. We consider two types of Rutherford scattering, a low-energy massless point-like projectile (say,…
New Physics Opportunities in Triangle Singularity
Yu Gao, Yu Jia, Yugen Lin +1
We show that loop-induced processes involving new physics particles can readily satisfy Landau Equation and trigger triangular singularities at high energy colliders, leading to fu…
Three-loop QCD corrections to the decay constant of
Feng Feng, Yu Jia, Zhewen Mo +3
Within the framework of nonrelativistic QCD (NRQCD) factorization, we compute the three-loop QCD corrections to the decay constant of . We reconstruct the analytical expressio…

Feng Feng, Yu Jia, Zhewen Mo +3
Within the nonrelativistic QCD (NRQCD) factorization framework, we compute the order- perturbative corrections to the leptonic decay of the and with high numerical…
Photoproduction of C-even quarkonia at EIC and EicC
Yu Jia, Zhewen Mo, Jichen Pan +1
The photoproduction in collision has long been proposed as an ideal process to probe the existence of odderon. In the current work, we systematically investigate the pho…

We compute the corrections to the exclusive channels () at GeV within the nonrelativistic QCD (NRQCD) factori…
Exclusive radiative production of fully-charmed tetraquarks at Factory
Feng Feng, Yingsheng Huang, Yu Jia +2
We apply the newly developed NRQCD factorization formula to analyze the exclusive production of the fully-charmed tetraquark plus a hard photon at factory. For simplic…
Fragmentation production of fully-charmed tetraquarks at LHC
Feng Feng, Yingsheng Huang, Yu Jia +3
The resonance, very recently discovered in the double- channel at LHCb experiment, has spurred intensive interest in unravelling the nature of the fully charmed tetr…
