Doubly Heavy Baryon Production at γγCollider
S. Y. Li, Z. G. Si, Z. J. Yang
The inclusive production of doubly heavy baryons and at collider is investigated. It is found that the contribution from the heavy quark pair in color t…
Colour Connection and Diquark Fragmentation in e^+e^- \to c \bar c q \bar q \to h's Process
Wei Han, Shi-Yuan Li, Zong-Guo Si +1
The hadronization effects induced by different colour connections of system in annihilation are investigated by a toy model where diquark fragmentation…
Generalized structure of hadron-quark vertex function in Bethe-Salpeter framework: Applications to leptonic decays of V-mesons
Shashank Bhatnagar, Shi-Yuan Li
We employ the framework of Bethe-Salpeter equation under Covariant Instantaneous Ansatz (CIA) to study the leptonic decays of vector mesons. The structure of hadron-quark vertex fu…
Combination of Heavy Quark with Partons from Quark-Gluon Matter: a Scaling Probe
Shi-Yuan Li
In relativistic heavy ion collisions, the cross section of heavy hadron production via the combination of a heavy quark with a light one from the quark-gluon matter can be factoriz…
Study of color connections in annihilation
Feng-lan Shao, Qu-bing Xie, Shi-yuan Li +1
We replace in the event generator JETSET the color singlet chain connection with the color separate state one as the interface between the hard and soft sectors of hadronic process…
