ADM approach to 2+1 dimensional gravity
Pietro Menotti, Domenico Seminara
The canonical ADM equations are solved in terms of the conformal factor in the instantaneous York gauge. A simple derivation is given for the solution of the two body problem. A ge…
Analysis of O(p^2) Corrections to <pi pi|Q_{7,8}|K>
Vincenzo Cirigliano, Eugene Golowich
The one-loop corrections to K->pi and K->2pi matrix elements of the electroweak penguin operator are calculated. General next-to-leading order relations between the K->pi and K->2p…
Phenomenology of deflected anomaly-mediation
Riccardo Rattazzi, Alessandro Strumia, James D. Wells
We explore the phenomenology of a class of models with anomaly-mediated supersymmetry breaking. These models retain the successful flavor properties of the minimal scenario while a…
Synthetic Stellar Clusters for Pop III
G. Raimondo, E. Brocato, S. Cassisi +1
We present preliminary results of an incoming theoretical work concerning the integrated properties of the Population III clusters of stars. On the basis of synthetic Color-Magnitu…
Viscous Flow and Jump Dynamics in Molecular Supercooled Liquids: II Rotations
Cristiano De Michele, Dino Leporini
The rotational dynamics of a supercooled molecular liquid is investigated by a molecular-dynamics numerical study. We detect rotational jumps with a waiting-time distribution which…
Topology in QCD with 4 flavours of dynamical fermions
B. Alles, M. D'Elia, A. Di Giacomo
We study the topological properties of full QCD with four flavours of dynamical staggered fermions. In particular the topological susceptibility is measured and the problem of the…
Are heavy scalars natural in minimal supergravity?
Andrea Romanino, Alessandro Strumia
It has been recently claimed that very large values of a universal soft mass term m_0 for sfermions and higgs bosons become natural when M_top is close to 175 GeV if tanβ\approx 10…
The N-component Ginzburg-Landau Hamiltonian with cubic anisotropy: a six-loop study
J. M. Carmona, A. Pelissetto, E. Vicari
We consider the Ginzburg-Landau Hamiltonian with a cubic-symmetric quartic interaction and compute the renormalization-group functions to six-loop order in d=3. We analyze the stab…
Aharonov-Bohm Effect in the Abelian-Projected SU(3)-QCD with -term
Dmitri Antonov
By making use of the path-integral duality transformation, string representation of the Abelian-projected SU(3)-QCD with the -term is derived. Besides the short-range (self-)int…
Thermal behavior of Quantum Cellular Automaton wires
C. Ungarelli, S. Francaviglia, M. Macucci +1
We investigate the effect of a finite temperature on the behavior of logic circuits based on the principle of Quantum Cellular Automata (QCA) and of ground state computation. In pa…
Bilocal Dynamics for Self-Avoiding Walks
Sergio Caracciolo, Maria Serena Causo, Giovanni Ferraro +2
We introduce several bilocal algorithms for lattice self-avoiding walks that provide reasonable models for the physical kinetics of polymers in the absence of hydrodynamic effects.…
The puzzling theoretical predictions for the luminosity of clumping He burning stars
V. Castellani, S. Degl'Innocenti, L. Girardi +3
This paper deals with theoretical predictions for He burning models in a range of masses covering the so-called Red Giant Branch phase transition. Taking as a guideline the observa…
A Microscopic Look at Liquid Helium: the 3He Impurity Case
A. Polls, A. Fabrocini
The description of the properties of liquid Helium is a challenge for any microscopic many-body theory. In this context, we study the ground state and the excitation spectrum of on…
Confinement, Chiral Symmetry Breaking and Faddeev-Niemi Decomposition in QCD
Kenichi Konishi, Kazunori Takenaga
We identify two distinct, complementary gauge field configurations for QCD with SU(2) gauge group, one (instanton-like configurations) having to do with chiral symmetry breaking bu…
An approach to Mel'nikov theory in celestial mechanics
G. Cicogna, M. Santoprete
Using a completely analytic procedure - based on a suitable extension of a classical method - we discuss an approach to the Poincaré-Mel'nikov theory, which can be conveniently app…
Measurement of the e+e- -> ZZ production cross-section at centre-of-mass energies of 183 and 189GeV
ALEPH Collaboration
The ee -> ZZ cross section at sqrt(s)=182.7 and 188.6 GeV has been measured using the ALEPH detector. The analysis covers all of the visible ZZ final states and yields cross sectio…
Baryogenesis through leptogenesis
Riccardo Barbieri, Paolo Creminelli, Alessandro Strumia +1
Baryogenesis by heavy-neutrino decay and sphaleron reprocessing of both baryon and lepton number is reconsidered, paying special attention to the flavour structure of the general e…
The effective potential of N-vector models: a field-theoretic study to O(ε^3)
A. Pelissetto, E. Vicari
We study the effective potential of three-dimensional O() models. In statistical physics the effective potential represents the free-energy density as a function of the order pa…
Finite size effects and the order of a phase transition in fragmenting nuclear systems
J. M. Carmona, N. Michel, J. Richert +1
We discuss the implications of finite size effects on the determination of the order of a phase transition which may occur in infinite systems. We introduce a specific model to whi…
Correlations and realistic interactions in doubly closed shell nuclei
A. Fabrocini, F. Arias de Saavedra, G. P. Co'
We review the latest variational calculations of the ground state properties of doubly closed shell nuclei, from C to Pb, with semirealistic and realistic two- and t…
Search for Charmless Hadronic Decays of B Mesons with the SLD Detector
SLD Collaboration
Based on a sample of approximately 500,000 hadronic Z0 decays accumulated between 1993 and 1998, the SLD experiment has set limits on 24 fully charged two-body and quasi two-body e…
Stochastic versus dynamic approach to Levy statistics in the presence of an external perturbation
M. Annunziato, P. Grigolini
We study the influence of a dissipation process on diffusion dynamics triggered by slow fluctuations. We study both strong- and weak-friction regime. When the latter regime applies…
Hadron masses and decay constants in quenched QCD
M. Goeckeler, R. Horsley, D. Petters +4
We present results for the mass spectrum and decay constants using non-perturbatively O(a) improved Wilson fermions. Three values of and 30 different quark masses are used to o…
Epsilon' from supersymmetry with non universal A terms?
R. Barbieri, R. Contino, A. Strumia
In supersymmetric theories with a motivated flavour structure, we investigate the possibility that an epsilon' parameter as large as the measured value be generated without conflic…
