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…

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 $Θ$ -term

Dmitri Antonov

By making use of the path-integral duality transformation, string representation of the Abelian-projected SU(3)-QCD with the $Θ$ -term is derived. Besides the short-range (self-)int…

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.…

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…

Photo- and Electro-Disintegration of 3He at Threshold and pd Radiative Capture

M. Viviani, A. Kievsky, L. E. Marcucci +2

The present work reports results for: pd radiative capture observables measured at center-of-mass (c.m.) energies in the range 0--100 keV and at 2 MeV by the TUNL and Wisconsin gro…

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…

Inertial Control of the VIRGO Superattenuator

Giovanni Losurdo

The VIRGO superattenuator (SA) is effective in depressing the seismic noise below the thermal noise level above 4 Hz. On the other hand, the residual mirror motion associated to th…

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…

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 $^{12}$ C to $^{208}$ Pb, with semirealistic and realistic two- and t…

Production of Y(1S) Mesons from chib Decays in pp(bar) Collisions at sqrt(s)=1.8 TeV

CDF Collaboration, T. Affolder

We have reconstructed the radiative decays $χ_{b} (1 P) \to Υ (1 S) γ$ and $χ_{b} (2 P) \to Υ (1 S) γ$ in $p p ˉ$ collisions at $s = 1.8$ TeV, and measured the fraction of $Υ(1S…

Lattice QCD and chiral mesons

Sergio Caracciolo, Fabrizio Palumbo, Roberto Scimia

The standard QCD action is improved by the addition of irrelevant operators built with chiral composites. An effective Lagrangian is derived in terms of auxiliary fields, which has…
