Enriques and Octonionic Magic Supergravity Models
Massimo Bianchi, Sergio Ferrara
We reconsider the Enriques Calabi Yau (FHSV) model and its string derivation and argue that the Octonionic magic supergravity theory admits a string interpretation closely related…
Non-perturbative renormalisation of Delta F=2 four-fermion operators in two-flavour QCD
P. Dimopoulos, G. Herdoiza, F. Palombi +4
Using Schroedinger Functional methods, we compute the non-perturbative renormalisation and renormalisation group running of several four-fermion operators, in the framework of latt…
Relativistic Hamiltonian Dynamics and Few-Nucleon Systems
F. A. Baroncini, E. Pace, G. Salme`
We present a preliminary calculation of the electromagnetic form factors of He and H, performed within the Light-Front Hamiltonian Dynamics. Relativistic effects show their…
Upper limit on the diffuse flux of UHE tau neutrinos from the Pierre Auger Observatory
The Pierre Auger Collaboration
The surface detector array of the Pierre Auger Observatory is sensitive to Earth-skimming tau-neutrinos that interact in the Earth's crust. Tau leptons from charged-cur…
Temperature and Humidity Dependence of Air Fluorescence Yield measured by AIRFLY
M. Ave
The fluorescence detection of ultra high energy cosmic rays requires a detailed knowledge of the fluorescence light emission from nitrogen molecules over a wide range of atmospheri…
Large tan(beta) effects in flavour physics
Gino Isidori
After a short introduction to the SUSY flavour problem, we focus the attention on the MSSM with MFV and large . The theoretical motivations and the general features of this…
(1+1)-dimensional separation of variables
Giuseppe Pucacco, Kjell Rosquist
In this paper we explore general conditions which guarantee that the geodesic flow on a 2-dimensional manifold with indefinite signature is locally separable. This is equivalent to…
First joint Gravitational Waves search by the Auriga-Explorer-Nautilus-Virgo collaboration
Virgo collaboration
We present results of the search for coincident burst excitations over a 24 hours long data set collected by AURIGA, EXPLORER, NAUTILUS and Virgo detectors during September 2005. T…
Precision for B-meson matrix elements
Damiano Guazzini, Rainer Sommer, Nazario Tantalo
We demonstrate how HQET and the Step Scaling Method for B-physics, pioneered by the Tor Vergata group, can be combined to reach a further improved precision. The observables consid…
A Study of the Radiative Ke3 Decay and Search for Direct Photon Emission with the KLOE Detector
Kloe Collaboration
We present a measurement of the ratio R = Γ(\keg;\Estar>30\mev,\qstar>20^\circ)Γ(\kegf)$ and a first measurement of the direct emission contribution in KL semileptonic decays. T…
Light quark masses and pseudoscalar decay constants from Nf=2 Lattice QCD with twisted mass fermions
B. Blossier, Ph. Boucaud, P. Dimopoulos +15
We present the results of a lattice QCD calculation of the average up-down and strange quark masses and of the light meson pseudoscalar decay constants with Nf=2 dynamical fermions…
All-sky incoherent search for periodic signals with Explorer 2005 data
P. Astone, D. Babusci, M. Bassan +31
The data collected during 2005 by the resonant bar Explorer are divided into segments and incoherently summed in order to perform an all-sky search for periodic gravitational wave…
The ALTCRISS project on board the International Space Station
M. Casolino, F. Altamura, M. Minori +19
The Altcriss project aims to perform a long term survey of the radiation environment on board the International Space Station. Measurements are being performed with active and pass…
Peculiar acceleration
Luca Amendola, Claudia Quercellini, Amedeo Balbi
It has been proposed recently to observe the change in cosmological redshift of distant galaxies or quasars with the next generation of large telescope and ultra-stable spectrograp…
The ATLAS Level-1 Trigger: Status of the System and First Results from Cosmic-Ray Data
David Berge
The ATLAS detector at CERN's Large Hadron Collider (LHC) will be exposed to proton-proton collisions from beams crossing at 40 MHz. At the design luminosity of 10^34 cm^-2 s^-1 the…
Search for the K(S) --> e+e- decay with the KLOE detector at DAFNE
The KLOE collaboration
We present results of a direct search for the decay KS --> e+e- with the KLOE detector, obtained with a sample of e+e- --> phi --> KSKL events produced at DAFNE, the Frascati phi-f…
Measurement of eta photoproduction on the proton from threshold to 1500 MeV
O. Bartalini, V. Bellini, J. P. Bocquet +39
Beam asymmetry and differential cross section for the reaction gamma+p->eta+p were measured from production threshold to 1500 MeV photon laboratory energy. The two dominant neutral…
On the Orbit Structure of the Logarithmic Potential
Cinzia Belmonte, Dino Boccaletti, Giuseppe Pucacco
We investigate the dynamics in the logarithmic galactic potential with an analytical approach. The phase-space structure of the real system is approximated with resonant detuned no…
N=1* model superpotential revisited (IR behaviour of N=4 limit)
S. Arnone, G. Di Segni, M. Siccardi +1
The one-loop contribution to the superpotential, in particular the Veneziano-Yankielowicz potential in N=1 supersymmetric Yang-Mills model is discussed from an elementary field the…
Real Forms of Complex Higher Spin Field Equations and New Exact Solutions
Carlo Iazeolla, Ergin Sezgin, Per Sundell
We formulate four dimensional higher spin gauge theories in spacetimes with signature (4-p,p) and nonvanishing cosmological constant. Among them are chiral models in Euclidean (4,0…
Affine equation of state from quintessence and k-essence fields
Claudia Quercellini, Marco Bruni, Amedeo Balbi
We explore the possibility that a scalar field with appropriate Lagrangian can mimic a perfect fluid with an affine barotropic equation of state. The latter can be thought of as a…
