PPPC 4 DM ID: A Poor Particle Physicist Cookbook for Dark Matter Indirect Detection

Marco Cirelli, Gennaro Corcella, Andi Hektor +6

We provide ingredients and recipes for computing signals of TeV-scale Dark Matter annihilations and decays in the Galaxy and beyond. For each DM channel, we present the energy spec…

On the QCD corrections to Delta F=2 FCNC in the Supersymmetric SM with hierarchical squark masses

Enrico Bertuzzo, Marco Farina, Paolo Lodone

In the context of the Supersymmetric Standard Model with hierarchical sfermion masses, we re-analyze the QCD corrections to Delta F=2 effective Hamiltonian properly including effec…

Minimal Flavour Violation with hierarchical squark masses

Riccardo Barbieri, Enrico Bertuzzo, Marco Farina +2

In a supersymmetric model with hierarchical squark masses we analyze a pattern of flavour symmetry breaking centered on the special role of the top Yukawa coupling and, by extensio…

Weak Corrections are Relevant for Dark Matter Indirect Detection

Paolo Ciafaloni, Denis Comelli, Antonio Riotto +3

The computation of the energy spectra of Standard Model particles originated from the annihilation/decay of dark matter particles is of primary importance in indirect searches of d…

Signals of single particle production at the earliest LHC

Riccardo Barbieri, Riccardo Torre

Based on simple phenomenological Lagrangians, fulfilling reasonable consistency conditions, we consider under which circumstances the production of a single particle might be an ea…

Heavy Flavours in DIS and Hadron Colliders: Working Group Summary

Katerina Lipka, Gennaro Corcella

The recent theory developments and latest experimental results on heavy-flavour production in Deep Inelastic Scattering and at hadron colliders are summarized. Models of heavy quar…

The problem of the initial conditions in flavoured leptogenesis and the tauon N_2-dominated scenario

Enrico Bertuzzo, Pasquale Di Bari, Luca Marzola

We discuss the conditions to realize a scenario of strong thermal leptogenesis, where the final asymmetry is fully independent of the initial conditions, when both heavy and light…

A "composite" scalar-vector system at the LHC

Antonio E. Cárcamo Hernández, Riccardo Torre

In the framework of a strong dynamics for Electro-Weak Symmetry Breaking (EWSB), both vector and scalar degrees of freedom have been studied in the literature within an effective L…

A Non Standard Supersymmetric Spectrum

Riccardo Barbieri, Enrico Bertuzzo, Marco Farina +2

Taking a bottom-up point of view and focussing on the lack of signals so far in the Higgs and in the flavour sectors, we argue in favour of giving consideration to supersymmetric e…

Naturalness bounds in extensions of the MSSM without a light Higgs boson

Paolo Lodone

Adopting a bottom-up point of view, we make a comparative study of the simplest extensions of the MSSM with extra tree level contributions to the lightest Higgs boson mass. We show…

Experimental Constraints on Heavy Fermions in Higgsless Models

Raffaele Tito D'Agnolo

Using an effective Lagrangian approach we analyze a generic Higgsless model with composite heavy fermions, transforming as SU(2)_{L+R} Doublets. Assuming that the Standard Model fe…

Signals of composite electroweak-neutral Dark Matter: LHC/Direct Detection interplay

Riccardo Barbieri, Slava Rychkov, Riccardo Torre

In a strong-coupling picture of ElectroWeak Symmetry Breaking, a composite electroweak-neutral state in the TeV mass range, carrying a global (quasi-)conserved charge, makes a plau…
