Goldstone equivalence and high energy electroweak physics

Andrea Wulzer, Luca Vecchi, Gabriel Francisco Cuomo

The transition between the broken and unbroken phases of massive gauge theories, namely the rearrangement of longitudinal and Goldstone degrees of freedom that occurs at high energy, is not manifestly smooth in the standard formalism. The lack of smoothnes ...

Learning from radiation at a very high energy lepton collider

Riccardo Rattazzi, Andrea Wulzer, Siyu Chen, Alfredo Glioti, Lorenzo Ricci

We study the potential of lepton collisions with about 10 TeV center of mass energy to probe Electroweak, Higgs and Top short-distance physics at the 100 TeV scale, pointing out the interplay with the long-distance (100 GeV) phenomenon of Electroweak radia ...

Learning new physics from a machine

Andrea Wulzer, Raffaele Tito D'Agnolo

We propose using neural networks to detect data departures from a given reference model, with no prior bias on the nature of the new physics responsible for the discrepancy. The virtues of neural networks as unbiased function approximants make them particu ...

Parametrized classifiers for optimal EFT sensitivity

Andrea Wulzer, Siyu Chen, Alfredo Glioti

We study unbinned multivariate analysis techniques, based on Statistical Learning, for indirect new physics searches at the LHC in the Effective Field Theory framework. We focus in particular on high-energy ZW production with fully leptonic decays, modeled ...

Massive pions, anomalies and baryons in holographic QCD

Andrea Wulzer

We consider a holographic model of QCD, obtained by a very simple modification of the original construction, which describes at the same time the pion mass, the QCD anomalies and the baryons as topological solitons. We study in detail its phenomenological ...

Boosting likelihood learning with event reweighting

Andrea Wulzer, Alfredo Glioti, Siyu Chen

Extracting maximal information from experimental data requires access to the likelihood function, which however is never directly available for complex experiments like those performed at high energy colliders. Theoretical predictions are obtained in this ...

A first top partner hunter's guide

Riccardo Rattazzi, Andrea Wulzer, Andrea De Simone

We provide a systematic effective lagrangian description of the phenomenology of the lightest top-partners in composite Higgs models. Our construction is based on symmetry, on selection rules and on plausible dynamical assumptions. The structure of the res ...

Stable skyrmions from extra dimensions

Andrea Wulzer

We show that skyrmions arising from compact five dimensional models have stable sizes. We numerically obtain the skyrmion configurations and calculate their size and energy. Although their size strongly depends on the magnitude of localized kinetic-terms, ...

A Strong Sector at the LHC: Top Partners in Same-Sign Dileptons

Andrea Wulzer, Jan Dalibor Mrazek

Heavy partners of the top quark are a common prediction of many models in which a new strongly-coupled sector is responsible for the breaking of the electroweak symmetry. In this paper, we investigate their experimental signature at the LHC, focusing on th ...

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 ...

Two paths towards precision at a very high energy lepton collider

Andrea Wulzer, Roberto Franceschini

We illustrate the potential of a very high energy lepton collider (from 10 to 30 TeV center of mass energy) to explore new physics indirectly in the vector boson fusion double Higgs production process and in direct diboson production at high energy. Double ...

AdS/QCD: the relevance of the geometry

Andrea Wulzer

We investigate the relevance of the metric and of the geometry in five-dimensional models of hadrons. Generically, the metric does not affect strongly the results and even flat space agrees reasonably well with the data. Nevertheless, we observe a preferen ...

Nucleon form factors from 5D skyrmions

Andrea Wulzer

Several aspects of hadron physics are well described by a simple 5D effective field theory, Baryons arise in this scenario as "large" (and therefore calculable) 5D skyrmions. We extend and reline the existing analysis of this 5D soliton, which is fairly no ...

Learning multivariate new physics

We discuss a method that employs a multilayer perceptron to detect deviations from a reference model in large multivariate datasets. Our data analysis strategy does not rely on any prior assumption on the nature of the deviation. It is designed to be sensi ...

Based on an explicit model, we propose and discuss the generic features of a possible implementation of the Twin Higgs program in the context of composite Higgs models. We find that the Twin Higgs quadratic divergence cancellation argument can be uplifted ...
