Heavy quarkonium decay $V \to g g g$ with both relativistic and QCD radiative corrections

Hong-Mei Jiang, Chao-Jie Fan, Jun-Kang He +1

In the heavy quarkonium decay process $V \to g g g$ ( $V = J / I ¨ , I^¥$ ), making a definite prediction including relativistic corrections has so far remained a significant challenge. In…

Study of $I^ p$ and $I^ˉ p$ scatterings via quasipotential Bethe-Salpeter equation

Yaning Chen, Jun He

Motivated by recent BESIII measurements of the $I^ p \to I^ p$ and $I^ˉ p \to I^ˉ p$ scattering processes, we investigate these reactions within the framework of the quasipoten…

Revisiting the line shape of $e^+e^-\to \jpsi Î·$ cross section

Chang-Man Gan, Jun-Kang He, Wen-Long Sang +1

We calculate the cross sections for the processes $e^+e^-\to \jpsi Î·$ and $e^+e^-\to \jpsi Î·^\prime$ at various CM energies $s$ . We first predict these cross sections by c…
