Evaluation of Self-Intersecting Wilson Loop in the Stochastic Vacuum Model
Dmitri Antonov
A Wilson loop is evaluated within the stochastic vacuum model for the case when the respective contour is self-intersecting and its size does not exceed the correlation length of t…
The O-Na and Mg-Al Anticorrelations in Turn-Off and early Subgiants in Globular Clusters
R. G. Gratton, P. Bonifacio, A. Bragaglia +16
High dispersion spectra (R>40,000) for a quite large number of stars at the main sequence turn-off and at the base of the subgiant branch in NGC6397 and NGC6752 were obtained with…
Renormalization Group and Dynamics of Supersymmetric Gauge Theories
K. Konishi
We discuss questions related to renormalization group and to nonperturbative aspects of non-Abelian gauge theories with N=2 and/or N=1 supersymmetry. Results on perturbative and no…
One Body Density Matrix, Natural Orbits and Quasi Hole States in 16O and 40Ca
A. Fabrocini, G. Co'
The one body density matrix, momentum distribution, natural orbits and quasi hole states of 16O and 40Ca are analyzed in the framework of the correlated basis function theory using…
Topics in Non-Perturbative QCD
Adriano Di Giacomo
General aspects of non-perturbative field theory are discussed.The definition of condensates is analysed.Mechanisms of color confinement are rewieved.
Phase Shifts and Mixing Parameters for Elastic Proton-Deuteron Scattering
A. Kievsky, J. L. Friar, G. L. Payne +2
The eigenphase shifts and mixing parameters for elastic p-d scattering below the deuteron-breakup threshold are calculated for the AV14 two-body potential using two different numer…
Evolution equations for the effective four-quark interactions in QCD
Enrico Meggiolaro, Christof Wetterich
A nonperturbative renormalization group equation describes how the momentum dependent four-quark vertex depends on an infrared cutoff. We find a quasilocal one-particle irreducible…
Evidence for Three Nucleon Force Effects in p-d Elastic Scattering
A. Kievsky, M. H. Wood, C. R. Brune +6
A new measurement of the p-d differential cross section at Ep= 1 MeV has been performed. These new data and older data sets at energies below the deuteron breakup are compared to c…
The critical equation of state of the 2D Ising model
M. Caselle, M. Hasenbusch, A. Pelissetto +1
We compute the 2n-point coupling constants in the high-temperature phase of the 2d Ising model by using transfer-matrix techniques. This provides the first few terms of the expansi…
Confining strings in the Abelian-projected SU(3)-gluodynamics II. 4D-case with -term
Dmitri Antonov
The generalization of 4D confining string theory to the SU(3)-inspired case is derived. It describes string representation of the Wilson loop in the SU(3)-analogue of compact QED e…
Critical Phenomena and Renormalization-Group Theory
Andrea Pelissetto, Ettore Vicari
We review results concerning the critical behavior of spin systems at equilibrium. We consider the Ising and the general O()-symmetric universality classes, including the $N\to…
Proton-deuteron elastic scattering at low energies
C. R. Brune, W. H. Geist, H. J. Karwowski +6
We present measurements of differential cross sections and the analyzing powers A_y, iT11, T20, T21, and T22 at E_c.m.=431.3 keV. In addition, an excitation function of iT11(theta_…
Observation of an Excess in the Search for the Standard Model Higgs Boson at ALEPH
ALEPH Collaboration
A search has been performed for the Standard Model Higgs boson in the data sample collected with the ALEPH detector at LEP, at centre-of-mass energies up to 209GeV. An excess of 3s…
Hamiltonian structure and quantization of 2+1 dimensional gravity coupled to particles
Luigi Cantini, Pietro Menotti, Domenico Seminara
It is shown that the reduced particle dynamics of 2+1 dimensional gravity in the maximally slicing gauge has hamiltonian form. This is proved directly for the two body problem and…
Monopoles, vortices and confinement in SU(3) gauge theory
L. Del Debbio, A. Di Giacomo, B. Lucini
We compute, in SU(3) pure gauge theory, the vacuum expectation value (vev) of the operator which creates a vortex wrapping the lattice through periodic boundary conditions (d…
Quantum delocalization of the electric charge
Detlev Buchholz, Sergio Doplicher, Giovanni Morchio +2
The classical Maxwell-Dirac and Maxwell-Klein-Gordon theories admit solutions of the field equations where the corresponding electric current vanishes in the causal complement of s…
The Gibbs ensemble of a vortex filament
F. Flandoli, M. Gubinelli
We introduce a statistical ensemble for a single vortex filament of a three dimensional incompressible fluid. The core of the vortex is modelled by a quite generic stochastic proce…
Non standard analysis of the solar neutrino anomaly (updated including the SNO day/night spectral data)
Riccardo Barbieri, Alessandro Strumia
Continuing previous work, a model independent analysis of the solar neutrino anomaly is performed in terms of neutrino oscillations, allowing a comparison with the predictions of t…
A Possible Universal Treatment of the Field Strength Correlator in the Abelian-Projected SU(2)-Theory
Dmitri Antonov
An integral relation between two functions parametrizing the bilocal field strength correlator within the Stochastic Vacuum Model is obtained in the effective Abelian-projected SU(…

Ph. de Forcrand, M. D'Elia, M. Pepe
We study the potential between a static center monopole and antimonopole in 4d SU(2) Yang-Mills theory. Using a new numerical method, we show that the 't Hooft loop is a dual order…
