Dynamical Symmetry and the Thermofield State at Large N
نویسندگان
چکیده
We discuss thermofield double QFT at real time, in the large N limit. First, we establish a (dynamical) symmetry, which argue holds general for real-time portion of Schwinger–Kelydish contour. At N, this symmetry is seen to generate one-parameter degeneracy stationary collective solutions. The construction explicitly worked out on an example O(N) vector QFT. As nontrivial application, describe corresponding (large N) state formalism.

A Dynamical Origin of Little Higgs -hidden Local Symmetry in Large N F Qcd - *
In this write-up I summarize the main points of our recent work, in which we showed that the large flavor QCD is regarded as a dynamical origin of little Higgs, and that the mass of such a little Higgs becomes actually very small.
متن کاملDynamical Aspects of Large N Reduced Models
We study the large N reduced model of D-dimensional Yang-Mills theory with special attention to dynamical aspects related to the eigenvalues of the N×N matrices, which correspond to the space-time coordinates in the IIB matrix model. We first put an upper bound on the extent of space time by perturbative arguments. We perform a Monte Carlo simulation and show that the upper bound is actually sa...
متن کاملSIGNATURES of DYNAMICAL SYMMETRY BREAKING at TEVATRON UPGRADE and LHC
We present some results on the usefulness of upgraded Tevatron and LHC hadron colliders to test the idea of a strongly interacting sector as responsible for the electroweak symmetry breaking. The calculations are performed within an effective lagrangian description, called the BESS model 1 (BESS standing for Breaking Electroweak Symmetry Strongly), which provides for a rather general frame base...
متن کاملDynamical Symmetry Breaking with Large Anomalous Dimension in Gauge Theories
An analysis is given of the dynamical symmetry breaking of semi-simple gauge groups. We construct a class of renormalizable gauge theories for the dynamically broken topcolor and technicolor interactions. It is shown that a fourFermi interaction in the strong coupling phase emerges by the tumbling of semi-simple gauge groups in the low energy region. In our models the topcolor interaction provi...
متن کاملNoether Symmetry in f(T) Theory at the anisotropic universe
As it is well known, symmetry plays a crucial role in the theoretical physics. On other hand, the Noether symmetry is a useful procedure to select models motivated at a fundamental level, and to discover the exact solution to the given lagrangian. In this work, Noether symmetry in f(T) theory on a spatially homogeneous and anisotropic Bianchi type I universe is considered. We discuss the Lagran...
