Observation of e(+)e(-) -> phi chi(c1) and phi chi(c2) at root s=4.600 GeV
(Amer Physical Soc., 2018)
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring at a center-of-mass energy of root s = 4.600 GeV, we search for the production of e(+)e(-) -> phi chi(c0,1,2). A search is also ...
Determination of the number of psi(3686) events at BESIII
(Science Press, 2018)
The numbers of psi(3686) events accumulated by the BESIII detector for the data taken during 2009 and 2012 are determined to be (107.0 +/- 0.8)x10(6) and (341.1 +/- 2.1)x10(6), respectively, by counting inclusive hadronic ...
A training model for “typesetting operator” profession in the publishing industry (design-implementation-evaluation)
(Elsevier, 2013)
Nowadays the main problem that faced by people is adapted to rapidly the conditions of life by the effect of technology. The field that that technological alteration is felt mostly is undoubtedly the experience of individual ...
2D Coverage Analysis of Sensor Networks with Random Node Deployment
(IEEE, 2017)
In last few decades, as a result of the advances in microelectromechanical systems, Wireless Sensor Networks (WSNs) have gained a considerable attention due to their low-cost, low-power and small-scale sensor nodes which ...
Observation of e(+)e(-) -> eta h(c) at center-of-mass energies from 4.085 to 4.600 GeV
(Amer Physical Soc., 2017)
We observe for the first time the process e(+) e(-) -> eta h(c) with data collected by the BESIII experiment. Significant signals are observed at the center-of-mass energy root s = 4.226 GeV, and the Born cross section is ...
Observation of the dalitz decay ?’??e+e?
(American Physical Society, 2015)
We report the first observation of the Dalitz decay ?’??e+e?, based on a data sample of 1.31 billion J/? events collected with the BESIII detector. The ?’ mesons are produced via the J/????’ decay process. The ratio ...
Measurements of ? (3686) ?k- ? ? ¯ ++ c. c. and ? (3686) ??K- ? ? ¯ ++ c. c.
(American Physical Society, 2015)
Using a sample of 1.06×108?(3686) events produced in e+e- collisions at s=3.686 GeV and collected with the BESIII detector at the BEPCII collider, we present studies of the decays ?(3686)?K-??¯++c.c. and ?(3686)??K-??¯++c.c.. ...
Observation of the isospin-violating decay J /? ???0f0 (980)
(American Physical Society, 2015)
Using a sample of 1.31×109 J/? events collected with the BESIII detector at the BEPCII collider, the decays J/????+?-?0 and J/????0?0?0 are investigated. The isospin-violating decay J/????0f0(980) with f0(980)??? is observed ...
Luminosity measurements for the R scan experiment at BESIII
(Chinese Physical, 2017)
By analyzing the large-angle Bhabha scattering events e(+)e(-) -> (gamma)e(+)e(-) and diphoton events e(+)e(-) -> (gamma)gamma gamma for the data sets collected at center-of-mass (c.m.) energies between 2.2324 and 4.5900 ...
OPCOMITS: Developing an Adaptive and Intelligent Web Based Educational System Based on Concept Map Model
(Wiley, 2016)
Concept map model is a method that creates domain model by identifying the relationship between concepts in course contents. This study presents an adaptive intelligent web based learning system called OPCOMITS (Object ...
