Combining Monte Carlo and variational techniques, we compute the mass gap (or glueball mass) in the SC/(Z) lattice gauge theory. We obtain the estimate mR = (2.4 i 0.6) fl, K being the string tension. We also discuss previous results derived by numerical or strong coupling methods and present Monte Carlo data on the second moment of the correlation length.

With the use of asymptotic completeness, the full Green’s function of an N-body system is expanded in configuration space by the solutions of distorted fields which consist of multi-squarewell potentials, All wave functions involved in the expansion have analytical form. thus making the calculation practicable. In addition to the 2-body channel, distorted fields for 3- and 4-body intermediate channels are introduced. The action of these fields is controlled by specified projectors according to different asymptotic status. Different kinds of intermediate channels are included in the zero-order term of the expansion so as to improve the convergence.

We propose a fully conformal invariant theory describing gravity as a spontaneously broken theory. Newton’s constant is automatically generated. We find through the study of classical solutions of the equations of motion that the breakdown of conformal symmetry can take place at the tree approximation without introducing arbitrary forms for the scalar potential. Using cosmological metrics, which we find natural from the physical point of view, some conclusions can be drawn regarding the nature of those metrics. The case of constant scalar curvature is particularly interesting, and gives rise to a gravitational version of the Goldstone theorem.
Hydrodvnamical Theory for Equilibrium Time Correlation Functions of Hard Rods. HERBERT SPOHN. Institut des Hautes Etudes Scientitiques, 35, route de Chartres. 91440 Bures-sur-Yvette, France. It is pointed out that a gas of hard rods in one dimension serves as a non-degenerate hydrodynamical theory of time correlation functions. The current-current correlation Integrated over space, are 6(t) times the matrix of transport coefftcients.
