Direct renormalization of flavor-changing currents in vNRQCD for decays
Jichen Pan
We present a direct vNRQCD calculation of the two-loop anomalous dimensions of the leading flavor-changing nonrelativistic currents that govern the leptonic decays of the and…
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…
Iterated Agent for Symbolic Regression
Zhuo-Yang Song, Zeyu Cai, Shutao Zhang +8
Symbolic regression (SR), the automated discovery of mathematical expressions from data, is a cornerstone of scientific inquiry. However, it is often hindered by the combinatorial…
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…
Nucleon Energy Correlators for the Color Glass Condensate
Hao-Yu Liu, Xiaohui Liu, Ji-Chen Pan +2
We demonstrate the recently proposed nucleon energy-energy correlator (nucleon EEC) can unveil the gluon saturation in the small- regime in collisions. T…
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…
Complete three-loop QCD corrections to leptonic width of vector quarkonium
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…
Four-lepton decays of neutral vector mesons
Wen Chen, Yu Jia, Zhewen Mo +2
We investigate the rare electromagnetic decays of neutral vector mesons (exemplified by , , , , \ldots) into four charged leptons (, , $2(τ^…
