Gluon-Meson Duality
The QCD-vacuum is characterized by the Higgs phenomenon for colored scalar fields. In this dual picture the gluons appear as the octet of vector mesons. Also quarks and baryons are identified. Gluonmeson and quark-baryon duality can account in a simple way for realistic masses of all low-mass hadrons and for their interactions. e-mail: [email protected] Universality is a cent...
متن کاملGluon-Meson Duality in the Mean Field Approximation
In a gauge-fixed language gluon-meson duality can be described as the Higgs mechanism for “spontaneous symmetry breaking” of color. We present a mean field computation which suggests that this phenomenon is plausible in QCD. One obtains realistic masses of the light mesons and baryons. e-mail: [email protected] A dual description of QCD in the low momentum or strong coupling ...
متن کاملDuality in Meson Electroproduction
We propose to study quark-hadron duality in meson electroproduction. While duality between inclusive electron-hadron scattering in the resonance and deep inelastic regimes (Bloom-Gilman or quark-baryon duality) is well established, the existence of a similar duality in meson electroproduction has not yet been tested. In the inclusive case, duality implies that single-quark scattering governs th...
متن کاملDuality in Meson Electroproduction – Update
Experiment E00-108, Duality in Meson Electroproduction, was approved by PAC-18 for 20 days. It was scheduled for 10 PAC-days of data taking in August 2003. The experiment explored the duality between quark and hadron descriptions in semi-inclusive electron scattering. In particular, E00-108 studied the meson (pion, and, with reduced statistics, kaon) electroproduction cross-section as a functio...
متن کاملOn planar gluon amplitudes/Wilson loops duality
There is growing evidence that on-shell gluon scattering amplitudes in planar N = 4 SYM theory are equivalent to Wilson loops evaluated over contours consisting of straight, light-like segments defined by the momenta of the external gluons. This equivalence was first suggested at strong coupling using the AdS/CFT correspondence and has since been verified at weak coupling to one loop in perturb...
