Leading Logarithms in Field Theory
U. Aglietti, G. Corbo`, L. Trentadue
We consider the Sudakov form factor in effective theories and we show that one can derive correctly the double logarithms of the original, high-energy, theory. We show that in effe…
Cutting-Decimation Renormalization for diffusive and vibrational dynamics on fractals
Raffaella Burioni, Davide Cassi, Sofia Regina
Recently, we pointed out that on a class on non exactly decimable fractals two different parameters are required to describe diffusive and vibrational dynamics. This phenomenon we…
Cut Vertices and Semi-Inclusive Deep Inelastic Processes
M. Grazzini
Cut vertices, a generalization of matrix elements of local operators, are revisited, and an expansion in terms of minimally subtracted cut vertices is formulated. An extension of t…
Semi-Inclusive DIS: an explicit calculation in the Target Fragmentation Region
M. Grazzini
I present a calculation of the one particle deep inelastic cross section in the target fragmentation region in (ϕ^3)_6. The renormalized cross section gets a large logarithmic corr…
Fracture functions from cut vertices
M. Grazzini, L. Trentadue, G. Veneziano
Using a generalized cut vertex expansion we introduce the concept of an extended fracture function for the description of semi-inclusive deep inelastic processes in the target frag…
Developments and new applications of numerical stochastic perturbation theory
G. Burgio, F. Di Renzo, G. Marchesini +3
A review of new developments in numerical stochastic perturbation theory (NSPT) is presented. In particular, the status of the extension of the method to gauge fixed lattice QCD is…
Power corrections and perturbative coupling from lattice gauge thoeries
G. Burgio, F. Di Renzo, G. Marchesini +1
From the analysis of the perturbative expansion of the lattice regularized gluon condensate, toghether with MC data, we present evidence of OPE-unexpected dim-2 power corrections i…
One particle cross section in the target fragmentation region: an explicit calculation in (ϕ^3)_6
M. Grazzini
One particle inclusive cross sections in the target fragmentation region are considered and an explicit calculation is performed in (ϕ^3)_6 model field theory. The collinear diverg…
Chiral gauge theories and anomalies in the Wilson renormalization group approach
M. Bonini, F. Vian
We extend the Wilson renormalization group (RG) formulation to chiral gauge theories and show that local gauge symmetry can be implemented by a suitable choice of the RG flow bound…
Lambda^2-contribution to the condensate in lattice gauge theory
G. Burgio, F. Di Renzo, G. Marchesini +1
We present some evidence that in Lattice Gauge Theory the condensate contains a non-perturbative contribution proportional to , the square of the physical scale. This result i…
Matrix Elements of Thiemann's Hamiltonian Constraint in Loop Quantum Gravity
Roumen Borissov, Roberto De Pietri, Carlo Rovelli
We present an explicit computation of matrix elements of the hamiltonian constraint operator in non-perturbative quantum gravity. In particular, we consider the euclidean term of T…
Large angle QED processes at e^+e^- colliders at energies below 3 GeV
A. B. Arbuzov, G. V. Fedotovich, E. A. Kuraev +3
QED processes at electron-positron colliders are considerd. We present differential cross-sections for large-angle Bhabha scattering, annihilation into muons and photons. Radiative…
Spin Networks and Recoupling in Loop Quantum Gravity
Roberto De Pietri
I discuss the role played by the spin-network basis and recoupling theory (in its graphical tangle-theoretic formulation) and their use for performing explicit calculations in loop…
