Observation and study of the decay J/psi -> phi eta eta '
(Amer Physical Soc., 2019)
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 ...
Performance evaluation of logistics enterprise based on the fuzzy analytic hierarchy process
(IEOM Society, 2018)
Today, there is increasing competition in all markets. Companies must evaluate performance in order to be able to survive in this competitive environment and to be able to see the extent to which they achieve the targets ...
An Investigation of Transition Flow in Porous Media by Event Driven Molecular Dynamics Simulation
(Isfahan Univ Technology, 2021)
Aim of this study is to investigate the properties of mono-atomic gas flow through the porous medium by using Event-Driven Molecular Dynamics (EDMD) simulation in the transition regime. The molecules and the solid particles ...
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, 2016)
Based on a sample of (1310.6±10.5)×106 J/? events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay J/????? is performed in order to study the intermediate states. ...
Distributed Storage Capacity Modelling of EV Parking Lots
(IEEE, 2015)
As the power grids have been evolved to be more smarter, distributed energy resources (DER) and Electric vehicles (EVs) provide a new and effective storage capacity during peak loading times. EVs are the new and upcoming ...
Observation of the W-annihilation decay D-s(+) -> omega pi(+) and evidence for D-s(+) -> omega K+
(Amer Physic Soc., 2019-05-13)
We report the observation of W-annihilation decay D-s(+) -> omega pi(+) and evidence for D-s(+) -> omega K+ in a data sample corresponding to an integrated luminosity of 3.19 fb(-1) collected with the BESIII detector at a ...
Precision Study of eta ' -> gamma pi(+) pi(-) Decay Dynamics
(American Physical Society, 2018)
Using a low background data sample of 9.7×105 J/?????, ?????+?- events, which are 2 orders of magnitude larger than those from the previous experiments, recorded with the BESIII detector at BEPCII, the decay dynamics of ...
Search for the weak decays J/? ? D(?)- s e+?e + c.c
(American Physical Society, 2014)
Using a sample of 2.25 × 108 J/? events collected with the BESIII detector at the BEPCII collider, we search for the J/? semileptonic weak decay J/? ? D-s e+?e+ c.c. with a much higher sensitivity than previous searches. ...
Observation of e(+)e(-) -> pi(+) pi(-)psi(3770) and D-1(2420)(0)(D)over-bar(0) + c.c
(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 ...
