چکیده
Based on 106×10(6)ψ(3686) events collected with the BESIII detector at the BEPCII facility, a partial wave analysis of ψ(3686)→ppπ0 is performed. The branching fraction of this channel has been determined to be B(ψ(3686)→ppπ0)=(1.65±0.03±0.15)×10(-4). In this decay, 7 N* intermediate resonances are observed. Among these, two new resonances, N(2300) and N(2570) are significant, one 1/2+ resonance with a mass of 2300(-30-0)(+40+109) MeV/c2 and width of 340(-30-58)(+30+110) MeV/c2, and one 5/2- resonance with a mass of 2570(-10-10)(+19+34) MeV/c2 and width of 250(-24-21)(+14+69) MeV/c2. For the remaining 5 N* intermediate resonances [N(1440), N(1520), N(1535), N(1650) and N(1720)], the analysis yields mass and width values that are consistent with those from established resonances.

Resonances from J / Ψ and Ψ ′ Decays
The Institute of High Energy Physics at Beijing runs an electron-positron collider (BEPC) with a general purpose solenoidal detector, the Beijing Spectrometer (BES)[1], which is designed to study exclusive final states in ee annihilations at the center of mass energy from 3000 to 5600 MeV. In this energy range, the largest cross sections are at the J/Ψ(3097) and Ψ(3686) resonant peaks. At prese...

In inclusive decays of the Ψ (3097), electromagnetic and gluonic annihilation amplitudes add incoherently, namely they are 90 out of phase. We argue that this incoherence must persist in each exclusive decay channel. For inclusive Ψ (3686) decays, we suggest the absence of a significant direct annihilation amplitude into three gluons and propose a new amplitude via QCD anomalies and the hc (352...
متن کاملS-D mixing and ψ(3770) production in e+e− annihilation and B decay and its radiative transitions
The large decay rate observed by Belle for B+ → ψ(3770)K+, which is comparable to B+ → ψ(3686)K+, might indicate either an unexpectedly large S-D mixing angle |θ| ≈ 40o or the leading role of the color-octet mechanism in D-wave charmonium production in B decay. By calculating the production rate of ψ(3770) in the continuum e+e− annihilation at √ s = 10.6 GeV with these two possible approaches (...
متن کاملNew Results From CLEO and BES
Latest experimental results from BES in the charmonium mass region, and those from CLEO in the bottomonium and charmonium spectroscopy are reviewed. 1. Preamble I am going to talk about new results from CLEO and BES, two detectors half a world apart, trying to catch the same particles. CLEO used to do physics in the b-quark region ( √ s = 9 − 11 GeV). It has many credits in bottomonium (bb̄) spe...

We suggest the ratio of the ψ′′(3770)/ψ′(3686) production cross sections as an unambiguous probe of the dominance of hard, pointlike physics in charmonium production. If hard physics dominates the charmonium production the ratio : σ(ψ ) σ(ψ) ≈ Γ(ψ→ll) Γ(ψ′→l+l−) ≈ 0.1 is independent of the process. We argue that since the dominant DD̄ decay mode of the ψ′′-meson can be detected with a high effic...
