Light-front CQM calculations of baryon electromagnetic form factors
F. Cardarelli, E. Pace, G. Salmé +1
The parameter-free predictions for the and electromagnetic transition form factors, obtained within our light-front constituent quark model us…
Exploring the supersymmetric parameter space by direct search for WIMPs
A. Bottino, F. Donato, G. Mignola +3
It is shown that the new data of the DAMA/NaI detector, combined with recent calculations of nuclear structure functions, provide the most stringent upper bounds on the WIMP-nucleo…
Non Local Observables and Confinement in BF Formulation of Yang-Mills Theory
Francesco Fucito, Maurizio Martellini, Mauro Zeni
The vev's of the magnetic order-disorder operators in QCD are found in an explicit calculation using the first order formulation of Yang-Mills theory.
Non-perturbative renormalization in lattice QCD
G. C. Rossi
In this talk I will discuss a number of approaches designed to deal with the problem of setting up a fully non-perturbative renormalization procedure in lattice QCD. Methods based…
The Beauty of SUSY
A. Masiero, L. Silvestrini
B physics represents a privileged place to look for supersymmetry (SUSY) through its virtual effects. Here we discuss rare B decays (, , …
DIS Structure Functions in Lattice QCD
Stefano Capitani, Giancarlo Rossi
In this talk I present the complete 1-loop perturbative computation of the renormalization constants and mixing coefficients of quark and gluon lattice operators of rank two and th…
Electroproduction of the Roper resonance and the constituent quark model
F. Cardarelli, E. Pace, G. Salme' +1
A parameter-free evaluation of the electromagnetic transition form factors is performed within a light-front constituent quark model, using for the first time th…
Non-perturbative renormalization in kaon decays
A. Donini, V. Giménez, G. Martinelli +4
We discuss the application of the MPSTV non-perturbative method \cite{NPM} to the operators relevant to kaon decays. This enables us to reappraise the long-standing question of the…
Non-leptonic weak decays and final state interactions in lattice QCD
L. Silvestrini
We show that, under a reasonable "smoothness" hypothesis, it is possible to extract informations on the amplitude and phase of two-body non-leptonic weak decay matrix elements from…
QCD at finite temperature and partially negative flavour numbers
G. M. de Divitiis, R. Frezzotti, M. Masetti +1
We study dynamical fermion effects in lattice QCD at finite temperature. The method adopted is basically the extrapolation from negative flavour numbers already tested at zero temp…
Instanton Calculus and Nonperturbative Relations in N=2 Supersymmetric Gauge Theories
Francesco Fucito, Gabriele Travaglini
Using instanton calculus we check, in the weak coupling region, the nonperturbative relation $$ <\Trϕ^2>=iπ\left(\cf-{a\over 2} {\partial\cf\over\partial a}\right)$$ obtained for a…
Evidence for eta prime - pion splitting in unquenched lattice QCD
R. Frezzotti, M. Masetti, R. Petronzio
We perform an extrapolation from negative to positive flavour numbers of full QCD lattice estimates of the mass. The extrapolations are carried out by keeping and mass…
The Chromomagnetic Dipole Operator and the B Semileptonic Branching Ratio
M. Ciuchini, E. Gabrielli, G. F. Giudice
We consider the possibility of having a large branching ratio for the decay coming from an enhanced Wilson coefficient of the chromomagnetic dipole operator. We show tha…
A complete analysis of FCNC and CP constraints in general SUSY extensions of the standard model
F. Gabbiani, E. Gabrielli, A. Masiero +1
We analyze the full set of constraints on gluino- and photino-mediated SUSY contributions to FCNC and CP violating phenomena. We use the mass insertion method, hence providing a mo…
Dynamical flavour dependence of static heavy meson decay constants on the lattice
G. M. de Divitiis, R. Frezzotti, M. Masetti +1
We study the dynamical flavour dependence of the lattice estimates of the heavy meson decay constant in the static limit. We perform the analysis by considering negative flavour nu…
The BF Formalism for QCD and Quark Confinement
F. Fucito, M. Martellini, M. Zeni
Using the BF version of pure Yang-Mills, it is possible to find a covariant representation of the 't Hooft magnetic flux operator. In this framework, 't Hooft's pioneering work on…
Testing Theories of Gravity with a Spherical Gravitational Wave Detector
M. Bianchi, E. Coccia, C. N. Colacino +2
We consider the possibility of discriminating different theories of gravity using a recently proposed gravitational wave detector of spherical shape. We argue that the spin content…
Open Superstrings
Gianfranco Pradisi
We review the basic principles of the construction of open and unoriented superstring models and analyze some representative examples.
Two-body non-leptonic decays on the lattice
M. Ciuchini, E. Franco, G. Martinelli +1
We show that, under reasonable hypotheses, it is possible to study two-body non-leptonic weak decays in numerical simulations of lattice QCD. By assuming that final-state interacti…
Pseudofermion observables for static heavy meson decay constants on the lattice
G. M. de Divitiis, R. Frezzotti, M. Masetti +1
A method based on the Monte Carlo inversion of the Dirac operator on the lattice provides low noise results for the correlations entering the definition of the heavy meson decay co…
Explicit Construction of Yang-Mills Instantons on ALE Spaces
Massimo Bianchi, Francesco Fucito, Maurizio Martellini +1
We describe the explicit construction of Yang-Mills instantons on ALE spaces, following the work of Kronheimer and Nakajima. For multicenter ALE metrics, we determine the abelian i…
