Model-independent determination of the relative strong-phase difference between D-0 and (D)over-bar(0) -> K-S,L(0)pi(+)pi(-) and its impact on the measurement of the CKM angle gamma/phi(3)
(Amer Physical Soc., 2020)
Crucial inputs for a variety of CP-violation studies can be determined through the analysis of pairs of quantum-entangled neutral D mesons, which are produced in the decay of the psi(3770) resonance. The relative strong-phase ...
Search for the Decay D-s(+) -> a(0)(980)(0)e(+)nu(e)
(Amer Physical Soc., 2021)
Using 6.32 fb(-1) of electron-positron collision data recorded by the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV, we present the first search for the decay D-s(+) -> a(0)(980)(0)e(+)nu(e), ...
Measurement of the absolute branching fraction of the inclusive decay Lambda c+-> KS0X: (BESIII Collaboration)
(Springer, 2020)
We report the first measurement of the absolute branching fraction of the inclusive decay Lambda c+-> KS0X. The analysis is performed using an e+e- collision data sample corresponding to an integrated luminosity of 567 ...
Study of the process e(+) e(-) -> pi(0)pi(0)J/psi and neutral charmoniumlike state Z(c)(3900)(0)
(Amer Physical Soc., 2020)
Cross sections of the process e(+)e(-) -> pi(0)pi(0)J/psi at center-of-mass energies between 3.808 and 4.600 GeV are measured with high precision by using 12.4 fb(-1) of data samples collected with the BESIII detector ...
First observations of h(c )-> hadrons
(Amer Physic Soc., 2019-04-24)
Based on (4.48 +/- 0.03) x 10(8) Psi(3686) events, collected with the BESIII detector at the BEPCII storage ring, five h(c) hadronic decays are searched for via the process Psi(3686) -> pi(0)h(c). Three of them, h(c) -> p ...
Observation of D-0 -> K-1 (1270) (-)e(+)nu(e)
(Amer Physical Soc., 2021)
Using 2.93 fb(-1) of e(+)e(-) collision data taken with the BESIII detector at a center-of-mass energy of 3.773 GeV, the observation of the D-0 -> K-1 (1270)(-)e(+)nu(e) semileptonic decay is presented. The statistical ...
Search for the decay D-s(+) -> gamma e (+) nu(e)
(Amer Physical Soc., 2019-04-09)
A search for the rare radiative leptonic decay D-s(+) -> gamma e(+)nu(e) is performed for the first time using electron-positron collision data corresponding to an integrated luminosity of 3.19 fb(-1), collected with the ...
Structural, Optical, Electrical and Electrocatalytic Activity Properties Of Luminescent Organic Carbon Quantum Dots
(Wiley, 2018-05-08)
Carbon is an essential element in human life and recently becoming technologically prominent due to the emerging field of "Carbononics". We demonstrate organic carbon quantum dots (qdots) containing nitrile bonded (C N ...
Search for the Lepton Number Violating Decay Sigma(-) -> pe(-) e(-) and the Rare Inclusive Decay Sigma(-) -> Sigma(+) X
(Amer Physical Soc., 2021)
Using a data sample of (1310.6 +/- 7.0) x 10(6) J/psi events taken with the BESIII detector at the center-of-mass energy of 3.097 GeV, we search for the first time for the lepton number violating decay Sigma(-) -> pe(-) ...

(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 ...
