Recent study about XYZ particles at BESIII (12'+3')

Jul 29, 2021, 11:15 AM


Parallel session talk QCD and Hadronic Physics T06: QCD and Hadronic Physics


Johannes Bloms


In this talk recent XYZ results at BESIII will be reviewed, that includes: Observation of a near-threshold enhancement in the Lambda Lambda-bar mass spectrum from e+ e- -> phi Lambda Lambda-bar at the center-of-mass energies from 3.51 to 4.60 GeV; Observation of e+ e- -> eta psi(2S) at the center-of-mass energies from 4.236 to 4.600 GeV; Cross section measurement of e+ e- -> p pbar eta and e+ e- -> p pbar omega at center-of-mass energies between 3.773 GeV and 4.6 GeV; Search for reaction e+ e- -> chi_cJ pi+ pi- and a charmonium-like structure decaying to chi_cJ pi+/- between 4.18 and 4.60 GeV; Search for the reaction channel e+ e- -> eta_c eta pi+ pi- at center-of-mass energies from 4.23 to 4.60 GeV.
