A conjectured duality between supergravity and N = ∞ gauge theories gives predictions for the glueball masses as eigenvalues for a supergravity wave equations in a black hole geometry, and describes a physics, most close toa hightemeperature expansion of a lattice QCD. We present an analytical solution for eigenvalues and eigenfunctions, with eigenvalues given by zeroes of a certain well-comput...

In this note we adopt the space-time relativistic approach of Feynman’s propagators (for bosons and fermions) instead of the canonical LagrangianHamiltonian quantized field theory. Indeed the former alternative is preferred to the latter for the developments of our basic ideas that exhibit the connection between the propagator of quantum mechanics and Lévy’s stochasticity. More precisely the re...

A suggestive phenomenological relation is found among the lepton and quark masses which suggests a new insight into the problem of generations and also gives a prediction for the top quark mass in agreement with the range of values which is actually expected.

We discuss fitting hadronic Green functions versus time t to extract mass values in quenched lattice QCD. These data are themselves strongly correlated in t. With only a limited number of data samples, the method of minimising correlated χ 2 is unreliable. We explore several methods of modelling the correlations among the data set by a few parameters which then give a stable and sensible fit ev...

The mass spectrum of sulfur (S,) obtained with the ion trap mass spectrometer is compared with that obtained using an E-B spectrometer. Each ion in the spectrum is examined for fragmentation and the vapor shown to consist mostly of the SB oligomer. The chemical ionization spectra using methane, isobutane, ammonia, and water are also examined and an estimate made of the proton affinity of Ss. Us...

We derive the BPS mass formulae of the Dirichlet branes from the Born-Infeld type action. BPS saturation is realized when the brane has the minimal volume while keeping the appropriate winding numbers. We apply the idea to two cases, type IIA superstring compactified on T 4 and K3. The result is consistent with the string duality, and the expected spectrum for the BPS states is reproduced.

We analyze the implications of a Higgs discovery on possible " new–physics " scenarios, for m H up to ∼ 700 GeV. For this purpose we critically review lower and upper limits on the Higgs mass in the SM and in the MSSM, respectively. Furthermore, we discuss the general features of possible " heavy " (m H > ∼ 2m Z) Higgs scenarios by means of a simple heavy–fermion condensate model.

Results are reported for N* masses in the 1/2+ and 1/2− sectors on an anisotropic lattice. The gauge action is the usual plaquette plus rectangle type, the quark action is of the D234 type, both having tadpole-improved tree-level coefficients. Clear splittings from the nucleon ground state are observed with smeared operators and 500 configurations. The first excited states in each channel are f...
