Cosmology from Planck
Amedeo Balbi
I briefly review some of the main scientific outputs expected from the upcoming Planck mission. Planck will map the CMB sky with 5' resolution and K sensitivity, with minimal fo…
Electromagnetic form factors of the nucleon in spacelike and timelike regions
J. P. B. C. de Melo, T. Frederico, E. Pace +2
An approach for a unified description of the nucleon electromagnetic form factors in spacelike and timelike regions is presented. The main ingredients of our model are: a Mand…
On Cardy states in the (2,2,2,2) Gepner model
Gor Sarkissian
We study Cardy states in the (2,2,2,2) Gepner model from the algebraic and geometric sides. We present the full list of primaries of this model together with their characters. The…
Deflected Anomaly Mediation and Neutralino Dark Matter
Alessandro Cesarini, Francesco Fucito, Andrea Lionetto
We study the phenomenology of the neutralino dark matter in the so called deflected anomaly mediation scenario. This scheme is obtained from the minimal anomaly mediated scenario b…
QCD with light Wilson quarks on fine lattices (I): first experiences and physics results
L. Del Debbio, L. Giusti, M. Lüscher +2
Recent conceptual, algorithmic and technical advances allow numerical simulations of lattice QCD with Wilson quarks to be performed at significantly smaller quark masses than was p…
Instanton on toric singularities and black hole countings
Francesco Fucito, Jose F. Morales, Rubik Poghossian
We compute the instanton partition function for U(N) gauge theories living on toric varieties, mainly of type including or $O_{\PP_1}(-p)$ sur…
N=4 Superconformal Characters and Partition Functions
M. Bianchi, F. A. Dolan, P. J. Heslop +1
Character formulae for positive energy unitary representations of the N=4 superconformal group are obtained through use of reduced Verma modules and Weyl group symmetry. Expansions…
Pole Approximation for the pion eletromagnetic form factor within light-front dynamics
J. P. B. C. de Melo, J. S. Veiga, T. Frederico +2
We carefully investigate the reliability of the propagator Pole Approximation, i.e, the approximation of retaining only the propagator in the evaluation of the Mandelstam covariant…
Dalitz plot analysis of e+ e- --> pi0 pi0 gamma events at SQRT(s) ~ M(phi) with the KLOE detector
KLOE Collaboration
We have studied the Dalitz plot of the e+ e- --> pi0 pi0 gamma events collected at SQRT(s) ~ M(phi) with the KLOE detector. In the dipion invariant mass (Mpp) region below 700 MeV,…
Monte Carlo simulation of virtual Compton scattering below pion threshold
P. Janssens, L. Van Hoorebeke, H. Fonvieille +22
This paper describes the Monte Carlo simulation developed specifically for the VCS experiments below pion threshold that have been performed at MAMI and JLab. This simulation gener…
Non-perturbative renormalisation of left-left four-fermion operators with Neuberger fermions
P. Dimopoulos, L. Giusti, P. Hernandez +5
We outline a general strategy for the non-perturbative renormalisation of composite operators in discretisations based on Neuberger fermions, via a matching to results obtained wit…
On the all-order perturbative finiteness of the deformed N=4 SYM theory
G. C. Rossi, E. Sokatchev, Ya. S. Stanev
We prove that the chiral propagator of the deformed N=4 SYM theory can be made finite to all orders in perturbation theory for any complex value of the deformation parameter. For a…
New Two-loop Contributions to Hadronic EDMs in the MSSM
Junji Hisano, Minoru Nagai, Paride Paradisi
Flavor-changing terms with CP-violating phases in the quark sector may contribute to the hadronic electric dipole moments (EDMs). However, within the Standard Model (SM), the sourc…
Integrated Sachs-Wolfe effect from the cross correlation of WMAP3 year and the NRAO VLA sky survey data: New results and constraints on dark energy
Davide Pietrobon, Amedeo Balbi, Domenico Marinucci
We cross-correlate the new 3 year Wilkinson Microwave Anistropy Probe (WMAP) cosmic microwave background (CMB) data with the NRAO VLA Sky Survey (NVSS) radio galaxy data, and find…
Extraction of the Neutron Magnetic Form Factor from Quasi-Elastic 3He(pol)(e(pol),e') at Q^2 = 0.1 - 0.6 (GeV/c)^2
001 Collaboration
We have measured the spin-dependent transverse asymmetry, A_T', in quasi-elastic inclusive electron scattering from polarized 3He with high precision at Q^2 = 0.1 to 0.6 (GeV/c)^2.…
Hints of large tan(beta) in flavour physics
Gino Isidori, Paride Paradisi
Motivated by the first evidence of the B -> tau nu transition reported by Belle and by the precise DeltaM_{B_s} measurement by CDF, we analyse these and other low-energy observable…
Measurement of the DANE luminosity with the KLOE detector using large angle Bhabha scattering
KLOE Collaboration
We describe the method of measuring the integrated luminosity of the collider DANE, the Frascati factory. The measurement is done with the KLOE detector selecting l…
The science of PAMELA space mission
P. Picozza, A. Morselli
Many different mechanisms can contribute to antiprotons and positrons production, ranging from conventional reactions up to exotic processes like neutralino annihilation. The open…
Exploring the flavour structure of the MSSM with rare K decays
Gino Isidori, Federico Mescia, Paride Paradisi +2
We present an extensive analysis of rare K decays, in particular of the two neutrino modes K+->pi+ nu nu-bar and KL->pi0 nu nu-bar, in the Minimal Supersymmetric extension of the S…
Decay constants of P-wave heavy-light mesons from unquenched lattice QCD
UKQCD Collaboration, G. Herdoiza, C. McNeile +1
We review some decays that require knowledge of the decay constants of heavy-light mesons. We compute the decay constants of P-wave heavy-light mesons from unquenched latti…
