Evidence for the decays of Lambda(+)(C) -> Sigma(+) eta and Sigma(+) eta '
(IOP PUBLISHING LTD, 2019)
We study the hadronic decays of Lambda(+)(C) to the final states Sigma(+) eta and Sigma(+) eta', using an e(+) e(-) annihilation data sample of 567 pb(-1) taken at a center-of-mass energy of 4.6 GeV with the BESIII detector ...
Measurement of the phase between strong and electromagnetic amplitudes of J/Psi decays
(Elsevier Science, 2019)
Using 16 energy points of e(+) e(-) annihilation data collected in the vicinity of the J/Psi resonance with the BESIII detector and with a total integrated luminosity of around 100 pb(-1), we study the relative phase between ...
Study of the Dalitz decay J/psi -> e(+)e(-)eta
(Amer Physic Soc., 2019)
We study the electromagnetic Dalitz decay J/psi -> e(+)e(-)eta and search for dielectron decays of a dark gauge boson (gamma') in J/psi -> gamma'eta with the two q decay modes eta -> gamma gamma and eta -> pi(+)pi(-)pi(0) ...
Observation of chi(cJ) -> 4K(S)(0)
(Amer Physic Soc., 2019)
By analyzing (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII collider, the decays of chi(c)(J) -> 4K(S)(0) (J = 0, 1, 2) are observed for the first time with statistical ...
Measurements of the absolute branching fractions and CP asymmetries for D+ -> (KS,LK+)-K-0 (pi(0))
(Amer Physic Soc., 2019)
Using e(+)e(-) collision data corresponding to an integrated luminosity of 2.93 fb(-1) taken at a center-of-mass energy of 3.773 GeV with the BESIII detector, we determine the absolute branching fractions B(D+ -> (KSK+)-K-0) ...
Realization of Dielectric Sheets for Gain Improvement of Ultra-Wideband Horn Antennas Using 3D Printer Technology
(APPLIED COMPUTATIONAL ELECTROMAGNETICS SOC, 2019)
In this work, 3D printing technology had been used to prototyped 10 dielectric sheets with relative dielectric constant of 2.5 for gain improvement of a TEM horn antenna. By loading the 3D printed dielectric sheets to the ...
Partial-wave analysis of J /? ?k+K-?0
(American Physical Society, 2019)
A partial-wave analysis of the decay J/??K+K-?0 has been made using (223.7±1.4)×106 J/? events collected with the BESIII detector in 2009. The analysis, which is performed within the isobar-model approach, reveals contributions ...
A comparative study on the electrical and dielectric properties of Al/Cd-doped ZnO/p-Si structures
(SPRINGER, 2019)
We have reported on the electrical and dielectric properties of Al/CdxZn1-xO/p-Si structures. The cadmium-doped zinc oxide (CdxZn1-xO) thin films with various Cd dopants (x=0.10, 0.20 and 0.30) were deposited on p-Si wafers ...
Search for baryon and lepton number violation in J/psi -> Lambda(+)(c)e(-) + c.c.
(Amer Physic Soc., 2019-04-12)
Using 1.31 x 10(9) J/psi events collected by the BESIII detector at the Beijing Electron Positron Collider, we search for the process J/psi -> Lambda(+)(c)e(-) + c.c. for the first time. In this process, both baryon and ...
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 ...
