Improved measurements of χcJ → Σ+ Σ - and Σ0 Σ 0 decays IMPROVED MEASUREMENTS of ... M. ABLIKIM et al.
(American Physical Society, 2018)
Using a data sample of (448.1±2.9)×106 ψ(3686) events collected with the BESIII detector at the BEPCII collider, we present measurements of branching fractions for the decays χcJ→Σ+Σ- and Σ0Σ0. The decays χc1,2→Σ+Σ- and ...
Observation of a Neutral Charmoniumlike State Zc (4025)0 in e+e- → (D∗ D ¯ ∗)0π0
(American Physical Society, 2015)
We report a study of the process e+e-→(D∗D¯∗)0π0 using e+e- collision data samples with integrated luminosities of 1092 pb-1 at s=4.23 GeV and 826 pb-1 at s=4.26 GeV collected with the BESIII detector at the BEPCII storage ...
Measurement of the B0 lifetime and flavor-oscillation frequency using hadronic decays reconstructed in 2019-2021 Belle II data
(American Physical Society, 2023)
We measure the B0 lifetime and flavor-oscillation frequency using B0→D(∗)-π+ decays collected by the Belle II experiment in asymmetric-energy e+e- collisions produced by the SuperKEKB collider operating at the ϒ(4S) ...
Observation of ψ(3770) → ηJ/ψ
(American Physical Society, 2023)
Using a data sample collected with the BESIII detector operating at the BEPCII storage ring, the Born cross section of the process e+e- -> eta J=psi at a center-of-mass energy pffisffi = 3.773 GeV is measured to be (8.88 ...
First Observation of the Direct Production of the chi(c1) in e(+)e(-) Annihilation
(AMER PHYSICAL SOC, 2022)
We study the direct production of the J(PC) = 1(++) charmonium state chi(c1)(1P) in electron-positron annihilation by carrying out an energy scan around the mass of the chi(c1)(1P). The data were collected with the BESIII ...
Study of the h(c)(1(1)P(1)) meson via psi(2S) -> pi(0)h(c) decays at BESIII
(AMER PHYSICAL SOC, 2022)
Using 448 million psi(2S) events, the spin-singlet P-wave charmonium state h(c)(1(1)P(1)) is studied via the psi(2S) -> pi(0)h(c) decay followed by the h(c) -> gamma eta(c) transition. The branching fractions are measured ...
Measurement of e+e- → ωπ+π- cross section at <mml:msqrt>s</mml:msqrt>=2.000 to 3.080 GeV
(Springer Science and Business Media Deutschland GmbH, 2023)
A partial wave analysis on the process e+e− → ωπ+π− is performed using 647 pb−1 of data sample collected by using the BESIII detector operating at the BEPCII storage ring at center-of-mass (c.m.) energies from 2.000 GeV ...
