Search for C-parity violation in J/? › ?? and ??
(2014)
Using 1.06×108 ?(3686) events recorded in e+e- collisions at s?=3.686??GeV with the BESIII at the BEPCII collider, we present searches for C-parity violation in J/?›?? and ?? decays via ?(3686)›J/??+?-. No significant ...
Study of eta(1475) and X(1835) in radiative J/psi decays to gamma phi
(Amer Physical Soc., 2018)
The decay J/psi -> gamma gamma phi is studied using a sample of 1.31 x 10(9) J/psi events collected with the BESIII detector. Two structures around 1475 MeV/c(2) and 1835 MeV/c(2) are observed in the gamma phi invariant ...
Observation of the Singly Cabibbo-Suppressed Decay D + › ? ? + and Evidence for D 0 › ? ? 0
(APS Physics, 2016)
Based on 2.93 fb-1 e +e - collision data taken at center-of-mass energy of 3.773 GeV by the BESIII detector, we report searches for the singly Cabibbo-suppressed decays D + › ??+ and D 0 › ??0 . A double tag technique is ...
Study of J/Psi -> p(p)over-bar phi at BESIII
(2016)
Using a data sample of 1.31×109 J/? events accumulated with the BESIII detector, the decay J/?›pp¯? is studied via two decay modes, ?›KS0KL0 and ?›K+K-. The branching fraction of J/?›pp¯? is measured to be B(J/?›pp¯?)=[5 ...
Search for h(c) -> pi(+)pi(-) J/psi via psi(3686) -> pi(0)pi(+)pi(-) J/psi
(Amer Physical Soc., 2018)
Using a data sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition h(c)-> pi(+)pi(-) J/psi via psi (3686) -> pi(0)hc. No signals ...
Measurement of the branching fraction for ?(3770) › ??c0
(Elsevier, 2016)
By analyzing a data set of 2.92fb-1 of e+e- collision data taken at s=3.773GeV and 106.41×106 ?(3686) decays taken at s=3.686GeV with the BESIII detector at the BEPCII collider, we measure the branching fraction and the ...
Search for the weak decay ?'›K±?± and precise measurement of the branching fraction B(J/?›??')
(2016)
We present the first search for the rare decay of ?' into K±?± in J/?›??', using a sample of 1.3×109 J/? events collected with the BESIII detector. No significant signal is observed, and the upper limit at the 90\% confidence ...
Precise Measurement of the e+e- ??+?-J /? Cross Section at Center-of-Mass Energies from 3.77 to 4.60 GeV
(American Physical Society, 2017)
The cross section for the process e+e-??+?-J/? is measured precisely at center-of-mass energies from 3.77 to 4.60 GeV using 9 fb-1 of data collected with the BESIII detector operating at the BEPCII storage ring. Two resonant ...
