A tale of Bethe logarithms: leptonic widths of and Lamb shift
Yu Jia, Jichen Pan
The rare annihilation decays of -wave spin-triplet quarkonia into lepton pair have to proceed via two-photon intermediate state, which are plagued with the infrared divergence s…
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…
