FCC Physics Opportunities: Future Circular Collider Conceptual Design Report Volume 1

Pierluigi Bruzzone, Jan Steggemann, Elena Graverini, Jean-Michel Sallese, Thomas Rizzo, Luca Rossi, Rui Ning Wang, Fabio Avino, Xavier Buffat, Tatiana Pieloni

We review the physics opportunities of the Future Circular Collider, covering its e(+)e(-), pp, ep and heavy ion programmes. We describe the measurement capabilities of each FCC component, addressing the study of electroweak, Higgs and strong interactions, ...

One-loop effects from spin-1 resonances in Composite Higgs models

Roberto Contino

We compute the 1-loop correction to the electroweak observables from spin-1 resonances in SO(5)/SO(4) composite Higgs models. The strong dynamics is modeled with an effective description comprising the Nambu-Goldstone bosons and the lowest-lying spin-1 res ...

Effective field theory analysis of double Higgs boson production via gluon fusion

Roberto Contino, Minho Son

We perform a detailed study of double Higgs production via gluon fusion in the effective field theory (EFT) framework where effects from new physics (NP) are parametrized by local operators. Our analysis provides a perspective broader than the one followed ...

Strong Higgs interactions at a linear collider

Riccardo Rattazzi, Duccio Pappadopulo, Roberto Contino, Andrea Thamm

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 ...

eHDECAY: An implementation of the Higgs effective Lagrangian into HDECAY

Roberto Contino

We present eHDECAY, a modified version of the program HDECAY which includes the full list of leading bosonic operators of the Higgs effective Lagrangian with a linear or non-linear realization of the electroweak symmetry and implements two benchmark compos ...

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 ...

Strong double higgs production at the LHC

Riccardo Rattazzi, Roberto Contino

The hierarchy problem and the electroweak data, together, provide a plausible motivation for considering a light Higgs emerging as a pseudo-Goldstone boson from a strongly-coupled sector. In that scenario, the rates for Higgs production and decay di ff er ...
