A precise determination of in quenched QCD
P. Dimopoulos, J. Heitger, F. Palombi +3
The parameter is computed in quenched lattice QCD with Wilson twisted mass fermions. Two variants of tmQCD are used; in both of them the relevant four-fermion operat…
Eta photoproduction off the neutron at GRAAL
V. Kuznetsov, O. Bartalini, V. Bellini +24
The gamma n -> eta n quasi-free cross section reveals a resonant structure at W ~ 1.675 GeV. This structure may be a manifestation of a baryon resonance. A priori its properties, t…
Stability of lattice QCD simulations and the thermodynamic limit
L. Del Debbio, L. Giusti, M. Lüscher +2
We study the spectral gap of the Wilson--Dirac operator in two-flavour lattice QCD as a function of the lattice spacing , the space-time volume and the current-quark mass $m…
The integrated bispectrum as a test of CMB non-Gaussianity: detection power and limits on f_NL with WMAP data
P. Cabella, F. K. Hansen, M. Liguori +4
We propose a fast and efficient bispectrum statistic for Cosmic Microwave Background (CMB) temperature anisotropies to constrain the amplitude of the primordial non-Gaussian signal…
D-brane dynamics in a plane wave background
J. Kluson, Rashmi R. Nayak, Kamal L. Panigrahi
By using the Dirac-Born-Infeld action we study the dynamics of Dp-brane propagating in the NS5-near horizon plane wave background. We study systematically D-brane embedding in this…
N=1 Superpotentials from Multi-Instanton Calculus
F. Fucito, J. F. Morales, R. Poghossian +1
In this paper we compute gaugino and scalar condensates in N=1 supersymmetric gauge theories with and without massive adjoint matter, using localization formulae over the multi--in…
Investigating pseudoscalar and scalar dark matter
R. Bernabei, P. Belli, F. Montecchia +10
In this paper another class of Dark Matter candidate particles: the pseudoscalar and scalar light bosonic candidates, is discussed. Particular care is devoted to the study of the p…
Probing New Physics through mu-e Universality in K->lnu
A. Masiero, P. Paradisi, R. Petronzio
The recent NA48/2 improvement on R_K=Gamma(K->e nu_e)/Gamma(K->mu nu_mu) emphasizes the role of K_l2 decays in probing the mu-e universality. Supersymmetric (SUSY) extensions of th…
Strings on AdS_3 x S^3 and the Plane-Wave Limit. Issues on PP-Wave/CFT Holography
Oswaldo Zapata
In this thesis we give explicit results for bosonic string amplitudes on AdS_3 x S^3 and the corresponding plane-wave limit. We also analyze the consequences of our approach for un…
Four quark operators in maximally twisted Wilson LQCD
Roberto Frezzotti, Giancarlo Rossi
We discuss how the peculiar properties of maximally twisted Wilson fermions can be exploited to set up a consistent LQCD computational scheme in which the CP-conserving matrix elem…
D-branes in a Big Bang/Big Crunch Universe: Misner Space
Yasuaki Hikida, Rashmi R. Nayak, Kamal L. Panigrahi
We study D-branes in a two-dimensional Lorentzian orbifold R^{1,1}/Γwith a discrete boost Γ. This space is known as Misner or Milne space, and includes big crunch/big bang singular…
Anti-de Sitter D-brane dynamics
J. Kluson, Kamal L. Panigrahi
We study the anti-de Sitter D-brane dynamics in Hamiltonian formulation. By exploiting the existence of certain conserved charges, we solve the equation of motion for a D1-brane in…

Andrea M. Lionetto
We show some phenomenological implications for the dark matter problem of a class of models with deflected anomaly mediated supersymmetry breaking in the context of the MSSM. This…
Non-thermal Cosmic Backgrounds from Blazars: the contribution to the CMB, X-ray and gamma-ray Backgrounds
P. Giommi, S. Colafrancesco, E. Cavazzuti +2
We present a new assessment of the contribution of Blazars to the extragalactic background radiation across the e.m. spectrum. Our calculations rely on deep Blazar radio counts tha…
Space-like and time-like pion electromagnetic form factor and Fock state components within the Light-Front dynamics
J. P. B. C. de Melo, T. Frederico, E. Pace +1
The simultaneous investigation of the pion electromagnetic form factor in the space- and time-like regions within a light-front model allows one to address the issue of non-valence…
