Strong Higgs interactions at a linear collider

Riccardo Rattazzi, Duccio Pappadopulo, Andrea Thamm, Roberto Contino

We study the impact of Higgs precision measurements at a high-energy and high-luminosity linear electron positron collider, such as CLIC or the ILC, on the parameter space of a strongly interacting Higgs boson. Some combination of anomalous couplings are a ...

Heavy vector triplets: bridging theory and data

Andrea Wulzer, Duccio Pappadopulo, Andrea Thamm, Riccardo Torre

We introduce a model-independent strategy to study narrow resonances which we apply to a heavy vector triplet of the Standard Model (SM) group for illustration. The method is based on a simplified phenomenological Lagrangian which reproduces a large class ...

A minimally tuned composite Higgs model from an extra dimension

Duccio Pappadopulo, Andrea Thamm, Riccardo Torre

We construct and study the 5D realization of a composite Higgs model with minimal tuning. The Higgs is a (pseudo-)Goldstone boson from the spontaneous breaking of a global SO(5) symmetry to an SO(4) subgroup. The peculiarity of our construction lies in the ...

A naturally light dilaton

Riccardo Rattazzi, Duccio Pappadopulo, Paolo Lodone, Lorenzo Vitale

Goldstone's theorem does not apply straightforwardly to the case of spontaneously broken scale invariance. We elucidate under what conditions a light scalar degree of freedom, identifiable with the dilaton, can naturally arise. Our construction can be cons ...

On Partial Compositeness and the CP asymmetry in charm decays

Riccardo Rattazzi, Duccio Pappadopulo, Paolo Lodone, Boaz Keren Zur, Luca Vecchi

Recently, the LHCb and CDF Collaborations reported the measure of an unexpectedly large direct CP asymmetry in D meson decays. In this paper we ask if new physics associated with Partial Compositeness could plausibly explain this result. We find that Compo ...

Model Building and Phenomenology on the Eve of the LHC Revolution

Duccio Pappadopulo

The discovery of a new bosonic resonance, whose interactions are consistent with those of the Standard Model Higgs boson, have been reported by the ATLAS and CMS collaborations. In this thesis we describe the theoretical reasons to consider the Standard Mo ...

Operator product expansion convergence in conformal field theory

Riccardo Rattazzi, Johnny Espin Pais, Duccio Pappadopulo

We clarify questions related to the convergence of the operator product expansion and conformal block decomposition in unitary conformal field theories (for any number of spacetime dimensions). In particular, we explain why these expansions are convergent ...

Strong, weak and flavor scalar triplets for the CDF Wjj anomaly

Duccio Pappadopulo, Riccardo Torre

A model describing the 4.1 sigma Wjj anomaly observed by the CDF experiment at the Tevatron collider is introduced. It features new scalar particles which are charged both under the SU(3)(C) and the SU(2)(L) gauge groups and which couple to pairs of quarks ...

T-parity, its problems and their solution

Alessandro Vichi, Duccio Pappadopulo

We point out a basic difficulty in the construction of little-Higgs models with T-parity which is overlooked by large part of the present literature. Almost all models proposed so far fail to achieve their goal: they either suffer from sizable electroweak ...

On the effect of resonances in composite Higgs phenomenology

Riccardo Rattazzi, Duccio Pappadopulo, Roberto Contino

We consider a generic composite Higgs model based on the coset SO(5)= SO(4) and study its phenomenology beyond the leading low-energy effective lagrangian approximation. Our basic goal is to introduce in a controllable and simple way the lowest-lying, poss ...

Can CoGeNT and DAMA modulations be due to Dark Matter?

Duccio Pappadopulo

We explore the dark matter interpretation of the anomalies claimed by the DAMA and COGENT experiments, in conjunction with the various null direct-detection experiments. An independent analysis of the COGENT data is employed and several experimental and as ...

Implications of XENON 100 and LHC results for Dark Matter models

Duccio Pappadopulo

We perform a fit to the recent XENON 100 data and study its implications for Dark Matter scenarios. We find that Inelastic Dark Matter is disfavored as an explanation to the DAMA/LIBRA annual modulation signal. Concerning the scalar singlet DM model, we fi ...

Lopsided gauge mediation

Riccardo Rattazzi, Roberto Franceschini, Duccio Pappadopulo, Andrea De Simone

It has been recently pointed out that the unavoidable tuning among supersymmetric parameters required to raise the Higgs boson mass beyond its experimental limit opens up new avenues for dealing with the so called mu-B-mu problem of gauge mediation. In fac ...

Minimal matter at the large hadron collider

Roberto Franceschini, Duccio Pappadopulo

We classify all possible new U(1)(Y) circle times SU(2)(L) circle times SU(3)(c) multiplets that can couple to pairs of SM particles. Assuming that production of such new particles is dominated by their gauge interactions we study their signals at LHC, fin ...

CDMS stands for Constrained Dark Matter Singlet

Duccio Pappadopulo

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, predicts the DM mass and the DM direct cross section to be in the range weakly favo ...

A non standard supersymmetric spectrum

Enrico Bertuzzo, Duccio Pappadopulo, Paolo Lodone

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 extensions of the Standard Model where the lightest Higgs boson has a mass be ...

S-particles at their naturalness limits

Duccio Pappadopulo

We draw attention on a particular configuration of supersymmetric particle masses, motivated by naturalness and flavour considerations. All its relevant phenomenological properties for the LHC are described in terms of a few physical parameters, irrespecti ...
