Measurement of A baryon polarization in e(+) e(-) -> Lambda(Lambda)over-bar at root s=3.773 GeV
(AMER PHYSICAL SOC, 2022)
Using a data sample of psi(3770) events collected with the BESIII detector at BEPCII corresponding to an integrated luminosity of 2.9 fb-1, we report a measurement of A spin polarization in e+ e- -> Lambda(Lambda) over bar ...
Search for a CP-odd light Higgs boson in J/psi -> gamma A(0)
(AMER PHYSICAL SOC, 2022)
Using J/psi radiative decays from 9.0 billion J/psi events collected by the BESIII detector, we search for di-muon decays of a CP-odd light Higgs boson (A(0)), predicted by many new physics models beyond the Standard Model, ...
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 ...
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 h(c) -> pi(0) J/psi
(SPRINGER, 2022)
A search for the decay h(c) -> pi(0) J/psi is performed using a sample of h(c) produced in the reaction e(+)e(-) -> pi(+)pi(-)h(c). The data samples were collected with the BESIII detector at center-of-mass energies between ...
