Muon anomalous magnetic moment in a Calculable Model with one Extra Dimension

Giacomo Cacciapaglia, Marco Cirelli, Giampaolo Cristadoro

In the framework of a recently proposed extension of the Standard Model, with N=1 SuperSymmetry in 5 dimensions, compactified on R^1/(Z_2 x Z'_2), we compute the muon anomalous mag…

Modeling the Galactic Center Nonthermal Filaments as Magnetized Wake

Russell B. Dahlburg, Giorgio Einaudi, T. N. LaRosa +1

We simulate the Galactic Center nonthermal filaments as magnetized wakes formed dynamically from amplification of a weak (tens of $μ$ G) global magnetic field through the interactio…

The tricky galactic cluster NGC2420

P. G. Prada Moroni, V. Castellani, S. Degl'Innocenti +1

We discuss the CM diagram of the galactic cluster NGC2420 to the light of current theoretical predictions. By relying on the most recent updating of the physical input, one finds t…

Strange kinetics: conflict between density and trajectory description

M. Bologna, P. Grigolini, B. J. West

We study a process of anomalous diffusion, based on intermittent velocity fluctuations, and we show that its scaling depends on whether we observe the motion of many independent tr…

The stellar content of the Galaxy: the white dwarf population

M. Cignoni, V. Castellani, S. Degl'Innocenti +2

On the basis of theoretical evolutionary expectations, we develop a Galactic model reproducing star counts and synthetic color-magnitude diagrams of field stars, which include the…

Asymptotic Giant Branch predictions: theoretical uncertainties

S. Cassisi, V. Castellani, S. Degl'Innocenti +2

In this paper we investigate the level of agreement between observations and "new" Asymptotic Giant Branch (AGB) models, as produced by updating the physical inputs adopted in prev…

Oxygen and nitrogen abundances in Virgo and field spirals

L. S. Pilyugin, Mercedes Molla, Federico Ferrini +1

The oxygen and nitrogen abundances in the HII regions of the nine Virgo spirals of the sample from Skillman et al (1996) and in nine field spiral galaxies are re-determined with th…

Theoretical Study of the ^3He(mu^-,nu_mu)^3H Capture

L. E. Marcucci, R. Schiavilla, S. Rosati +2

The ^3He(mu^-,nu_mu)^3H weak capture is studied using correlated-hyperspherical-harmonics wave functions, obtained from realistic Hamiltonians consisting of the Argonne $v_{14}$ or…

Chaos in Black holes Surrounded by Electromagnetic Fields

Manuele Santoprete, Giampaolo Cicogna

In this paper we prove the occurence of chaos for charged particles moving around a Schwarzshild black hole, perturbed by uniform electric and magnetic fields. The appearance of ch…

Some Comments on N=1 Gauge Theories from Wrapped Branes

R. Apreda, F. Bigazzi, A. L. Cotrone +2

We discuss various aspects of gauge theories realized on the world-volume of wrapped branes. In particular we analyze the coupling of SYM operators to space-time fields both in N=1…

Correlation functions for a Bose-Einstein condensate in the Bogoliubov approximation

A. Montina, E. Arimondo

In this article we introduce a differential equation for the first order correlation function $G^{(1)}$ of a Bose-Einstein condensate at T=0. The Bogoliubov approximation is used.…

Direct CP Violation Searches in Charmless Hadronic B Meson Decays

The BABAR Collaboration, B. Aubert

We search for direct CP violation in charmless hadronic B decays observed in a sample of about 22.7 million $B B ˉ$ pairs collected with the BABAR detector at the PEP-II asymmet…

Aging Induced Multifractality

P. Allegrini, J. Bellazzini, G. Bramanti +3

We show that the dynamic approach to Lévy statistics is characterized by aging and multifractality, induced by an ultra-slow transition to anomalous scaling. We argue that these as…

Structure factor of dilute ring polymers

Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari

We consider ring polymers in good solvents in the dilute limit. We determine the structure factor and the monomer-monomer distribution function. We compute accurately the asymptoti…

Renormalization-group flow in the 3D Georgi-Glashow model

Dmitri Antonov

The renormalization-group (RG) flow in the finite-temperature (2+1)-dimensional Georgi-Glashow model is explored. This is done in the limit when the squared electric coupling const…
