Schwarzschild Field with Maximal Acceleration Corrections
A. Feoli, G. Lambiase, G. Papini +1
We consider a model in which accelerated particles experience line--elements with maximal acceleration corrections. When applied to the Schwarzschild metric, the effective field ex…
Higher-Order Corrections to the Effective Gravitational Action from Noether Symmetry Approach
S. Capozziello, G. Lambiase
Higher-order corrections of Einstein-Hilbert action of general relativity can be recovered by imposing the existence of a Noether symmetry to a class of theories of gravity where R…
Selection Rules in Minisuperspace Quantum Cosmology
S. Capozziello, G. Lambiase
The existence of a Noether symmetry for a given minisuperspace cosmological model is a sort of selection rule to recover classical behaviours in cosmic evolution since oscillatory…
D branes in string theory,I
Paolo Di Vecchia, Antonella Liccardo
In these lectures we present a detailed description of the origin and of the construction of the boundary state that is now widely used for studying the properties of D branes. (Le…
A twisted conformal field theory description of the Quantum Hall Effect
G. Cristofano, G. Maiella, V. Marotta
We construct an effective conformal field theory by using a procedure which induces twisted boundary conditions for the fundamental scalar fields. That allows to describe a quantum…
Bicovariant Calculus in Quantum Theory and a Generalization of the Gauss Law
G. Bimonte, G. Marmo, A. Stern
We construct a deformation of the quantum algebra Fun(T^*G) associated with Lie group G to the case where G is replaced by a quantum group G_q which has a bicovariant calculus. The…
Low momentum nucleon-nucleon potential and shell model effective interactions
Scott Bogner, T. T. S. Kuo, L. Coraggio +2
A low momentum nucleon-nucleon (NN) potential V-low-k is derived from meson exhange potentials by integrating out the model dependent high momentum modes of V_NN. The smooth and ap…
Unstable Heavy Majorana Neutrinos and Leptogenesis
G. Mangano, G. Miele
We propose a new mechanism producing a non-vanishing lepton number asymmetry, based on decays of heavy Majorana neutrinos. If they are produced out of equilibrium, as occurs in pre…
Direct CP violation in K->3pi decays induced by SUSY chromomagnetic penguins
G. D'Ambrosio, G. Isidori, G. Martinelli
An analysis of the CP violating asymmetry in decays in the Standard Model and, by means of the mass insertion approximation, in a wide class of possible supers…
Sequential magnetotunneling in a vertical Quantum Dot tuned at the crossing to higher spin states
B. Jouault, G. Santoro, A. Tagliacozzo
We have calculated the linear magnetoconductance across a vertical parabolic Quantum Dot with a magnetic field in the direction of the current. Gate voltage and magnetic field are…
Measurement of the Probability of Gluon Splitting into Charmed Quarks in Hadronic Z Decays
L3 Collaboration
We have measured the probability, n(g->cc~), of a gluon splitting into a charm-quark pair using 1.7 million hadronic Z decays collected by the L3 detector. Two independent methods…
Neutrino masses and mixings in SO(10)
M. Abud, F. Buccella, D. Falcone +2
Assuming a Zee-like matrix for the right-handed neutrino Majorana masses in the see-saw mechanism, one gets maximal mixing for vacuum solar oscillations, a very small value for $U_…
Search for Extra Dimensions in Boson and Fermion Pair Production in e+e- Interactions at LEP
L3 Collaboration
Extra spatial dimensions are proposed by recent theories that postulate the scale of gravity to be of the same order as the electroweak scale. A sizeable interaction between gravit…

New Gauge Conditions in General Relativity: What Can We Learn from Them?
Giampiero Esposito, Cosimo Stornaiolo
The construction of conformally invariant gauge conditions for Maxwell and Einstein theories on a manifold M is found to involve two basic ingredients. First, covariant derivatives…
Neutrino Oscillations in Brans-Dicke Theory of Gravity
S. Capozziello, G. Lambiase
Flavor oscillations of neutrinos are analyzed in the framework of Brans-Dicke theory of gravity. We find a shift of quantum mechanical phase of neutrino proportional to a…
