EUV excess in the inner Virgo cluster
F. De Paolis, G. Ingrosso, A. A. Nucita +1
Observations with the Extreme UltraViolet Explorer (EUVE) satellite have shown that the inner region of the Virgo cluster (centered in M87 galaxy) has a strong Extreme UltraViolet…
Charged Higgs Production in the 1 TeV Domain as a Probe of Supersymmetric Models
M. Beccaria, F. M. Renard, S. Trimarchi +1
We consider the production, at future lepton colliders, of charged Higgs pairs in supersymmetric models. Assuming a relatively light SUSY scenario, and working in the MSSM, we show…
Solar neutrino oscillation parameters after first KamLAND results
G. L. Fogli, E. Lisi, A. Marrone +3
We analyze the energy spectrum of reactor neutrino events recently observed in the Kamioka Liquid scintillator Anti-Neutrino Detector (KamLAND) and combine them with solar and terr…
Quaternionic eigenvalue problem
S. De Leo, G. Scolarici, L. Solombrino
We discuss the (right) eigenvalue equation for , and linear quaternionic operators. The possibility to introduce an isomorphism between these…
On the pseudo-Hermitian nondiagonalizable Hamiltonians
G. Scolarici, L. Solombrino
We consider a class of (possibly nondiagonalizable) pseudo-Hermitian operators with discrete spectrum, showing that in no case (unless they are diagonalizable and have a real spect…
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…
Separation of the Longitudinal and Transverse Cross Sections in the p(ee'K)Lambda and p(ee'K)Sigma Reactions
E93018 Collaboration, R. M. Mohring
We report measurements of cross sections for the reaction p(e,e'K)Y, for both the Lambda and Sigma_0 hyperon states, at an invariant mass of W=1.84 GeV and four-momentum transfers…
MGP versus Kochen-Specker condition in hidden variables theories
Claudio Garola
Hidden variables theories for quantum mechanics are usually assumed to satisfy the KS condition. The Bell-Kochen-Specker theorem then shows that these theories are necessarily cont…
On the possibility of measuring relativistic gravitational effects with a LAGEOS-LAGEOS II-OPTIS-mission
Lorenzo Iorio, Ignazio Ciufolini, Erricos Pavlis +3
In this paper we wish to preliminary investigate if it would be possible to use the orbital data from the proposed OPTIS mission together with those from the existing geodetic pass…
Hamiltonian and Potentials in Derivative Pricing Models: Exact Results and Lattice Simulations
Belal E. Baaquie, Claudio Coriano, Marakani Srikant
The pricing of options, warrants and other derivative securities is one of the great success of financial economics. These financial products can be modeled and simulated using qua…
A model for two-proton emission induced by electron scattering
Marta Anguiano, Giampaolo Co', Antonio M. Lallena
A model to study two-proton emission processes induced by electron scattering is developed. The process is induced by one-body electromagnetic operators acting together with short-…
Time-reversal violation as loop-antiloop symmetry breaking: the Bessel equation, group contraction and dissipation
Eleonora Alfinito, Giuseppe Vitiello
We show that the Bessel equation can be cast, by means of suitable transformations, into a system of two damped/amplified parametric oscillator equations. The relation with the gro…
Deformations of plane algebraic curves and integrable systems of hydrodynamic type
Yuji. Kodama, Boris. G. Konopelchenko
We describe our recent work on deformations of hyperelliptic curves by means of integrable hierarchy of hydrodynamic type (nlin.SI/0205012). We also discuss a further extension to…
On the Gravitomagnetic Time Delay
I. Ciufolini, S. Kopeikin, B. Mashhoon +1
We study the gravitational time delay in ray propagation due to rotating masses in the linear approximation of general relativity. Simple expressions are given for the gravitomagne…
Solving Renormalization Group Equations by Recursion Relations
A. Cafarella, C. Coriano', M. Guzzi
Renormalization Group Equations in integro-differential form describing the evolution of cascades or resumming logarithmic scaling violations have been known in quantum field theor…
A note on gravitational wave lensing
F. De Paolis, G. Ingrosso, A. A. Nucita +1
In a recent paper [Ruffa] it was proposed that the massive black hole at the Galactic center may act as a gravitational lens focusing gravitational wave energy to the Earth. Consid…
A Hamiltonian lattice study of the two-dimensional Wess-Zumino model
Matteo Beccaria, Massimo Campostrini, Alessandra Feo
We investigate a Hamiltonian lattice version of the two-dimensional Wess-Zumino model by Quantum Monte Carlo simulations. In order to study the pattern of supersymmetry breaking, w…
Regularization of Legendre Function Series for Charged Particles Improved Nearside-Farside Subamplitudes
R. Anni
A simple regularization procedure is proposed for the Legendre function series of improved nearside-farside subamplitudes for charged particles elastic scattering. The procedure is…
Quantum Mechanics, Path Integrals and Option Pricing: Reducing the Complexity of Finance
Belal E. Baaquie, Claudio Coriano, Marakani Srikant
Quantum Finance represents the synthesis of the techniques of quantum theory (quantum mechanics and quantum field theory) to theoretical and applied finance. After a brief overview…
Superstring Relics, Supersymmetric Fragmentation and UHECR
A. Cafarella, C. Coriano', M. Guzzi +1
Superstring theory predicts the existence of relic metastable particles whose average lifetime is longer than the age of the universe and which could, in principle, be good dark ma…
Wave packets and quantum oscillations
S. De Leo, C. C. Nishi, P. Rotelli
We give a detailed analysis of the oscillation formula within the context of the wave packet formalism. Particular attention is made to insure flavor eigenstate creation in the phy…
