The residual mass in Lattice Heavy Quark Effective Theory to alpha^3 order
F. Di Renzo, L. Scorzato
We determine to order alpha^3 in the quenched approximation the so-called residual mass in the lattice regularisation of the Heavy Quark Effective Theory. We follow a gauge-invaria…
A consistency check for Renormalons in Lattice Gauge Theory: beta^(-10) contributions to the SU(3) plaquette
F. Di Renzo, L. Scorzato
We compute the perturbative expansion of the Lattice SU(3) plaquette to beta^(-10) order. The result is found to be consistent both with the expected renormalon behaviour and with…
Probability density of determinants of random matrices
Giovanni M. Cicuta, Madan L. Mehta
In this brief paper the probability density of a random real, complex and quaternion determinant is rederived using singular values. The behaviour of suitably rescaled random deter…
Matrix model formulation of four dimensional gravity
R. De Pietri
The attempt of extending to higher dimensions the matrix model formulation of two-dimensional quantum gravity leads to the consideration of higher rank tensor models. We discuss ho…
Fermionic Loops in Numerical Stochastic Perturbation Theory
F. Di Renzo, L. Scorzato
We discuss the inclusion of fermionic loops contributions in Numerical Stochastic Perturbation Theory for Lattice Gauge Theories. We show how the algorithm implementation is in pri…
Non-Linear Evolution of the r-Modes in Neutron Stars
Lee Lindblom, Joel E. Tohline, Michele Vallisneri
The evolution of a neutron-star r-mode driven unstable by gravitational radiation (GR) is studied here using numerical solutions of the full non-linear fluid equations. The amplitu…
Multiple vacua in two-dimensional Yang-Mills theory
A. Bassetto, L. Griguolo, F. Vian
Two-dimensional SU(N) Yang-Mills theory is endowed with a non-trivial vacuum structure (k-sectors). The presence of k-sectors modifies the energy spectrum of the theory and its ins…
Landau levels on a torus
Enrico Onofri
Landau levels have represented a very rich field of research, which has gained widespread attention after their application to quantum Hall effect. In a particular gauge, the holom…
Testing CP Conservation at KLOE
Giuseppe Mambriani, Luca Trentadue
A proposal for maintaining CP conservation in decays is resumed, by adding a heterodox hypothesis. One recovers a consistent picture with a decay branc…
Fine-tuning and the Wilson renormalization group
M. Bonini, E. Tricarico
We use the Wilson renormalization group (RG) formulation to solve the fine-tuning procedure needed in renormalization schemes breaking the gauge symmetry. To illustrate this method…
Axial Anomaly Effects in Pion and Radiative Decays
Luca Trentadue, Michela Verbeni
We discuss a connection between axial anomaly and polarized radiative processes. By comparison with the corresponding unpolarized cases, we consider some physical outputs for the $…
Quasi-normal modes of charged, dilaton black holes
Valeria Ferrari, Massimo Pauri, Federico Piazza
In this paper we study the perturbations of the charged, dilaton black hole, described by the solution of the low energy limit of the superstring action found by Garfinkle, Horowit…
Relaxing Near the Critical Point
D. Boyanovsky, H. J. de Vega, M. Simionato
Critical slowing down of the relaxation of the order parameter is relevant both in early the universe and in ultrarelativistic heavy ion collisions. We study the relaxation rate of…
Feynman Diagrams of Generalized Matrix Models and the Associated Manifolds in Dimension 4
Roberto De Pietri, Carlo Petronio
The problem of constructing a quantum theory of gravity has been tackled with very different strategies, most of which relying on the interplay between ideas from physics and from…
Axial Anomaly and Polarized Radiative Decays
Luca Trentadue, Michela Verbeni
We extend the approach of Dolgov and Zakharov to the axial anomaly to study polarized radiative decays. We analyse the pattern of mass singularity cancellation in the corresponding…
Lattice calculation of corrections to and of in the scheme
Ph. Boucaud, G. Burgio, F. Di Renzo +8
We report on very strong evidence of the occurrence of power terms in $\as(p)$, the QCD running coupling constant in the scheme, by analyzing non-perturbative mea…
Radiative Corrections to the Hadronic Cross-Section Measurement at DAPHNE
V. A. Khoze, M. I. Konchatnij, N. P. Merenkov +3
The hadronic invariant mass distribution for the process of electron-positron annihilation into a pair of charged pions accompanied by a photon radiated from the initial state has…
Understanding stochastic perturbation theory: toy models and statistical analysis
R. Alfieri, F. Di Renzo, E. Onofri +1
The numerical stochastic perturbation method based on Parisi-Wu quantisation is applied to a suite of simple models to test its validity at high orders. Large deviations from norma…
Wilson loops in the adjoint representation and multiple vacua in two-dimensional Yang-Mills theory
A. Bassetto, L. Griguolo, F. Vian
with fermions in the adjoint representation is invariant under and thereby is endowed with a non-trivial vacuum structure (k-sectors). The static potential betw…
