Using data samples collected at center-of-mass energies sqrt(s)=4.23, 4.26, and 4.36 GeV with the BESIII detector operating at the BEPCII storage ring, we search for the production of the charmoniumlike state Y(4140) through a radiative transition followed by its decay to phi J/Psi. No significant signal is observed and upper limits on sigma[e+e- -->Y(4140)] x B(Y(4140)-->phi J/Psi) at the 90% confidence level are estimated as 0.35, 0.28, and 0.33 pb at sqrt(s)=4.23, 4.26, and 4.36 GeV, respectively.

Abstract
Using data samples collected at center-of-mass energies sqrt(s)=4.23, 4.26, and 4.36 GeV with the BESIII detector operating at the BEPCII storage ring, we search for the production of the charmoniumlike state Y(4140) through a radiative transition followed by its decay to phi J/Psi. No significant signal is observed and upper limits on sigma[e+e- -->Y(4140)] x B(Y(4140)-->phi J/Psi) at the 90% confidence level are estimated as 0.35, 0.28, and 0.33 pb at sqrt(s)=4.23, 4.26, and 4.36 GeV, respectively.File in questo prodotto:
