Source: Physical Review D. 2015. Vol. 91, № 11. P. 112018-1-112018-9
Type: статьи в журналах
Date: 2015
Description: We present the first upper-limit measurement of the branching fractions of the isospin-violating transitions χc0,2→π0ηc. The measurements are performed using 106×106 ψ(3686) events accumulated with th ... More

Date: 2015
Description: In an analysis of a 2.92  fb−1 data sample taken at 3.773 GeV with the BESIII detector operated at the BEPCII collider, we measure the absolute decay branching fractions B(D0→K−e+νe)=(3.505±0.014±0.03 ... More

Type: статьи в журналах
Date: 2015
Description: Based on data samples collected with the BESIII detector at the BEPCII collider at nine center of mass energies from 4.21 to 4.42 GeV, we search for the production of e+e−→ωχcJ (J=0, 1, 2). The proces ... More

Description: Based on a sample of 2.25×108J/ψ events taken with the BESIII detector at the BEPCII collider, we present the results of a study of the decay J/ψ→ηϕπ+π−. The Y(2175) resonance is observed in the invar ... More

Description: Using a data sample of 106 million ψ(3686) events collected with the BESIII detector operated at the BEPCII storage ring, we study for the first time the decays χcJ→ϕK0SK±π∓ and χcJ→ϕK+K−π0 in the E1 ... More

Type: статьи в журналах
Date: 2014
Description: Using 2.25×108J/ψ events collected with the BESIII detector at the BEPCII storage rings, we observe for the first time the process J/ψ→p¯pa0(980), a0(980)→π0η with a significance of 6.5σ (3.2σ includi ... More
