On the continuity of the solution operator to the wave map system
Piero D'Ancona, Vladimir Georgiev
We investigate the continuity properties of the solution operator to the wave map system from the flat Minkowski space to a general nonflat target of arbitrary dimension, and we pr…
Field-theory results for three-dimensional transitions with complex symmetries
Pasquale Calabrese, Andrea Pelissetto, Paolo Rossi +1
We discuss several examples of three-dimensional critical phenomena that can be described by Landau-Ginzburg-Wilson theories. We present an overview of field-theoretical resu…
On the evaluation of the improvement parameter in the lattice Hamiltonian approach to critical phenomena
Massimo Campostrini, Pietro Parruccini, Paolo Rossi
In lattice Hamiltonian systems with a quartic coupling , a critical value may exist such that, when , the leading irrelevant operator decouples from the Hamiltonian…
Variable stars in Stellar Systems
Giuseppe Bono, Silvia Petroni, Marcella Marconi
We discuss in detail the pulsation properties of variable stars in globular clusters (GCs) and in Local Group (LG) dwarf galaxies. Data available in the literature strongly support…
Simultaneous Measurement of the B0 Meson Lifetime and Mixing Frequency with B0 --> D*- l+ nu Decays
the BABAR Collaboration, B. Aubert
We measure the B0 lifetime τ_{B0} and the B0-B0bar oscillation frequency Δm_d with a sample of approximately 14,000 exclusively reconstructed B0 --> D*- l+ nu signal events, select…
Measurement of the B0 meson lifetime with partial reconstruction of B0 --> D*- pi+ and B0 --> D*- rho+ decays
The BABAR Collaboration, B. Aubert
The neutral meson lifetime is measured with the data collected by the BaBar detector at the PEP-II storage ring during the years 1999 and 2000, with a total integrated luminosi…
Three-Nucleon Electroweak Capture Reactions
L. E. Marcucci, M. Viviani, A. Kievsky +2
Recent advances in the study of the p-d radiative and mu-3he weak capture processes are presented and discussed. The three-nucleon bound and scattering states are obtained using th…
Fast Monte Carlo simulations and singularities in the probability distributions of non-equilibrium systems
A. Bandrivskyy, S. Beri, D. G. Luchinsky +2
A numerical technique is introduced that reduces exponentially the time required for Monte Carlo simulations of non-equilibrium systems. Results for the quasi-stationary probabilit…
Mathematical structure of the temporal gauge
J. Loeffelholz, G. Morchio, F. Strocchi
The mathematical structure of the temporal gauge of QED is critically examined in both the alternative formulations characterized by either positivity or regularity of the Weyl alg…
Absence of higher derivatives in the renormalization of propagators in quantum field theories with infinitely many couplings
Damiano Anselmi
I study some aspects of the renormalization of quantum field theories with infinitely many couplings in arbitrary space-time dimensions. I prove that when the space-time manifold a…
Power-Law Time Distribution of Large Earthquakes
Mirko S. Mega, Paolo Allegrini, Paolo Grigolini +4
We study the statistical properties of time distribution of seimicity in California by means of a new method of analysis, the Diffusion Entropy. We find that the distribution of ti…
A simplified numerical model of coronal energy dissipation based on reduced MHD
E. Buchlin, V. Aletti, S. Galtier +3
A 3D model intermediate between cellular automata (CA) models and the reduced magnetohydrodynamic (RMHD) equations is presented to simulate solar impulsive events generated along a…
Almost Conformal Vacua and Confinement
Roberto Auzzi, Roberto Grena, Kenichi Konishi
Dynamics of confining vacua which appear as deformed superconformal theory with a non-Abelian gauge symmetry, is studied by taking a concrete example of the sextet vacua of ${\cal…
Transverse Fluctuations in the Driven Lattice Gas
Sergio Caracciolo, Andrea Gambassi, Massimiliano Gubinelli +1
We define a transverse correlation length suitable to discuss the finite-size-scaling behavior of an out-of-equilibrium lattice gas, whose correlation functions decay algebraically…
Harmonic generation by atoms in circularly polarized two-color laser fields with coplanar polarizations and commensurate frequencies
F. Ceccherini, D. Bauer, F. Cornolti
The generation of harmonics by atoms or ions in a two-color, coplanar field configuration with commensurate frequencies is investigated through both, an analytical calculation base…
Three Dimensional Relativistic Electromagnetic Sub-cycle Solitons
Timur Esirkepov, Katsunobu Nishihara, Sergei V. Bulanov +1
Three dimensional (3D) relativistic electromagnetic sub-cycle solitons were observed in 3D Particle-in-Cell simulations of an intense short laser pulse propagation in an underdense…
The Second Moment of the Pion Light Cone Wave Function
Luigi Del Debbio, Massimo Di Pierro, Alex Dougall
We present a preliminary result for second moment of the light cone wave function of the pion. This parameter is the subject of a discrepancy between theoretical predictions (comin…
IIB Soliton Spectra with All Fluxes Activated
Jarah Evslin
Building upon an earlier proposal for the classification of fluxes, a sequence is proposed which generalizes the AHSS by computing type IIB string theory's group of conserved RR an…
The Search for the Sidereal and Solar Diurnal Modulations in the Total MACRO Muon Data Set
The MACRO Collaboration, M. Ambrosio
We have analyzed 44.3M single muons collected by MACRO from 1991 through 2000 in 2,145 live days of operation. We have searched for the solar diurnal, apparent sidereal, and pseudo…
Tight, not semi--fillable contact circle bundles
Paolo Lisca, Andras I. Stipsicz
Extending our earlier results, we prove that certain tight contact structures on circle bundles over surfaces are not symplectically semi--fillable, thus confirming a conjecture of…
Non-orientable 3-manifolds of small complexity
Gennaro Amendola, Bruno Martelli
We classify all closed non-orientable P2-irreducible 3-manifolds having complexity up to 6 and we describe some having complexity 7. We show in particular that there is no such man…
Adaptive spectral identification techniques in presence of undetected non linearities
G. Cella, E. Cuoco, G. M. Guidi
The standard procedure for detection of gravitational wave coalescing binaries signals is based on Wiener filtering with an appropriate bank of template filters. This is the optima…
"Integrability" of RG flows and duality in three dimensions in the 1/N expansion
D. Anselmi
I study some classes of RG flows in three dimensions that are classically conformal and have manifest g -> 1/g dualities. The RG flow interpolates between known (four-fermion, Wils…
Higgs- and quark-inspired modifications of the finite-temperature properties of the Polyakov model
D. Antonov
(2+1)-dimensional Georgi-Glashow model, else called the Polyakov model, is explored at nonzero temperatures and in the regime when the Higgs boson is not infinitely heavy. The fini…
