Improved measurements of X-cJ -> Sigma(+) (Sigma)over-bar(-) and Sigma(0)(Sigma)over-bar(0) decays
The BESIII collaboration; Kolcu, Onur Buğra (American Physical Society, 2018)Using a data sample of (448.1±2.9)×106 ?(3686) events collected with the BESIII detector at the BEPCII collider, we present measurements of branching fractions for the decays ?cJ??+?- and ?0?0. The decays ?c1,2??+?- and ... -
Observation of e(+)e(-) -> pi(+) pi(-)psi(3770) and D-1(2420)(0)(D)over-bar(0) + c.c
The BESIII collaboration; Kolcu, Onur Buğra (American Physical Society, 2019)Several intermediate states of the reaction channels e+e-??+?-D0D?0 and e+e-??+?-D+D- are studied using the data samples collected with the BESIII detector at center-of-mass energies above 4.08 GeV. For the first time in ... -
Observation of psi(3686) -> p(p)over-bar phi
The BESIII collaboration; Kolcu, Onur Buğra (American Physical Society, 2019)Using a data sample of 4.48×108 ?(3686) events collected with the BESIII detector, we present a first observation of ?(3686)?pp ?, and we measure its branching fraction to be [6.06±0.38(stat)±0.48(syst)]×10-6. In contrast ... -
Observation of the Decay X (3872) ??0?c1 (1P)
The BESIII collaboration; Kolcu, Onur Buğra (American Physical Society, 2019)Using a total of 9.0 fb-1 of e+e- collision data with center-of-mass energies between 4.15 and 4.30 GeV collected by the BESIII detector, we search for the processes e+e-??X(3872) with X(3872)??0?cJ for J=0, 1, 2. We report ... -
Partial-wave analysis of J /? ?k+K-?0
The BESIII collaboration; Kolcu, Onur Buğra (American Physical Society, 2019)A partial-wave analysis of the decay J/??K+K-?0 has been made using (223.7±1.4)×106 J/? events collected with the BESIII detector in 2009. The analysis, which is performed within the isobar-model approach, reveals contributions ... -
Polarization and entanglement in baryon–antibaryon pair production in electron–positron annihilation
The BESIII collaboration; Kolcu, Onur Buğra (Nature Publishing Group, 2019)Particles directly produced at electron–positron colliders, such as the J/? meson, decay with relatively high probability into a baryon–antibaryon pair1. For spin-1/2 baryons, the pair can have the same or opposite helicites. ... -
Precision Study of eta ' -> gamma pi(+) pi(-) Decay Dynamics
The BESIII collaboration; Kolcu, Onur Buğra (American Physical Society, 2018)Using a low background data sample of 9.7×105 J/?????, ?????+?- events, which are 2 orders of magnitude larger than those from the previous experiments, recorded with the BESIII detector at BEPCII, the decay dynamics of ... -
Search for hc ??+?-J /? via ? (3686) ??0?+?-J /?
The BESIII collaboration; Kolcu, Onur Buğra (American Physical Society, 2018)Using a data sample of 448.1×106 ?(3686) events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition hc??+?-J/? via ?(3686)??0hc. No signals of the transition are observed, ... -
Search for rare decay J /? ??e+e-
The BESIII collaboration; Kolcu, Onur Buğra (American Physical Society, 2019)Using a data sample of 448.1×106 ?(3686) events collected at s=3.686 GeV with the BESIII detector at the Beijing Electron-Positron Collider II, we search for the rare decay J/???e+e- via ?(3686)??+?-J/?. No signal events ...
