$J / ψ$ Pair Production at the Tevatron with $\sqrt{s}=1.96~\mathrm{TeV}

Cong-Feng Qiao, Li-Ping Sun

We revisit the $J / ψ$ pair production issue at the Fermilab Tevatron Run II with the center-of-mass energy $s = 1.96 TeV$ . Both color-singlet and -octet production mec…

Top Quark Decays into Heavy Quark Mesons

Cong-Feng Qiao, Chong Sheng Li, Kuang-Ta Chao

For top quark decays into heavy quark mesons $Υ$ and $B ˉ_{c}^{*}$ , a complete calculation to the leading order both in QCD coupling constant $α_{s}$ and in $v$ , the typical velocit…

Possible retardation effects of quark confinement on the meson spectrum

Cong-feng Qiao, Han-Wen Huang, Kuang-Ta Chao

The reduced Bethe-Salpeter equation with scalar confinement and vector gluon exchange is applied to quark-antiquark bound states. The so called intrinsic flaw of Salpeter equation…

Electromagnetic Annihilation Rates of $χ_{c 0}$ and $χ_{c 2}$ with Both Relativistic and QCD Radiative Corrections

Han-Wen Huang, Cong-Feng Qiao, Kuang-Ta Chao

We estimate the electromagnetic decay rates of $χ_{c 0} \to γ γ$ and $χ_{c 2} \to γ γ$ by taking into account both relativistic and QCD radiative corrections. The decay ra…
