Correlation Functions of a Conformal Field Theory in Three Dimensions

S. Guruswamy, P. Vitale

We derive explicit forms of the two--point correlation functions of the $O (N)$ non-linear sigma model at the critical point, in the large $N$ limit, on various three dimensional ma…

Nonleptonic weak decays of charmed mesons

F. Buccella, M. Lusignoli, G. Miele +2

A previous analysis of two-body Cabibbo allowed nonleptonic decays of $D^{0}$ mesons and of Cabibbo allowed and first-forbidden decays of $D^{+}$ and $D_{s}^{+}$ has been adjourned using m…

Form Factor $A_{0} (q^{2})$ , Non Leptonic $D (B) \to P V$ Transitions and Rare $B \to K^{*} γ$ Decays

P. Colangelo, F. De Fazio, P. Santorelli

We use three-point function QCD sum rules to calculate the form factor $A_{0} (q^{2})$ appearing in the matrix element of the flavour-changing axial current between the $D (B)$ state an…

Dynamics of relativistic particle with Lagrangian dependent on acceleration

V. V. Nesterenko, A. Feoli, G. Scarpetta

Models of relativistic particle with Lagrangian $L (k_{1})$ , depending on the curvature of the worldline $k_{1}$ , are considered. By making use of the Frenet basis, the equations…

Finite Fermion Density Effects on the Electroweak String

G. Bimonte, G. Lozano

We consider an Electroweak string in the background of a uniform distribution of cold fermionic matter. As a consequence of the fermion number non-conservation in the Weinberg-Sala…

$K \to π π γ$ decays: a search for novel couplings in kaon decays

Giancarlo D'Ambrosio, Gino Isidori

We analyze $K \to π π γ$ decays in the framework of Chiral Perturbation Theory. We study the different Dalitz plot distributions, trying to find regions where o( $p^{6}$ ) contributions…

Nonclassical Light in Interferometric Measurements

N. A. Ansari, L. Di Fiore, M. A. Man'ko +4

It is shown that the even and odd coherent light and other nonclassical states of light like superposition of coherent states with different phases may replace the squeezed light i…

Energy-Charge Correlation in the $π^{+} π^{-} π^{0}$ Decay of $K_{L}$ and of Tagged Neutral Kaons

F. Buccella, O. Pisanti, F. Sannino

We relate the asymmetries in the charged pions energy in the decay into $π^{+} π^{-} π^{0}$ of $K_{L}$ and of the tagged neutral kaons. The former asymmetry is a given combination of $\Re(ε)…

FQHE and Jain's approach on the torus

G. Cristofano, G. Maiella, R. Musto +1

By using the explicit knowledge of the lowest energy single particle wave functions in the presence of an {\it arbitrary} magnetic field, we extend to the case of a torus Jain's id…

Perturbative Renormalizations of Anyon Quantum Mechanics

G. Amelino-Camelia

In bosonic end perturbative calculations for quantum mechanical anyon systems a regularization and renormalization procedure, analogous to those used in field theory, is necessary.…

O(N) Sigma Model as a Three Dimensional Conformal Field Theory

S. Guruswamy, S. G. Rajeev, P. Vitale

We study a three dimensional conformal field theory in terms of its partition function on arbitrary curved spaces. The large $N$ limit of the nonlinear sigma model at the non-trivi…

Spectral Geometry and One-loop Divergences on Manifolds with Conical Singularities

Dmitri V. Fursaev

Geometrical form of the one-loop divergences induced by conical singularities of background manifolds is studied. To this aim the heat kernel asymptotic expansion on spaces having…

Proton Decay and Neutrino Masses in SO(10)

F. Acampora, G. Amelino-Camelia, F. Buccella +3

In the last few years physicists have been looking at $S O (10)$ GUT models with renewed attention because it has been realized that the SU(5) minimal model cannot unify the strong,…

The one-loop effective action and trace anomaly in four dimensions

A. O. Barvinsky, Yu. V. Gusev, G. A. Vilkovisky +1

The one-loop effective action for a generic set of quantum fields is calculared as a nonlocal expansion in powers of the curvatures (field strengths). This expansion is obtained to…

Semiclassical Gravitational Effects in de Sitter Space at Finite Temperature

D. V. Fursaev, G. Miele

In the framework of finite temperature conformal scalar field theory on de Sitter space-time the linearized Einstein equations for the renormalized stress tensor are exactly solved…

The Zero Tension Limit of The Virasoro Algebra and the Central Extension

F. Lizzi

We argue that the Virasoro algebra for the closed bosonic string can be cast in a form which is suitable for the limit of vanishing string tension. In this form the limit of the Vi…

Distances on a Lattice from Non-commutative Geometry

G. Bimonte, F. Lizzi, G. Sparano

Using the tools of noncommutative geometry we calculate the distances between the points of a lattice on which the usual discretized Dirac operator has been defined. We find that t…

A Field Theory Approach to the $t$ - $J$ Model and the Spin-Charge Separation

Alberto Lerda

We analyze the $t$ - $J$ model using the $CP^{1}$ representation for the slave operators (holons and spinons) which is particularly suited to study the phenomenon of the spin-cha…

Strong rescattering in K-> 3pi decays and low-energy meson dynamics

G. D'Ambrosio, G. Isidori, A. Pugliese +1

We present a consistent analysis of final state interactions in $K \to 3 π$ decays in the framework of Chiral Perturbation Theory. The result is that the kinematical depend…
