Quenched Supersymmetry
We study the effects of quenching in Super-Yang-Mills theory. While supersymmetry is broken, the lagrangian acquires a new flavour U(1 | 1) symmetry. The anomaly structure thus differs from the unquenched case. We derive the corresponding low-energy effective lagrangian. As a consequence, we predict the mass splitting expected in numerical simulations for particles belonging to the lowest-lying...
متن کاملquenched approximation
Previous work at 6=g 2 = 5:7 with quenched staggered quarks is extended with new calculations at 5.85 and 6.15 on lattices up to 32 3 64. These calculations allow a more detailed study of extrapolation in quark mass, nite volume and lattice spacing than has heretofore been possible. We discuss how closely the quenched spectrum approaches that of the real world.
متن کاملQuenched Random Graphs
Spin models on quenched random graphs are related to many important optimization problems. We give a new derivation of their mean-field equations that elucidates the role of the natural order parameter in these models. CPTH-A264.1093 April 1994 † Laboratoire Propre du Centre National de la Recherche Scientifique UPR A.0014 Spin models on quenched random graphs have been studied extensively in r...
متن کاملThe Quenched Continuum Limit
Our increasing ability to carry out unquenched simulations means that the quenched approximation is no longer required. There is an outstanding issue associated with the quenched continuum limit, however, which we address here. At the same time we point out the ingredients that are necessary to obtain an accurate result in the continuum limit, since these ingredients will also be important for ...
متن کاملQuenched chiral logarithms.
I develop a diagrammatic method for calculating chiral logarithms in the quenched approximation. While not rigorous, the method is based on physically reasonable assumptions, which can be tested by numerical simulations. The main results are that, at leading order in the chiral expansion, (a) there are no chiral logarithms in quenched fπ, for mu = md; (b) the chiral logarithms in BK and related...
