Observation of a broad 1^-- resonant structure around 1.5 GeV/ in the K^+K^- mass spectrum in J/psi --> K^+K^-pi^0
BES Collaboration, M. Ablikim
A broad peak is observed at low K^+K^- invariant mass in J/psi --> K^+K^-pi^0 decays found in a sample of 5.8\times 10^7 J/psi events collected with the BESII detector. A partial w…
Pseudoscalar production at omega omega threshold in J/psi -> gamma omega omega
Bes Collaboration
The decay channel J/ψ->gamma omega omega, omega -> pi+ pi- pi0 is analyzed using a sample of 5.8x10^7 J/psi events collected with the BESII detector. The omega omega invariant mass…
Photoproduction of Dijets with High Transverse Momenta at HERA
H1 Collaboration
Differential dijet cross sections are measured in photoproduction in the region of photon virtualities Q^2 < 1 GeV^2 with the H1 detector at the HERA ep collider using an integrate…
Observation of a near-threshold enhancement in the ωϕmass spectrum from the doubly OZI suppressed decay J/ψ\to γωϕ
BES Collaboration
An enhancement near threshold is observed in the ωϕinvariant mass spectrum from the doubly OZI suppressed decays of J/ψ\to γωϕ, based on a sample of 5.8 X 10^7 J/ψevents collected…
