Observation of the Semileptonic Decay D-0 -> a(0)(980)(-)e(+)nu(e) and Evidence for D+ -> a(0)(980)(0)e(+)nu(e)
(Amer Physical Soc., 2018)
Using an e(+)e(-) collision data sample of 2.93 fb(-1) collected at a center-of-mass energy of 3.773 GeV by the BESIII detector at BEPCII, we report the observation of D-0 -> a(0)(980)(-)e(+)nu(e) and evidence for D+ -> ...
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 ...
History and evaluation of mobile wimax
(Mili Publications, 2012)
The growing demand for mobile Internet and wireless multimedia applications has motivated the development of broadband wireless access technologies in recent years. Mobile WiMAX was the first mobile broadband wireless ...
Measurement of the Dynamics of the Decays D-s(+ )-> eta(('))e(+)nu(e)
(Amer Physic Soc., 2019)
Using e(+)e(-) annihilation data corresponding to an integrated luminosity of 3.19 fb(-1) collected at a center-of-mass energy of 4.178 GeV with the BESIII detector, we measure the absolute branching fractions BDs+->eta ...
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 ...
Observation of psi(3686) -> p(p)over-bar phi
(American Physical Society, 2019)
Using a data sample of 4.48×108 ?(3686) events collected with the BESIII detector, we present a first observation of ?(3686)?pp ?, and we measure its branching fraction to be [6.06±0.38(stat)±0.48(syst)]×10-6. In contrast ...
Modeling of gravity anomalies due to 2D geological structures using Genetic algorithm
(Istanbul University, 2015)
In this paper, a new modeling technique is introduced using Genetic Algorithm (GA). In this method, Genetic algorithm (GA) is modified and used as an optimization method in geophysics applications. The problem at hand is ...
Polarization and entanglement in baryon–antibaryon pair production in electron–positron annihilation
(Nature Publishing Group, 2019)
Particles directly produced at electron–positron colliders, such as the J/? meson, decay with relatively high probability into a baryon–antibaryon pair1. For spin-1/2 baryons, the pair can have the same or opposite helicites. ...
Observation of OZI-suppressed decays chi(cJ) -> omega phi
(Amer Physic Soc., 2019)
Decays chi(cJ)(J = 0, 1, 2) -> omega phi are studied using (448.1 +/- 2.9) x 10(6)psi(3686) events collected with the BESIII detector in 2009 and 2012. In addition to the previously established chi(c0) -> omega phi, the ...
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 = ...
