Observation of D+ -> f(0) (500)e(+) nu(e) and Improved Measurements of D -> rho e(+) nu(e)
(Amer Physic Soc., 2019)
Using a data sample corresponding to an integrated luminosity of 2.93 fb(-1) recorded by the BESIII detector at a center-of-mass energy of 3.773 GeV, we present an analysis of the decays D-0 -> pi(-) pi(0) e(vertical bar) ...
Measurements of e(+)e(-)-> (KSK +/-)-K-0 pi(-/+)pi(0)and (KSK +/-)-K-0 pi(-/+)eta at center-of-mass energies from 3.90 to 4.60 GeV
(Amer Physical Soc., 2019)
Using 5.2 fb(-1) e(+)e(-) annihilation data samples collected with the BESIII detector, we measure the cross sections of e(+)e(-)->(KSK +/-)-K-0 pi(-/+)pi(0) and (KSK +/-)-K-0 pi(-/+)eta at center-of-mass energies from ...
Observation of the Singly Cabibbo-Suppressed Decay D + › ? ? + and Evidence for D 0 › ? ? 0
(APS Physics, 2016)
Based on 2.93 fb-1 e +e - collision data taken at center-of-mass energy of 3.773 GeV by the BESIII detector, we report searches for the singly Cabibbo-suppressed decays D + › ??+ and D 0 › ??0 . A double tag technique is ...
Study of two-photon decays of pseudoscalar mesons via J=? radiative decays
(Amer Physical Soc., 2018)
Using a sample of 4.48 x 10(8) Psi(3686) events collected with the BESIII detector at the BEPCII collider, we study the two-photon decays of the pseudoscalar mesons pi(0,) eta , eta' , eta(1405), eta(1475), eta(1760), and ...
Search for h(c) -> pi(+)pi(-) J/psi via psi(3686) -> pi(0)pi(+)pi(-) J/psi
(Amer Physical Soc., 2018)
Using a data sample of 448.1 x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII, we perform search for the hadronic transition h(c)-> pi(+)pi(-) J/psi via psi (3686) -> pi(0)hc. No signals ...
Measurement of e(+) e(-) -> K+ K- cross section at root s=2.00-3.08 GeV
(Amer Physical Soc., 04.02.2019)
The cross section of the process e(+) e(-) -> K+ K- is measured at a number of center-of-mass energies root s from 2.00 to 3.08 GeV with the BESIII detector at the Beijing Electron Positron Collider (BEPCII). The results ...
