Hadronic Production of Meson Induced by the Heavy Quarks inside the Collision Hadrons
Chao-Hsi Chang, Cong-Feng Qiao, Jian-Xiong Wang +1
In general-mass variable-flavor-number (GM-VFN) scheme, the `heavy quark mechanisms' of meson hadroproduction via the sub-processes and $g+\bar…
Pion Electromagnetic Form Factor in the Factorization Formulae
Xing-Gang Wu, Tao Huang
Based on the light-cone (LC) framework and the factorization formalism, the transverse momentum effects and the different helicity components' contributions to the pion form…
B-Meson Wavefunction with Contributions from 3-particle Fock States
Tao Huang, Cong-Feng Qiao, Xing-Gang Wu
The B-meson light-cone wavefunctions, , are investigated up to the next-to-leading order in Fock state expansion in the heavy quark limit. In order to know the tran…
BCVEGPY2.0: A upgrade version of the generator BCVEGPY with an addendum about hadroproduction of the -wave states
Chao-Hsi Chang, Jian-Xiong Wang, Xing-Gang Wu
The generator BCVEGPY is upgraded by adding the hadroproduction of the -wave excited states (denoted by or by and ) and by improving some…
The Color-Octet Contributions to -wave Meson Hadroproduction
Chao-Hsi Chang, Cong-Feng Qiao, Jian-Xiong Wang +1
The contributions from the color-octet components and to the or (the -wave meso…
B-Meson Wavefunction in the Wandzura-Wilczek Approximation
Tao Huang, Xing-Gang Wu, Ming-Zhen Zhou
The B-meson wavefunction has been studied with the help of the vacuum-to-meson matrix element of the nonlocal operators in the heavy quark effective theory. In order to obtain the…
