Quest for precision in hadronic cross sections at low energy: Monte Carlo tools vs. experimental data
S. Actis, A. Arbuzov, G. Balossini +53
We present the achievements of the last years of the experimental and theoretical groups working on hadronic cross section measurements at the low energy e+e- colliders in Beijing,…
Dark matter detection in the BMSSM
Nicolas Bernal, Andreas Goudelis
The addition of non-renormalizable terms involving the Higgs fields to the MSSM (BMSSM) ameliorates the little hierarchy problem of the MSSM. For neutralino dark matter, new region…
Running Effects on Lepton Mixing Angles in Flavour Models with Type I Seesaw
Yin Lin, Luca Merlo, Alessio Paris
We study renormalization group running effects on neutrino mixing patterns when a (type I) seesaw model is implemented by suitable flavour symmetries. We are particularly intereste…
Lepton Flavour Violation in a Supersymmetric Model with A4 Flavour Symmetry
Ferruccio Feruglio, Claudia Hagedorn, Yin Lin +1
We compute the branching ratios for mu-> e gamma, tau-> mu gamma and tau -> e gamma in a supersymmetric model invariant under the flavour symmetry group A4 X Z3 X U(1)_{FN}, in whi…
Non-universal minimal Z' models: present bounds and early LHC reach
Ennio Salvioni, Alessandro Strumia, Giovanni Villadoro +1
We consider non-universal 'minimal' Z' models, whose additional U(1) charge is a non-anomalous linear combination of the weak hypercharge Y, the baryon number B and the partial lep…
One-loop effective potential in M4 x T2 with and without 't Hooft flux
A. F. Faedo, D. Hernandez, S. Rigolin +1
We review the basic notions of compactification in the presence of a background flux. In extra-dimentional models with more than five dimensions, Scherk and Schwarz boundary condit…
Minimal Z' models: present bounds and early LHC reach
Ennio Salvioni, Giovanni Villadoro, Fabio Zwirner
We consider `minimal' Z' models, whose phenomenology is controlled by only three parameters beyond the Standard Model ones: the Z' mass and two effective coupling constants. They e…
Vacuum Alignment in SUSY A4 Models
Ferruccio Feruglio, Claudia Hagedorn, Luca Merlo
In this note we discuss the vacuum alignment in supersymmetric models with spontaneously broken flavour symmetries in the presence of soft supersymmetry (SUSY) breaking terms. We s…
Tri-Bimaximal Lepton Mixing and Leptogenesis
D. Aristizabal Sierra, F. Bazzocchi, I. de Medeiros Varzielas +2
In models with flavour symmetries added to the gauge group of the Standard Model the CP-violating asymmetry necessary for leptogenesis may be related with low-energy parameters. A…
Bimaximal neutrino mixing and weak complementarity with S4 discrete symmetry
Luca Merlo
The neutrino oscillation data are well explained by the tri-bimaximal pattern. Recently a paper appeared showing that also the bimaximal pattern could be a very good starting point…
SU(3) Flavour Symmetries and CP Violation
L. Calibbi, J. Jones-Perez, A. Masiero +3
In order to satisfy current FCNC and CP violation bounds, SUSY flavour structures cannot be generic. An interesting solution to these SUSY Flavour and CP Problems lies on the use o…
Flavor symmetries, leptogenesis and the absolute neutrino mass scale
E. Bertuzzo, P. Di Bari, F. Feruglio +1
We study the interplay between flavor symmetries and leptogenesis in the case when the scale of flavor symmetry breaking is higher than the scale at which lepton number is violated…
Antimatter signals of singlet scalar dark matter
A. Goudelis, Y. Mambrini, C. Yaguna
We consider the singlet scalar model of dark matter and study the expected antiproton and positron signals from dark matter annihilations. The regions of the viable parameter space…
Meson As a Probe of QCD Equation of State
Raghunath Sahoo, Tapan K. Nayak, Jan-e Alam +3
In this work, we extract the QCD Equation of State (EoS) using experimental results of the meson produced in nuclear collisions at AGS, SPS and RHIC energies. The data are conf…
The Probable Fate of the Standard Model
J. Ellis, J. R. Espinosa, G. F. Giudice +2
Extrapolating the Standard Model to high scales using the renormalisation group, three possibilities arise, depending on the mass of the Higgs boson: if the Higgs mass is large eno…
Short-Baseline Electron Neutrino Disappearance at a Neutrino Factory
Carlo Giunti, Marco Laveder, Walter Winter
We discuss short-baseline and very-short-baseline electron neutrino disappearance at a neutrino factory. We take into account geometric effects, such as from averaging over the dec…
Flavor Physics in the Quark Sector
M. Antonelli, D. M. Asner, D. Bauer +137
One of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor and measurements and theoretical interpretations of their res…
FCNC and CP Violation Observables in a SU(3)-flavoured MSSM
L. Calibbi, J. Jones-Perez, A. Masiero +3
A non-Abelian flavour symmetry in a minimal supersymmetric standard model can explain the flavour structures in the Yukawa couplings and simultaneously solve the SUSY flavour probl…
Tri-bimaximal Neutrino Mixing from A(4) and θ_{13} \sim θ_C
Yin Lin
It is a common believe that, if the Tri-bimaximal mixing (TBM) pattern is explained by vacuum alignment in an A(4) model, only a very small reactor angle, say θ_{13} \sim λ^2_C bei…
Revisiting Bimaximal Neutrino Mixing in a Model with S4 Discrete Symmetry
G. Altarelli, F. Feruglio, L. Merlo
In view of the fact that the data on neutrino mixing are still compatible with a situation where Bimaximal mixing is valid in first approximation and it is then corrected by terms…
A dynamical approach to link low energy phases with leptogenesis
Yin Lin
If lepton masses and mixings are explained by a flavour symmetry in seesaw model which leads to U_{e3}=0 at leading order, we find that, under reasonable assumptions, a future obse…
LFV and Dipole Moments in Models with A4 Flavour Symmetry
Luca Merlo
It is presented an analysis on lepton flavour violating transitions, leptonic magnetic dipole moments and electric dipole moments in a class of models characterized by the flavour…
Phenomenological Consequences of See-Saw in S4 Based Models
F. Bazzocchi, L. Merlo, S. Morisi
It was proposed a flavour model based on the symmetry group S4, managing to describe fermion masses and mixings. The Weinberg operator has been used in order to provide the smallne…
VSBL Electron Neutrino Disappearance
Carlo Giunti, Marco Laveder
We consider possible indications of Very-Short-BaseLine (VSBL) electron neutrino disappearance into sterile neutrinos in MiniBooNE neutrino data and Gallium radioactive source expe…
