Recent dibaryon studies at ANKE

Kaon pair production in proton-proton collisions at COSY-ANKE

The near-threshold production of kaon-pairs has been investigated in protonproton collisions at Cooler Synchrotron (COSY)at Forschungszentrum Jülich. In the pp → ppKK reaction, the invariant mass distributions of Kp, Kpp, and KK indicate the presence of both Kp and KK final state interactions. Total cross sections for pp → ppφ reaction have been determined at excess energies ε of 18.5, 34.5, an...

Recent studies of Charmonium Decays at CLEO

Decays of a bound state of a quark and its antiquark, quarkonium, provide an excellent laboratory for studying QCD. Particularly, heavy quarkonia such as charmonium states are less relativistic, thus play a special role in probing strong interactions. CLEO recently has accumulated data taken at the ψ(2S) resonance, providing a total of 27M ψ(2S) decays. With the combination of this large statis...

Recent Qcd Studies at the Tevatron

Since the beginning of Run II at the Fermilab Tevatron, the QCD physics groups of the CDF and DØ experiments have worked to reach unprecedented levels of precision for many QCD observables. Thanks to the large dataset over 3 fb of integrated luminosity recorded by each experiment many important new measurements have recently been made public and will be summarized in this paper.

Dibaryon Spectroscopy

The AdS/CFT correspondence relates dibaryons in superconformal gauge theories to holomorphic curves in Kähler-Einstein surfaces. The degree of the holomorphic curves is proportional to the gauge theory conformal dimension of the dibaryons. Moreover, the number of holomorphic curves should match, in an appropriately defined sense, the number of dibaryons. Using AdS/CFT backgrounds built from the...
