Mini-workshop on glueball hunting

1 Jun 2021, 14:00 → 2 Jun 2021, 17:30 Europe/Berlin

Online

Davide Vadacchino (Trinity College Dublin), Francesco Giacomo Knechtli (Bergische Universitaet Wuppertal (DE)), Francesco Knechtli (Unknown), Mike Peardon

The mini-workshop on glueball hunting will be held online on the afternoons of the 1st and 2nd of June, 2021.  The aim of the workshop is to bring together people investigating the properties of glueballs from different angles. Topics to be addressed are the experimental efforts to identify glueballs at colliders, the current status of lattice searches and the use modern analytical tools.  The workshop is organized as to facilitate the participation of people from different time zones.  The talks will span 40 minutes, followed by 15 minutes discussion sessions.

15:05 → 15:45 Scalar Mesons and the Fragmented Glueball

Evidence for the scalar glueball is reported. The evidence stems from an analysis of BESIII data on radiative J/ψ data into π0π0, KSKS, ηη, and φω. The coupled-channel analysis is constrained by a large number of further data. The data are described by ten scalar isoscalar mesons, covering the range from f0(500) to f0(2330). Five resonances are interpreted as mainly-singlet states in SU(3), five as mainly-octet states. The mainly-singlet resonances are produced over the full mass range, the production of octet state is limited to the 1500 to 2100 MeV mass range. The peak is interpreted as scalar glueball. Its mass, width and yield are determined to M(glueball)= (1865±25) MeV, Γ(glueball)= (370±50+30−20) MeV, Y(J/ψ→γG0)=(5.8±1.0)·10^(−31)
