Dynamical Mass Generation in Quantum Field Theory : Some Methods with Application to the Gross-neveu Model and Yang-mills Theory
نویسندگان
چکیده
We introduce some techniques to investigate dynamical mass generation. The Gross-Neveu model [1] (GN) is used as a toy model, because the GN mass gap is exactly known [2], making it possible to check reliability of the various methods. Very accurate results are obtained. Also application to SU(N) Yang-Mills (YM) is discussed.

Lee-Yang edge singularity in the three-dimensional Gross-Neveu model at finite temperature
We discuss the relevance of the Lee-Yang edge singularity to the finite-temperature Z2-symmetry restoration transition of the Gross-Neveu model in three dimensions. We present an explicit result for its large-N free-energy density in terms of ζ(3) and the absolute maximum of Clausen’s function. The Gross-Neveu model in d = 3 dimensions provides a remarkable example of a second order temperature...

LTH–601 We discuss the 2P P I expansion, a summation of the bubble graphs up to all orders, by means of the 2D Gross-Neveu toy model, whose exact mass gap and vacuum energy are known. Then we use the expansion to give analytical evidence that a dimension two gluon condensate exists for pure Yang-Mills in the Landau gauge. This A a µ A a µ condensate consequently gives rise to a dynamical gluon ...

Dynamical mass generation by source inversion: Calculating the mass gap of the Gross-Neveu model. Abstract We probe the Gross-Neveu model with a source-term JΨΨ. We find an expression for the renormalization scheme and scale invariant source J, as a function of the generated mass gap. The expansion of this function is organized in such a way that all scheme and scale dependence is reduced to on...
متن کاملHeaviside transform of the effective potential in the Gross-Neveu model
A fresh study on the perturbative expansion is presented with the help of Heaviside transform with respect to the mass. We apply Heaviside transform to the effective potential in the Gross-Neveu model and carry out perturbative approximation of the massless potential by dealing with the resulting Heaviside function. We find that accurate values of the dynamical mass can be obtained from the Hea...
متن کاملVariational solution of the Gross - Neveu model I . The large - N limit
In this first paper we begin the application of variational methods to renor-malizable asymptotically free field theories, using the Gross-Neveu model as a laboratory. This variational method has been shown to lead to a numerically convergent sequence of approximations for the anharmonic oscillator. Here we perform a sample calculation in lowest orders, which show the superficially disastrous s...
