Baryon Mass and Phase Transitions in Large N Gauge Theory
نویسنده
چکیده
We calculate baryon mass inN = 4 largeN gauge theory by means of AdS/CFT correspondence, and find that phase transitions occur when temperature or theta angle takes a critical value. Furthermore, we find there are bound states of Wbosons in Higgs phase.

We study the phase structure of two dimensional pure lattice gauge theory with a Chern term. The symmetry groups are non-Abelian, finite and disconnected sub-groups of SU(3). Since the action is imaginary it introduces a rich phase structure compared to the originally trivial two dimensional pure gauge theory. The Z3 group is the center of these groups and the result shows that if we use one ...
متن کاملReal–time dynamics of a hot Yang-Mills theory: a numerical analysis
High temperature baryon number non conservation in the electroweak theory caused by the anomaly of the baryonic current is important for the understanding of the origin of baryonic matter in the universe. After the work of Ref. [1] it was realized that the baryon number nonconservation, caused by thermal field fluctuations between gauge-equivalent vacua with different winding numbers could be l...
متن کاملA survey of large N continuum phase transitions
The main focus of this talk is the physics of large N QCD on a continuum torus. A cascade of phase transitions associated with the breaking of U(1) symmetries will be discussed. The continuum Wilson loop as a function of its area will be discussed along with its universality properties and the associated double scaling limit. Some recent progress in twisted Eguchi-Kawai is presented. Gauge fiel...

متن کاملEffective Lagrangians for Qcd: Deconfinement and Chiral Symmetry Restoration
Effective Lagrangians for Quantum Chromodynamics (QCD) especially suited for understanding deconfinement and chiral symmetry restoration at non-zero temperature and matter density are reviewed. These effective theories allow one to study generic properties of phase transitions using non-order parameter fields without loosing the information encoded in the true order parameter. For the pure gaug...
