E. Klempt, A.V. Sarantsev, I. Denisenko, and K.V. Nikonov

TL;DR
This paper reports a search for the tensor glueball in BESIII data, identifying an enhancement in the $ ho o ext{pi}^0 ext{pi}^0$ mass spectrum and discussing its possible relation to high-mass tensor mesons.
Contribution
It presents the first search for the tensor glueball in radiative $J/psi$ decays and identifies a potential signal with a specific pole position.
Findings
Observed an enhancement in the $ ho o ext{pi}^0 ext{pi}^0$ invariant mass distribution.
Identified a pole at approximately 2210 MeV with a width of 360 MeV.
Speculated on the distribution of the tensor glueball among high-mass tensor mesons.
Abstract
The tensor glueball is searched for in BESIII data on radiative decays into and . The invariant mass distribution exhibits an enhancement that can be described by a pole at \,MeV. We speculate if the tensor glueball could be distributed among high-mass tensor mesons.
