dc.description.abstractBased on a data sample of (2712.4 +/- 14.3) x 106(3686) events collected with the BESIII detector at the BEPCII collider, the M1 transition psi(3686) - c(2S) with c(2S) - K over bar K is studied, where K over bar K is K+K-0 or K0SK +/--/+. The mass and width of the c(2S) are measured to be (3637.8 +/- 0.8(stat) +/- 0.2(syst)) MeV=c2 and (10.5 +/- 1.7(stat) +/- 3.5(syst)) MeV, respectively. The product branching fraction B((3686) - c(2S)) x B(c(2S) - K over bar K) is determined to be (0.97 +/- 0.06(stat) +/- 0.09(syst)) x 10-5. Using B(c(2S) - K over bar K) = (1.86+0.68 -0.49)%, we obtain the branching fraction of the radiative transition to be B((3686) - c(2S)) = (5.2 +/- 0.3(stat) +/- 0.5(syst)+1.9 -1.4 (extr)) x 10-4, where the third uncertainty is due to the quoted B(c(2S) - K over bar K).en_US
