GKZ-hypergeometric systems for Feynman integrals
Tai-Fu Feng, Chao-Hsi Chang, Jian-Bin Chen +1
Basing on the systems of linear partial differential equations derived from Mellin-Barnes representations and Miller's transformation, we obtain GKZ-hypergeometric systems of one-l…
Next-to-leading order QCD corrections to the production of and through -boson decays
Xu-Chang Zheng, Chao-Hsi Chang, Xing-Gang Wu +2
In this paper, we calculate the total decay widths for the -boson decays, and , up to next-to-leading order (NLO) accuracy…
The NLO fragmentation functions of heavy quarks into heavy quarkonia
Xu-Chang Zheng, Chao-Hsi Chang, Xing-Gang Wu
In the paper, we derive the next-to-leading order (NLO) fragmentation function for a heavy quark, either charm or bottom, into a heavy quarkonium or . The ultra-violet div…
The mass spectra and wave functions for the doubly heavy baryons with heavy diquark core
Qiang Li, Chao-Hsi Chang, Si-Xue Qin +1
The mass spectra and wave functions for the doubly heavy baryons are computed under the picture that the two heavy quarks inside a doubly heavy baryon, such as two -quarks in $Ξ…
The QCD NLO fragmentation functions for or quark to or meson and their application
Xu-Chang Zheng, Chao-Hsi Chang, Tai-Fu Feng +1
The fragmentation functions for or quark to or meson are derived up to QCD next-to-leading order (NLO). They are further computed numerically and presen…
