Ground state of N=Z doubly closed shell nuclei in CBF theory
A. Fabrocini, F. Arias de Saavedra, G. Co' +1
The ground state properties of N=Z doubly closed shell nuclei are studied within correlated basis function theory. A truncated version of the Urbana v14 realistic potential, with s…
Critical Dynamics of the Hybrid Monte Carlo Algorithm
SESAM, TXL collaboration, : +13
We investigate the critical dynamics of the Hybrid Monte Carlo algorithm approaching the chiral limit of standard Wilson fermions. Our observations are based on time series of leng…

The ground state of medium-heavy nuclei with non central forces
A. Fabrocini
We study microscopically the ground state properties of 16O and 40Ca nuclei within correlated basis function theory. A truncated version of the realistic Urbana v14 (U14) potential…
Measurement of the B0 B0-bar oscillation frequency using pi-B meson charge-flavor correlations in p p-bar collisions at sqrt{s} = 1.8 TeV
CDF Collaboration, F. Abe et. al
We present a measurement of the B0 B0-bar oscillation frequency using a flavor tagging method based on correlations of B meson flavor with the charge of other particles produced in…
Anisotropic String Cosmology at Large Curvatures
Stefano Foffa, Michele Maggiore
We study the effect of the antisymmetric tensor field on the large curvature phase of string cosmology. It is well-known that a non-vanishing value of leads to an a…
Monte Carlo results for three-dimensional self-avoiding walks
Sergio Caracciolo, Maria Serena Causo, Andrea Pelissetto
We discuss possible sources of systematic errors in the computation of critical exponents by renormalization-group methods, extrapolations from exact enumerations and Monte Carlo s…
Initial Results from the CHOOZ Long Baseline Reactor Neutrino Oscillation Experiment
The CHOOZ collaboration
Initial results are presented from CHOOZ, a long-baseline reactor-neutrino vacuum-oscillation experiment. Electron antineutrinos were detected by a liquid scintillation calorimeter…
A critical comparison of different definitions of topological charge on the lattice
B. Alles, M. D'Elia, A. Di Giacomo +1
A detailed comparison is made between the field-theoretic and geometric definitions of topological charge density on the lattice. Their renormalizations with respect to continuum a…
Four-point renormalized coupling constant and Callan-Symanzik beta-function in O(N) models
A. Pelissetto, E. Vicari
We investigate some issues concerning the zero-momentum four-point renormalized coupling constant g in the symmetric phase of O(N) models, and the corresponding Callan-Symanzik bet…
Can neutron electromagnetic form factors be obtained by polarized inclusive electron scattering off polarized three-nucleon bound states?
A. Kievsky, E. Pace, G. Salme` +1
The investigation of the electromagnetic inclusive responses of polarized He within the plane wave impulse approximation is briefly reported. A particular emphasys is put on…
Improved actions for the two-dimensional sigma-model
Sergio Caracciolo, Andrea Montanari, Andrea Pelissetto
For the O(N) sigma-model we studied the improvement program for actions with two- and four-spin interactions. An interesting example is an action which is reflection-positive, on-s…
