Observation of the decay Lambda(+)(c) -> Sigma(-)pi(+)pi(+)pi(0)
(Elsevier Science, 2017)
We report the first observation of the decay Lambda(+)(c) -> Sigma(-)pi(+)pi(+)pi(0), based on data obtained in e(+)e(-) annihilations with an integrated luminosity of 567 pb(-1) at vs = 4.6 GeV. The data were collected ...
Observation of psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi
(Amer Physic Soc., 2017)
Using 4.479 x 10(8) psi(3686) events collected with the BESIII detector, we search for the decays psi(3686) -> e(+)e(-)chi(cJ) and chi(cJ) -> e(+)e(-)J/psi, where J = 0, 1, 2. The decays psi(3686) -> e(+)e(-)chi(cJ) and ...
Dark photon search in the mass range between 1.5 and 3.4 GeV/c
(Elsevier Science, 2017)
Using a data set of 2.93 fb taken at a center-of-mass energy root s = 3.773 GeV with the BESIII detector at the BEPCII collider, we perform a search for an extra U(1) gauge boson, also denoted as a dark photon. We examine ...
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 ...
An assessment of health information systems through the perspective of computer engineering students and medical students
(Avicena Publishing, 2019)
Introduction: Computer Engineering Students (CES) and Medical Students (MS) will actively participate in the management of health information system in the future. Aim: The aim of the study was to evaluate the views of CES ...
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 ...
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 ...
