CDMS stands for Constrained Dark Matter Singlet

Marco Farina, Duccio Pappadopulo, Alessandro Strumia

Motivated by the two candidate Dark Matter events observed by the CDMS experiment, we consider a Constrained Dark Matter Singlet (CDMS) model that, with no free parameters, predict…

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…

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…

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…

S-particles at their naturalness limits

Riccardo Barbieri, Duccio Pappadopulo

We draw attention on a particular configuration of supersymmetric particle masses, motivated by naturalness and flavour considerations. All its relevant phenomenological properties…

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…
