Measurements of absolute branching fractions for D mesons decays into two pseudoscalar mesons
(Amer Physical Soc., 2018)
Using a data sample of e(+)e(-) collision data with an integrated luminosity of 2.93 fb(-1) taken at the center-of-mass energy root s = 3.773 GeV with the BESIII detector operating at the BEPCII storage rings, we measure ...
Measurement of e(+)e(-) -> K(K)over-barJ/psi cross sections at center-of-mass energies from 4.189 to 4.600 GeV
(Amer Physical Soc., 2018)
We investigate the process e(+)e(-) -> K (K) over barJ/psi at center-of-mass energies from 4.189 to 4.600 GeV using 4.7 fb(-1) of data collected by the BESIII detector at the BEPCII collider. The Born cross sections for ...
Search for invisible decays of omega and phi with J/psi data at BESIII
(Amer Physical Soc., 2018)
Using a data sample of (1310.6 +/- 7.0) x 10(6) J/psi events collected with the BESIII detector operating at the BEPCII collider, we perform the first experimental search for invisible decays of a light vector meson (V = ...
Measurement of e(+)e(-) -> D(D)over-bar cross sections at the psi(3770) resonance
(Iop Publishing, 2018)
We report new measurements of the cross sections for the production of D (D) over bar final states at the psi(3770) resonance. Our data sample consists of an integrated luminosity of 2.93 fb(-1) of e(+)e(-) annihilation ...

(Amer Physical Soc., 2018)
By analyzing an e(+)e(-) data sample corresponding to an integrated luminosity of 2.93 fb(-1) taken at a centerof- mass energy of 3.773 GeV with the BESIII detector, we measure the branching fractions of the Cabibbofavored ...
Measurement of the integrated Luminosities of cross-section scan data samples around the psi(3770) mass region
(Iop Publishing, 2018)
To investigate the nature of the psi(3770) resonance and to measure the cross section for e(+)e(-) -> D (D) over bar, a cross-section scan data sample, distributed among 41 center-of-mass energy points from 3.73 to 3.89 ...
