Meson-meson scattering in two-dimensional QCD
Guo-Ying Chen, Yingsheng Huang, Yu Jia +1
We extend the formalism pioneered by Callan, Coote and Gross to investigate the meson-meson scattering within the framework of 't Hooft model, i.e., the two-dimensional QCD in the…
radiative decay to heavy-light mesons in HQET factorization through
Saadi Ishaq, Yu Jia, Xiaonu Xiong +1
Analogous to NRQCD factorization for heavy quarkonium exclusive production, in this work we propose to employ the heavy-quark-effective-theory (HQET) factorization, which has been…
Optimized predictions for by combining light-cone and NRQCD approaches
Feng Feng, Yu Jia, Wen-Long Sang
The rare process of radiative decay into the meson can serve as an interesting play ground for testing two influential perturbative QCD approaches: non-relativistic quant…
Near-the-origin divergence of Dirac wave functions of hydrogen and operator product expansion
Yingsheng Huang, Yu Jia, Rui Yu
There is a long-standing puzzle concerning the Coulomb solutions of the Dirac equation, i.e., what is the physics governing the weakly divergent near-the-origin behavior of the Dir…
Next-to-next-to-leading-order QCD corrections to at factories
Feng Feng, Yu Jia, Zhewen Mo +2
Within the nonrelativistic QCD (NRQCD) factorization framework, we compute the long-awaited correction for the exclusive double charmonium production process…
