Analysis of D+ -> (K)over-bar(0)e(+)nu(e) and D+ -> pi(0)e(+)nu(e) semileptonic decays
(Amer Physical Soc., 2017)
Using 2.93 fb(-1) of data taken at 3.773 GeV with the BESIII detector operated at the BEPCII collider, we study the semileptonic decays D+ -> (K) over bar (0)e(+)nu(e) and D+ -> pi(0)e(+)nu(e). We measure the absolute decay ...
Study of J/psi and psi(3686) -> Sigma(1385)(0)(Sigma)over-bar(1385)(0) and Xi(0)(Xi)over-bar(0)
(Elsevier Science, 2017)
We study the decays of J/psi and psi(3686) to the final states Sigma(1385)(0)(Sigma) over bar (1385)(0) and Xi(0)(Xi) over bar (0) based on a single baryon tag method using data samples of (1310.6 +/- 7.0) x 10(6) J/psi ...
Determination of the number of J/psi events with inclusive J/psi decays
(Chinese Physical, 2017)
A measurement of the number of J/psi events collected with the BESIII detector in 2009 and 2012 is performed using inclusive decays of the J/psi. The number of J/psi events taken in 2009 is recalculated to be (223.7 +/- ...
Measurement of branching fractions for psi(3686) -> gamma eta ', gamma eta, and gamma pi(0)
(Amer Physical Soc., 2017)
Using a data sample of 448 x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII storage ring, the decays psi(3686) -> gamma eta and psi(3686) -> gamma pi(0) are observed with a statistical ...
Measurements of the center-of-mass energies at BESIII via the di-muon process
(2016)
From 2011 to 2014, the BESIII experiment collected about 5 fb$^{-1}$ data at center-of-mass energies around 4 GeV for the studies of the charmonium-like and higher excited charmonium states. By analyzing the di-muon process ...
Evidence for e(+)e(-) -> gamma eta(c)(1S) at center-of-mass energies between 4.01 and 4.60 GeV
(Amer Physical Soc., 2017)
We present first evidence for the process e(+)e(-) -> gamma eta(c)(1S) at six center-of-mass energies between 4.01 and 4.60 GeV using data collected by the BESIII experiment operating at BEPCII. We measure the Born cross ...
Branching fraction measurement of J=Psi -> KSKL and search for J=Psi -> KSKS
(Amer Physical Soc., 2017)
Using a sample of 1.31 x 10(9) J/Psi events collected with the BESIII detector at the BEPCII collider, we study the decays of J/Psi -> KSKL and KSKS. The branching fraction of J/Psi -> KSKL is determined to be B(J/Psi -> ...
Searching for beauty-fully bound tetraquarks using lattice nonrelativistic QCD
(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 - › ? 0? 0hc and a neutral charmoniumlike structure Zc(4020)0
(2014)
Using data collected with the BESIII detector operating at the Beijing Electron Positron Collider at center-of-mass energies of s?=4.23, 4.26, and 4.36 GeV, we observe e+e-›?0?0hc for the first time. The Born cross sections ...
