Type: Parallel Session: Hadron decays, production and interactions-4
Track: Hadron Decays, Production and Interactions
The production of charmonium(-like) states in pp collisions probes both perturbative and non-perturbative regimes of QCD. It is important to improve our understanding of the strong interaction. The LHCb experiment has been making important contributions to such studies, owing to the large yields provided by the LHC and the unique coverage of the forward rapidity region. This talk presents the late ... More

1. We present a new study of the exclusive production of $f_{1}(1285)$ at energies relevant for the HADES ($pp$) and PANDA ($p\bar{p}$) experiments at FAIR. The $VV$-fusion ($V=\rho,\omega$) processes and the $\gamma p\to f_{1}p$ reaction are discussed [arXiv:2105.07192]. 2. Diffractive production of $f_{1}$ within the tensor-pomeron approach is also discussed. Comparisons with the WA102 data and ... More

Type: Parallel Session: Hadron decays, production and interactions-4
Track: Hadron Decays, Production and Interactions
Up to now, the production of resonances in electron-positron annihilation has only been observed for states with quantum numbers JPC = 1−−. The direct production of the 1++ states could happen through two-photon or neutral current. Due to the smallness of the production rate, this process has never been observed experimentally. With the high luminosity and good performance of the BESIII exper ... More

Track: Hadron Decays, Production and Interactions
The following topics will be reported: Measurement of the branching fractions of psi(3686) -> Sigma0bar Lambda + c.c. and chi_cJ (J=0,1,2) -> Lambda Lambda-bar; Search for new hadronic decays of hc and observation of hc -> K+ K- pi+ pi- pi0; Observation of the decays chi_cJ -> Sigma0 anti-p K+ + c.c. (J=0,1,2); Inclusive chi_cJ and J/psi decay distributions.
