Perturbative and Numerical Methods for Stochastic Nonlinear Oscillators
Giseppe Curci, Erika D'Ambrosio
Interferometric gravitational wave detectors are devoted to pick up the effect induced on masses by gravitational waves. The variations of the length dividing two mirrors is measur…
Simulation of Supersymmetric Models with a Local Nicolai Map
Matteo Beccaria, Giuseppe Curci, Erika D'Ambrosio
We study the numerical simulation of supersymmetric models having a local Nicolai map. The mapping can be regarded as a stochastic equation and its numerical integration provides a…
Adaptive Identification of VIRGO-like Noise Spectrum
Elena Cuoco, Giuseppe Curci, Matteo Beccaria
The aim of this work is to show how it is possible to build an on line whitening filter in an adaptive way. We have modeled the VIRGO noise spectrum as an autoregressive stochastic…
Lattice energy-momentum tensor with Symanzik improved actions
A. Buonanno, G. Cella, G. Curci
We define the energy-momentum tensor on lattice for the and for the nonlinear -model Symanzik tree-improved actions, using Ward identities or an explicit matching procedu…
QCD corrections to electroweak processes in an unconventional scheme: application to the b -> s gamma decay
Giancarlo Cella, Giuseppe Curci, Giulia Ricciardi +1
In this work we give a detailed description of a method for the calculation of QCD corrections to electroweak processes in dimensional regularization that does not require any defi…
The SU(3) deconfining phase transition with Symanzik action
G. Cella, G. Curci, A. Vicere' +1
We report on the determination of the deconfining temperature in SU(3) pure gauge theory, using the Symanzik tree level improved action, on lattices of size 3 x 12^3, 4 x 16^3, 5 x…
Numerical simulation of the Kardar-Parisi-Zhang equation
Matteo Beccaria, Giuseppe Curci
We simulate the Kardar-Parisi-Zhang equation in 2+1 dimensions. The Hopf-Cole transformation is used in order to obtain a stable numerical scheme. The two relevant critical exponen…
The b -> s gamma decay revisited
G. Cella, G. Curci, G. Ricciardi +1
In this work we compute the leading logarithmic corrections to the b -> s gamma decay in a dimensional scheme which does not require any definition of the gamma5 matrix. The scheme…
The Kramers equation simulation algorithm II. An application to the Gross-Neveu model
Matteo Beccaria, Giuseppe Curci, Luca Galli
We continue the investigation on the applications of the Kramers equation to the numerical simulation of field theoretic models. In a previous paper we have described the theory an…
The Kramers equation simulation algorithm I. Operator analysis
Matteo Beccaria, Giuseppe Curci
Using an operatorial formalism, we study the Kramers equation and its applications to numerical simulations. We obtain classes of algorithms which may be made precise at every desi…
Scaling, asymptotic scaling and Symanzik improvement. Deconfinement temperature in SU(2) pure gauge theory
Giancarlo cella, Giuseppe Curci, Raffaele Tripiccione +1
We report on a high statistics simulation of SU(2) pure gauge field theory at finite temperature, using Symanzik action. We determine the critical coupling for the deconfinement ph…
QCD non-leading corrections to weak decays in the dimensional scheme
G. Curci, G. Ricciardi
We compute the next to leading QCD corrections to weak four fermion interactions introducing a scheme that does not require an explicit definition of in dimensions. This…
Radiative Correction Effects of a Very Heavy Top
Riccardo Barbieri, Matteo Beccaria, Paolo Ciafaloni +2
If the top is very heavy, m_t >> M_Z, the dominant radiative correction effects in all electroweak precision tests can be exactly characterized in terms of two quantities, the rho-…
