Unitary Symmetry and Leptonic Decays
An analysis of leptonic decays based on unitary symmetry for strong interactions (eightfold way) and the V-A theory for weak interactions is presented. An explanation for the observed predominance ofExpand

Exponential hadronic spectrum and quark liberation
Abstract The exponentially increasing spectrum proposed by Hagedorn is not necessarily connected with a limiting temperature, but it is present in any system which undergoes a second order phaseExpand

Glueball masses and string tension in lattice QCD
We study glueball masses in lattice QCD. We present the first numerical determination of the mass of the lowest spin 2 state in the scaling region, and find that it is close to the lowest spin 0Expand

Leptonic Decay of Heavy Flavors: A Theoretical Update
Abstract The spectrum of charged leptons in semileptonic B and D decays is reanalyzed. Special emphasis is given to the behaviour near the end point which is of importance for the determination ofExpand

▪ Abstract We review the status of hyperon semileptonic decays. The central issue is the Vus element of the CKM matrix, for which we obtain Vus = 0.2250 (27). This value is similar in precision toExpand

New high statistics measurement of Ke4 decay form factors and ππ scattering phase shifts
We report results from a new measurement of the Ke4 decay K±→π+π-e±ν by the NA48/2 collaboration at the CERN SPS, based on a partial sample of more than 670 000 Ke4 decays in both charged modesExpand

In this paper we describe an implementation of the Lattice Boltzmann Equation method for fluid-dynamics simulations on the APE100 parallel computer. We have performed a simulation of aExpand

Bounds on the Fermions and Higgs Boson Masses in Grand Unified Theories
Abstract In the framework of grand unifying theories, the requirement that no interaction becomes strong and no vacuum instability develops up to the unification energy is shown to imply upper boundsExpand
