Robust implications on Dark Matter from the first FERMI sky gamma map
Michele Papucci, Alessandro Strumia
We derive robust model-independent bounds on DM annihilations and decays from the first year of FERMI gamma-ray observations of the whole sky. These bounds only have a mild depende…
Renormalization Of High-Energy Lorentz Violating QED
Damiano Anselmi, Martina Taiuti
We study a QED extension that is unitary, CPT invariant and super-renormalizable, but violates Lorentz symmetry at high energies, and contains higher-dimension operators (LVQED). D…
Higgs mediated Double Flavor Violating top decays in Effective Theories
A. Fernandez, C. Pagliarone, F. Ramirez-Zavaleta +1
The possibility of detecting double flavor violating top quark transitions at future colliders is explored in a model-independent manner using the effective Lagrangian approach thr…
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…
Composite Vectors at the Large Hadron Collider
Riccardo Barbieri, Antonio E. Carcamo, Gennaro Corcella +2
An unspecified strong dynamics may give rise to composite vectors sufficiently light that their interactions, among themselves or with the electroweak gauge bosons, be approximatel…
Instanton effects on Wilson-loop correlators: a new comparison with numerical results from the lattice
M. Giordano, E. Meggiolaro
Instanton effects on the Euclidean correlation function of two Wilson loops at an angle , relevant to soft high-energy dipole-dipole scattering, are calculated in the Instanton…
Euclidean-Minkowskian duality of Wilson-loop correlation functions
M. Giordano, E. Meggiolaro
We discuss the analyticity properties of the Wilson--loop correlation functions relevant to the problem of soft high-energy scattering, directly at the level of the functional inte…
Angular-ordered parton showers with medium-modified splitting functions
Nestor Armesto, Gennaro Corcella, Leticia Cunqueiro +1
Modified Altarelli-Parisi splitting functions were recenty proposed to model multi-parton radiation in a dense medium and describe jet quenching, one of most striking features of h…
Radiation Problem in Transplanckian Scattering
Paolo Lodone, Slava Rychkov
We investigate hard radiation emission in small-angle transplanckian scattering. We show how to reduce this problem to a quantum field theory computation in a classical background…
Minimal Matter at the Large Hadron Collider
Eugenio Del Nobile, Roberto Franceschini, Duccio Pappadopulo +1
We classify all possible new U(1) x SU(2) x SU(3) multiplets that can couple to pairs of SM particles. Assuming that production of such new particles is dominated by their gauge in…
The likelihood for supernova neutrino analyses
A. Ianni, G. Pagliaroli, A. Strumia +3
We derive the event-by-event likelihood that allows to extract the complete information contained in the energy, time and direction of supernova neutrinos, and specify it in the ca…
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…
A Phenomenological Study of Bottom Quark Fragmentation in Top Quark Decay
Gennaro Corcella, Federico Mescia
Top-quark physics is one of the main fields of investigation at the Tevatron accelerator and, ultimately, at the LHC. We perform a phenomenological analysis of ttbar events at hadr…
Standard Model Without Elementary Scalars And High Energy Lorentz Violation
Damiano Anselmi
If Lorentz symmetry is violated at high energies, interactions that are usually non-renormalizable can become renormalizable by weighted power counting. Recently, a CPT invariant,…
Non-Abelian Global Vortices
Minoru Eto, Eiji Nakano, Muneto Nitta
We study topologically stable non-Abelian global vortices in the U(N) linear sigma model. The profile functions of the solutions are numerically obtained. We investigate the behavi…
Minimal Dark Matter: model and results
Marco Cirelli, Alessandro Strumia
We recap the main features of Minimal Dark Matter (MDM) and assess its status in the light of the recent experimental data. The theory selects an electroweak 5-plet with hypercharg…
A nonperturbative foundation of the Euclidean-Minkowskian duality of Wilson-loop correlation functions
M. Giordano, E. Meggiolaro
In this letter we discuss the analyticity properties of the Wilson-loop correlation functions relevant to the problem of soft high-energy scattering, directly at the level of the f…
SUSY without the Little Hierarchy
B. Bellazzini, C. Csaki, A. Delgado +1
We propose a simple gauge extension of the minimal supersymmetric standard model (MSSM), where the fine tuning in the Higgs mass parameters is highly reduced. The Higgs boson is in…
