Further Comments on a Vanishing Singlet Axial Vector Charge
T. P. Cheng, N. I. Kochelev, V. Vento
The recent suggestion of a vanishing flavor-singlet axial charge of nucleon due to a nontrivial vacuum structure is further amplified. A perturbative QCD discussion, applicable for…
Predicted HST FOC and broad band colours for young and intermediate Simple Stellar Populations
E. Brocato, V. Castellani, G. Raimondo +1
This paper presents theoretical HST and broad band colours from population synthesis models based on an homogeneous set of stellar evolutionary tracks as computed under canonical (…
Limits on dark matter WIMPs using upward-going muons in the MACRO detector
The MACRO Collaboration, M. Ambrosio et al
We perform an indirect search for Weakly Interacting Massive Particles (WIMPs) using the MACRO detector to look for neutrino-induced upward-going muons resulting from the annihilat…
Theoretical stellar models for old galactic clusters
V. Castellani, S. Degl'Innocenti, M. Marconi
We present new evolutionary stellar models suitable for old Population I clusters, discussing both the consequences of the most recent improvements in the input physics and the eff…
Intermittency and scaling laws for wall bounded turbulence
R. Benzi, G. Amati, C. M. Casciola +2
Well defined scaling laws clearly appear in wall bounded turbulence, even very close to the wall, where a distinct violation of the refined Kolmogorov similarity hypothesis (RKSH)…
Multiscale velocity correlation in turbulence: experiments, numerical simulations, synthetic signals
R. Benzi, L. Biferale, G. Ruiz-Chavarria +2
Multiscale correlation functions in high Reynolds number experimental turbulence, numerical simulations and synthetic signals are investigated. Fusion Rules predictions as they ari…
The Nonlinear Schrodinger Equation on the Half Line
M. Gattobigio, A. Liguori, M. Mintchev
The nonlinear Schrodinger equation on the half line with mixed boundary condition is investigated. After a brief introduction to the corresponding classical boundary value problem,…
Galactic Globular Cluster Stars: from Theory to Observation
S. Cassisi, V. Castellani, S. Degl'Innocenti +2
We use evolutionary calculations presented in a recent paper (Cassisi et al. 1998) to predict B,V,I magnitudes for stars in galactic globulars. The effect of the adopted mixing len…
Gauge-invariant nonlocal quark condensates in QCD
M. D'Elia, A. Di Giacomo, E. Meggiolaro
We study, by numerical simulations on a lattice, the behaviour of the gauge-invariant nonlocal quark condensates in the QCD vacuum both in the quenched approximation and with four…
Bubble-nucleation rates for radiatively induced first-order phase transitions
Alessandro Strumia, Nikolaos Tetradis
We present a consistent calculation of bubble-nucleation rates in theories of two scalar fields. Our approach is based on the notion of a coarse-grained free energy that incorporat…
Natural ranges of supersymmetric signals
L. Giusti, A. Romanino, A. Strumia
The LEP2 experiments pose a serious naturalness problem for supersymmetric models. The problem is stronger in gauge mediation than in supergravity models. Particular scenarios, lik…
Fractional Calculus as a Macroscopic Manifestation of Randomness
P. Grigolini, A. Rocco, B. J. West
We generalize the method of Van Hove so as to deal with the case of non-ordinary statistical mechanics, that being phenomena with no time-scale separation. We show that in the case…
Regge-Liouville action from group theory
P. Menotti
We work out the constraints imposed by SL(2C) invariance for sphere topology and modular invariance for torus topology, on the discretized form of Liouville action in Polyakov's no…
Bounds on hep neutrinos
G. Fiorentini, V. Berezinsky, S. Degl'Innocenti +1
The excess of highest energy solar-neutrino events recently observed by Superkamiokande can be in principle explained by anomalously high -neutrino flux . Without us…
Strange Stars with Realistic Quark Vector Interaction and Phenomenological Density-dependent Scalar Potential
Mira Dey, Ignazio Bombaci, Jishnu Dey +2
We derive an equation of state (EOS) for strange matter, starting from an interquark potential which (i) has asymptotic freedom built into it, (ii) shows confinement at zero baryon…
Mass spectrum and decay constants in the continuum limit
M. Goeckeler, R. Horsley, V. Linke +6
We present first results for light hadron masses, quark masses and decay constants in the continuum limit using O(a) improved fermions at three different values of the gauge coupli…
The leading chiral electromagnetic correction to the nonleptonic Delta I = 3/2 amplitude in kaon decays
Vincenzo Cirigliano, John F. Donoghue, Eugene Golowich
In kaon decay, electromagnetic radiative corrections can generate shifts in the apparent Delta I = 3/2 amplitude of order alpha A_0/A_2 ~ 22 alpha. In order to know the true Delta…
Branched Spines and Contact Structures on 3-manifolds
Riccardo Benedetti, Carlo Petronio
We introduce and analyze the characteristic foliation induced by a contact structure on a branched surface, in particular a branched standard spine of a 3-manifold. We extend to (f…
Oscillation Frequencies for a Bose Condensate in a Triaxial Magnetic Trap
E. Cerboneschi, R. Mannella, E. Arimondo +1
We investigate the dynamics of a Bose condensate, interacting with either repulsive or attractive forces, confined in a fully anisotropic harmonic potential. The (3+1)-dimensional…
Nucleon form factors and O(a) Improvement
S. Capitani, M. Gockeler, R. Horsley +9
Nucleon form factors have been extensively studied both experimentally and theoretically for many years. We report here on new results of a high statistics quenched lattice QCD cal…
Resolving Exceptional Configurations in Quenched Lattice QCD
M. Göckeler, A. Hoferichter, R. Horsley +4
Quenched lattice QCD calculations with Wilson-type fermions at small quark masses are impeded by exceptional configurations. We show how this problem can be resolved in a practicab…
Putting centre dominance under the microscope
P. W. Stephenson
We make various short points on the phenomenon of centre dominance in SU(2). The Z(2) dominance seen in Wilson loops is related to the loop distribution and to half-odd-integer rep…
Crossover scaling from classical to non-classical critical behaviour
Sergio Caracciolo, Maria Serena Causo, Andrea Pelissetto +2
Interacting physical systems in the neighborhood of criticality (and massive continuum field theories) can often be characterized by just two physical scales: a (macroscopic) corre…
Operator product expansion and non-perturbative renormalization
Sergio Caracciolo, Andrea Montanari, Andrea Pelissetto
It has been recently proposed to use the operator product expansion to evaluate the expectation values of renormalized operators without the need of a direct computation of the rel…
