Amplitude of process via one loop in unitary gauge (I. Details of calculation with Dyson scheme)
Shi-Yuan Li
Decay amplitude of process via one loop in the unitary gauge is presented. The divergent integrals including those of high divergence orders typical of unitary gaug…
Triply heavy tetraquark states in a mass-splitting model
Shi-Yuan Li, Yan-Rui Liu, Zi-Long Man +3
In a modified chromomagnetic interaction model, assuming to be the lowest tetraquark and treating it as the reference state, we systematically…
Doubly heavy tetraquark states in a mass splitting model
Shi-Yuan Li, Yan-Rui Liu, Zi-Long Man +2
Treating the as a compact state and using its mass as a reference scale, we systematically estimate the masses of doubly heavy tetraqua…
Pseudoscalar heavy quarkonium production in heavy ion ultraperipheral collision
Jun Jiang, Shi-Yuan Li, Xiao Liang +4
The inclusive production of pseudoscalar heavy quarkoniua ( and ) via photon-photon fusion in heavy ion ultraperipheral collision (UPC) are calculated to QCD next-…
, , and other compact states
Shi-Yuan Li, Yan-Rui Liu, Zi-Long Man +2
We study the spectrum and rearrangement decays of S-wave tetraquark states in a simplified quark model. The masses and widths are estimated by assuming that the…
Mass suppression effect in QCD radiation and hadron angular distribution in jet
Chuan-Hui Jiang, Hai Tao Li, Shi-Yuan Li +1
The finite mass of the heavy quark suppresses the collimated radiations, which is generally referred to as the dead cone effect. In this paper, we study the distribution of hadron…
