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...
متن کاملABJM Dibaryon Spectroscopy
We extend the proposal for a detailed map between wrapped D-branes in Anti-de Sitter space and baryon-like operators in the associated dual conformal field theory provided in hep-th/0202150 to the recently formulated AdS4 × CP/ABJM correspondence. In this example, the role of the dibaryon operator of the 3dimensional CFT is played by a D4-brane wrapping a CP ⊂ CP. This topologically stable D-br...
متن کاملTaking dibaryon fields seriously
We propose a low energy effective field theory of QCD at the scale of pion mass for the NB = 2 sector, NB being the baryon number, which contains two dibaryon fields in addition to the nucleons and pions. It has a well defined counting, is renormalizable and the nucleon-nucleon scattering amplitudes are manifestly unitary at leading order. We work out a lower energy effective theory for nucleon...
متن کاملH-Dibaryon Results from KTeV
Results from the KTeV experiment at Fermilab using Ξ hyperons are presented, especially the first form-factor (FF) measurement from its semi-leptonic decay. This decay, which is an important test of the Standard Model, was observed for the first time using the 1997 KTeV experiment. We also report on the analysis of a large samples of Ξ weak radiative decays, and a search for the decay of a ligh...
متن کاملMass of the H dibaryon.
Recent lattice QCD calculations have reported evidence for the existence of a bound state with strangeness -2 and baryon number 2 at quark masses somewhat higher than the physical values. By developing a description of the dependence of this binding energy on the up, down and strange quark masses that allows a controlled chiral extrapolation, we explore the hypothesis that this state is to be i...
