چکیده

In this note we discuss the wave functional approach to the spectrum of pure YangMills theory in 2 + 1 and 3 + 1 dimensions by highlighting the issues of dynamical mass generation and the role played by the kinetic term. We extrapolate our recent analysis of 2+1 Yang-Mills theory to 3+1 dimensions, and under certain heuristic assumptions use a simple quasi-Gaussian vacuum wavefunctional for 3+1 Yang-Mills theory for a preliminary study of the spectrum of glueballs which nicely fits the available lattice simulations. To appear in the proceedings of the first Sowers Theoretical Physics workshop, Virginia Tech, May 2007. [email protected] [email protected] [email protected] [email protected]

Matrix string states in pure

We quantize pure 2d Yang-Mills theory on a torus in the gauge where the field strength is diagonal. Because of the topological obstructions to a global smooth diagonalization, we find string-like states in the spectrum similar to the ones introduced by various authors in Matrix string theory. We write explicitly the partition function, which generalizes the one already known in the literature, ...

Supersymmetric Yang-Mills Theory

We study the spectrum of the softly broken generalized Veneziano-Yankielowicz effective action for N = 1 SUSY Yang-Mills theory. Two dual formulations of the effective action are given. The spurion method is used for the soft SUSY breaking. Masses of the bound states are calculated and mixing patterns are discussed. Mass splittings of pure gluonic states are consistent with predictions of conve...

On the Glueball Spectrum of Pure Yang - Mills Theory in 2 + 1 Dimensions

We present details of the analytic computation of the spectrum of lowest spin glueballs in pure Yang-Mills theory in 2+1 dimensions. The new ingredient is provided by the conjectured new non-trivial expression for the (quasi)Gaussian part of the ground state wave-functional. We show that this wave-functional can be derived by solving the Schrödinger equation under certain assumptions. The mass ...

Modeling The Glueball Spectrum By A Closed Bosonic Membrane

We use an analogy between the Yang-Mills theory Hamiltonian and the matrix model description of the closed bosonic membrane theory to calculate the spectrum of glueballs in the large Nc limit. Some features of the Yang-Mills theory vacuum, such as the screening of the topological charge and vacuum topological susceptibility are discussed. We show that the topological susceptibility has differen...

How to Solve Pure Yang-Mills Theory in 2 + 1 Dimensions

We present details of the recently announced analytic computation of the spectrum of lowest spin glueballs and associated Regge trajectories in the planar limit of pure Yang-Mills theory in 2+1 dimensions. The new ingredient is provided by the computation of a new non-trivial form of the ground state wave-functional. The mass spectrum of the theory is determined by the zeros of Bessel functions...
