Gluon-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 کاملGluon-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 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 کاملMean Field Approximation in Conformation Dynamics
We propose a new approach to the transfer operator based analysis of the conformation dynamics of molecules. It is based on a statistical independence ansatz for the eigenfunctions of the operator related to a partitioning into subsystems. Numerical tests performed on small systems show excellent qualitative agreement between mean field and exact model, at greatly reduced computational cost.
متن کاملMean Field Approximation in Bayesian Variable Selection
Variable selection for a multiple regression model (Noisy Linear Perceptron) is studied with a mean field approximation. In our Bayesian framework, variable selection is formulated as estimation of discrete parameters that indicate a subset of the explanatory variables. Then, a mean field approximation is introduced for the calculation of the posterior averages over the discrete parameters. An ...
