Detectors and flux instrumentation for future neutrino facilities
T. Abe, H. Aihara, C. Andreopoulos +66
This report summarises the conclusions from the detector group of the International Scoping Study of a future Neutrino Factory and Super-Beam neutrino facility. The baseline detect…
Role of Higher Multipole Excitations in the Electromagnetic Dissociation of One Neutron Halo Nuclei
R. Chatterjee, L. Fortunato, A. Vitturi
We investigate the role of higher multipole excitations in the electromagnetic dissociation of one-neutron halo nuclei within two different theoretical models -- a finite range dis…
Enlarging mSUGRA parameter space by decreasing pre-BBN Hubble rate in Scalar-Tensor Cosmologies
R. Catena, N. Fornengo, A. Masiero +2
We determine under what conditions Scalar Tensor cosmologies predict an expansion rate which is reduced as compared to the standard General Relativity case. We show that ST theorie…
Symmetry, shape, and order
Antonio Trovato, Trinh X. Hoang, Jayanth R. Banavar +1
Packing problems have been of great interest in many diverse contexts for many centuries. The optimal packing of identical objects has been often invoked to understand the nature o…
Structural motifs of biomolecules
Jayanth R. Banavar, Trinh X. Hoang, John H. Maddocks +4
Biomolecular structures are assemblies of emergent anisotropic building modules such as uniaxial helices or biaxial strands. We provide an approach to understanding a marginally co…
First Flavor-Tagged Determination of Bounds on Mixing-Induced CP Violation in Bs -> J/psi phi Decays
CDF Collaboration, T. Aaltonen
This Letter describes the first determination of bounds on the CP-violation parameter 2*beta_s using Bs decays in which the flavor of the bottom meson at production is identified.…
Strains and Jets in Black Hole Fields
D. Bini, F. de Felice, A. Geralico
We study the behaviour of an initially spherical bunch of particles emitted along trajectories parallel to the symmetry axis of a Kerr black hole. We show that, under suitable cond…
Fermion Mass Hierarchies and Flavour Mixing from a Minimal Discrete Symmetry
Ferruccio Feruglio, Yin Lin
We construct a simple model of fermion masses based on a spontaneously broken S3 X Z3 flavour group. At the leading order, in the neutrino sector S3 is broken down to a ν_μ-ν_τpari…
Analytical Approach to Subhaloes Population in Dark Matter Haloes
Carlo Giocoli, Lidia Pieri, Giuseppe Tormen
In the standard model of cosmic structure formation, dark matter haloes form by gravitational instability. The process is hierarchical: smaller systems collapse earlier, and later…
Halos of Unified Dark Matter Scalar Field
Daniele Bertacca, Nicola Bartolo, Sabino Matarrese
We investigate the static and spherically symmetric solutions of Einstein's equations for a scalar field with non-canonical kinetic term, assumed to provide both the dark matter an…
On the Physical Significance of Infra-red Corrections to Inflationary Observables
N. Bartolo, S. Matarrese, M. Pietroni +2
Inflationary observables, like the power spectrum, computed at one- and higher-order loop level seem to be plagued by large infra-red corrections. In this short note, we point out…
Measurement of Lifetime and Decay-Width Difference in B0s -> J/psi phi Decays
CDF collaboration, T. Aaltonen
We measure the mean lifetime, tau=2/(Gamma_L+Gamma_H), and the width difference, DeltaGamma=Gamma_L-Gamma_H, of the light and heavy mass eigenstates of the B0s meson, B0sL and B0sH…
Model-Independent and Quasi-Model-Independent Search for New Physics at CDF
CDF Collaboration
Data collected in Run II of the Fermilab Tevatron are searched for indications of new electroweak scale physics. Rather than focusing on particular new physics scenarios, CDF data…
Gauged Supergravities from Twisted Doubled Tori and Non-Geometric String Backgrounds
Gianguido Dall'Agata, Nikolaos Prezas, Henning Samtleben +1
We propose a universal geometric formulation of gauged supergravity in terms of a twisted doubled torus. We focus on string theory (M-theory) reductions with generalized Scherk-Sch…
Fast Estimator of Primordial Non-Gaussianity from Temperature and Polarization Anisotropies in the Cosmic Microwave Background II: Partial Sky Coverage and Inhomogeneous Noise
Amit P. S. Yadav, Eiichiro Komatsu, Benjamin D. Wandelt +3
In our recent paper (Yadav et al. 2007) we described a fast cubic (bispectrum) estimator of the amplitude of primordial non-Gaussianity of local type, f_{NL}, from a combined analy…
On general flux backgrounds with localized sources
Giovanni Villadoro, Fabio Zwirner
We derive new consistency conditions for string compactifications with generic fluxes (RR, NSNS, geometrical) and localized sources (D-branes, NS-branes, KK-monopoles). The constra…
Possibly Large Corrections to the Inflationary Observables
N. Bartolo, A. Riotto
We point out that the theoretical predictions for the inflationary observables may be generically altered by the presence of fields which are heavier than the Hubble rate during in…
Black Holes as Dark Matter Annihilation Boosters
Mattia Fornasa, Gianfranco Bertone
We review the consequences of the growth and evolution of Black Holes on the distribution of stars and Dark Matter (DM) around them. We focus in particular on Supermassive and Inte…
A Precise Measurement of the Muon Neutrino-Nucleon Inclusive Charged Current Cross-Section off an Isoscalar Target in the Energy Range 2.5 < E_ν< 40 GeV by NOMAD
NOMAD Collaboration, Q. K. Wu
We present a measurement of the muon neutrino-nucleon inclusive charged current cross-section, off an isoscalar target, in the neutrino energy range GeV. The…
Quantum Resonant Leptogenesis and Minimal Lepton Flavour Violation
Vincenzo Cirigliano, Andrea De Simone, Gino Isidori +2
It has been recently shown that the quantum Boltzmann equations may be relevant for the leptogenesis scenario. In particular, they lead to a time-dependent CP asymmetry which depen…
Low energy tracking and particles identification in the MUNU Time Projection Chamber at 1 bar. Possible application in low energy solar neutrino spectroscopy
Z. Daraktchieva, C. Amsler, M. Avenier +14
In this paper we present the results from the measurements made with the MUNU TPC at 1bar pressure of CF4 in the energy region below 1 MeV. Electron events down to 80 keV are succe…
Dark Matter Candidates: A Ten-Point Test
Marco Taoso, Gianfranco Bertone, Antonio Masiero
An extraordinarily rich zoo of non-baryonic Dark Matter candidates has been proposed over the last three decades. Here we present a 10-point test that a new particle has to pass, i…
Limits on nu_e and anti-nu_e disappearance from Gallium and reactor experiments
Mario A. Acero, Carlo Giunti, Marco Laveder
The deficit observed in the Gallium radioactive source experiments is interpreted as a possible indication of the disappearance of electron neutrinos. In the effective framework of…
The Effect of Primordial Non--Gaussianity on the Topology of Large-Scale Structure
Chiaki Hikage, Peter Coles, Margherita Grossi +4
We study the effect of primordial non-Gaussianity on the development of large-scale cosmic structure using high-resolution N-body simulations. In particular, we focus on the topolo…
