Search for the y (4140) via e+e- →γφJ /ψ at s =4.23, 4.26 and 4.36 GeV
© 2015 American Physical Society.Using data samples collected at center-of-mass energies 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 φJ/ψ. No significant signal is observed and upper limits on σ[e+e-→γY(4140)]·B(Y(4140)→φJ/ψ) at the 90% confidence level are estimated as 0.35, 0.28, and 0.33 pb at s=4.23, 4.26, and 4.36 GeV, respectively.
