Study of e^{+}e^{-}→γωJ/ψ and Observation of X(3872)→ωJ/ψ.
We study the e^{+}e^{-}→γωJ/ψ process using 11.6  fb^{-1} e^{+}e^{-} annihilation data taken at center-of-mass energies from sqrt[s]=4.008  GeV to 4.600 GeV with the BESIII detector at the BEPCIIExpand

Abashian-Booth-Crowe effect in basic double-pionic fusion: a new resonance?
We report on an exclusive and kinematically complete high-statistics measurement of the basic double-pionic fusion reaction pn→dπ(0)π(0) over the full energy region of the ABC effect, a pronouncedExpand

Measurement of the π0→e+e-γ Dalitz decay at the Mainz Microtron
The Dalitz decay pi(0) -> e(+) e(-) gamma has been measured in the gamma p -> pi(0) p reaction with the A2 tagged-photon facility at the Mainz Microtron, MAMI. The value obtained for the slopeExpand

Spin Dependence of η Meson Production in Proton-Proton Collisions Close to Threshold.
Taking advantage of the high acceptance and axial symmetry of the WASA-at-COSY detector, and the high polarization degree of the proton beam of COSY, the reaction p[over →]p→ppη has been measuredExpand

Observation of a Resonant Structure in e^{+}e^{-}→K^{+}K^{-}π^{0}π^{0}.
A partial-wave analysis is performed for the process e^{+}e^{-}→K^{+}K^{-}π^{0}π^{0} at the center-of-mass energies ranging from 2.000 to 2.644 GeV. The data samples of e^{+}e^{-} collisions,Expand

First Observation of D^{+}→ημ^{+}ν_{μ} and Measurement of Its Decay Dynamics.
By analyzing a data sample corresponding to an integrated luminosity of 2.93  fb^{-1} collected at a center-of-mass energy of 3.773 GeV with the BESIII detector, we measure for the first time theExpand

Deuteron photodisintegration by polarized photons in the region of the d⁎(2380)
Abstract We report the first large-acceptance measurement of the beam–spin asymmetry for deuteron photodisintegration ( γ → d → p n ) in the photon energy range 420 E γ 620 MeV . The measurementExpand
