Study of the process e(+)e(-) -> phi eta at center-of-mass energies between 2.00 and 3.08 GeV
(2021)
The process e(+)e(-) -> phi eta is studied at 22 center-of-mass energy points (root s) between 2.00 and 3.08 GeV using 715 pb(-1) of data collected with the BESIII detector. The measured Born cross section of e(+)e(-) -> ...
Measurement of the Cross Section for e+e- →Hadrons at Energies from 2.2324 to 3.6710 GeV
(American Physical Society, 2022)
Based on electron-positron collision data collected with the BESIII detector operating at the Beijing Electron-Positron Collider II storage rings, the value of Rσ(e+e-→hadrons)/σ(e+e-→μ+μ-) is measured at 14 center-of-mass ...
Search for baryon- and lepton-number violating decays D0 → p ¯ e+ and D0 →pe-
(American Physical Society, 2022)
Using an electron-positron collision data sample corresponding to an integrated luminosity of 2.93 fb-1 collected with the BESIII detector at a center-of-mass energy of 3.773 GeV, we search for the baryon-number and ...
Study of the decay Ds+ → KS0 KS0 π+ and observation of an isovector partner to f0 (1710)
(American Physical Society, 2022)
Using e+e-annihilation data corresponding to a total integrated luminosity of 6.32 fb-1 collected at center-of-mass energies between 4.178 and 4.226 GeV with the BESIII detector, we perform an amplitude analysis of the ...
Measurement of the inclusive branching fraction for psi (3686) -> K-S(0) + anything
(ELSEVIER, 2021)
Using 5.9 pb(-1) of e(+)e(-) annihilation data collected at center-of-mass energies from 3.640 to 3.701 GeV with the BESIII detector at the BEPCII Collider, we measure the observed cross sections of e(+)e(-) -> (KSX)-X-0 ...
Measurement of the branching fraction of the doubly cabibbo-suppressed decay D0 →k+π-π0 and search for D0 →k+π-π0π0
(American Physical Society, 2022)
Using 2.93 fb-1 of e+e- collision data collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we present a measurement of the branching fraction of the doubly Cabibbo-suppressed (DCS) decay D0→K+π-π0 ...
Probing CP symmetry and weak phases with entangled double-strange baryons
(NATURE RESEARCH, 2022)
Though immensely successful, the standard model of particle physics does not offer any explanation as to why our Universe contains so much more matter than antimatter. A key to a dynamically generated matter-antimatter ...
Search for new hadronic decays of h(c) and observation of h(c) -> p(p)over-bar eta
(SPRINGER, 2022)
A search for the hadronic decays of the h(c) meson to the final states p (p) over bar pi(+)pi(-)pi(0), p (p) over bar eta and p (p) over bar pi(0) via the process psi(3686) -> pi(0)(h)c is performed using (4.48 +/- 0.03) ...
Partial wave analysis of J/ψ →γη η
(American Physical Society, 2022)
Using a sample of (10.09±0.04)×109 J/ψ events collected with the BESIII detector, a partial wave analysis of J/ψ→γη η is performed. The masses and widths of the observed resonances and their branching fractions are reported. ...
Search for the decay D0 →π0ν ν ¯
(American Physical Society, 2022)
We present the first experimental search for the rare charm decay D0→π0νν¯. It is based on an e+e- collision sample consisting of 10.6×106 pairs of D0D¯0 mesons collected by the BESIII detector at s=3.773 GeV, corresponding ...
