Precision measurement of the D?0 decay branching fractions
(American Physical Society, 2015)
Using 482 pb-1 of data taken at s=4.009 GeV, we measure the branching fractions of the decays of D?0 into D0?0 and D0? to be B(D?0?D0?0)=(65.5±0.8±0.5)% and B(D?0?D0?)=(34.5±0.8±0.5)%, respectively, by assuming that the ...
Observation of the Decay X (3872) ??0?c1 (1P)
(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 ...
Synthesis of chalcone-imide derivatives and investigation of their anticancer and antimicrobial activities, carbonic anhydrase and acetylcholinesterase enzymes inhibition profiles
(Taylor & Francis, 2018)
The new 1-(4-(3-(aryl)acryloyl)phenyl)-1H-pyrrole-2,5-diones (5a-g) were prepared from 4-aminchalcones (3a-g) and screened for biological activities. All compounds (3a-g and 5a-g), except 3d and 3e displayed good cytotoxic ...

We report the observation and study of the decay J/psi -> phi eta eta' phi eta eta' using 1.3 x 10(9) J/psi events collected with the BESIII detector. Its branching fraction, including all possible intermediate states, is ...
Observation of Z(c)(3900)(0) in e(+)e(-) -> pi(0)pi(0) J/Psi
(American Physical Society, 2015)
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, we observe a new neutral state Zc(39000)0 with a significance of 10.4?. The mass and width are measured to be 3894.8 ± 2.3 ± 3.2 ...
Observation of pseudoscalar and tensor resonances in J/psi -> gamma phi phi

(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 ...
