J/psi radiative decays and the glueball candidates


  • Mr. Arkaitz RODAS

Primary authors



We present recent work on the determination of several scalar and tensor resonances produced in $J/\psi$ radiative decays. We extract 7 total inelastic resonances, of which the most interesting ones are the $f_0(1500)$ and $f_0(1710)$, considered glueball candidates. We implement many different parameterizations fulfilling the unitarity and analyticity requirements to asses our uncertainties. Finally the radiative couplings of the $f_0(1500)$ and $f_0(1710)$ resonances are compared.
