Towards the precise description of Composite Higgs models at colliders
Diogo Buarque Franzosi
We present a framework to study the interactions among Nambu-Goldstone bosons (NGB), pseudo-NGB (pNGBs) and gauge bosons in Composite Higgs (CH) models at high energies, including…

Tulika Bose, Antonio Boveia, Caterina Doglioni +318
This is the Snowmass2021 Energy Frontier (EF) Beyond the Standard Model (BSM) report. It combines the EF topical group reports of EF08 (Model-specific explorations), EF09 (More gen…
TF08 Snowmass Report: BSM Model Building
Patrick J. Fox, Graham D. Kribs, Hitoshi Murayama +53
We summarize the state of Beyond the Standard Model (BSM) model building in particle physics for Snowmass 2021, focusing mainly on several whitepaper contributions to BSM model bui…
Modelling vector-like quarks in partial compositeness framework
Avik Banerjee, Diogo Buarque Franzosi, Gabriele Ferretti
Composite Higgs models, together with partial compositeness, predict the existence of new scalars and vector-like quarks (partners) at and above the TeV scale. Generically, the pre…
Phenomenological aspects of composite Higgs scenarios: exotic scalars and vector-like quarks
Avik Banerjee, Diogo Buarque Franzosi, Giacomo Cacciapaglia +8
Composite Higgs models usually contain additional pseudo Nambu Goldstone bosons and vector-like quarks. We discuss various aspects related to their LHC phenomenology and provide su…
Electroweak signatures of gauge-mediated supersymmetry breaking in multiple hidden sectors
Diogo Buarque Franzosi, Gabriele Ferretti, Ellen Riefel +1
This paper discusses electroweak collider signatures of the NMSSM with multiple-sector gauge mediation. We focus on the production of neutralinos and charginos which cascade decay…
Vector Boson Scattering Processes: Status and Prospects
Diogo Buarque Franzosi, Michele Gallinaro, Richard Ruiz +26
Insight into the electroweak (EW) and Higgs sectors can be achieved through measurements of vector boson scattering (VBS) processes. The scattering of EW bosons are rare processes…
Beyond the Standard Model in Vector Boson Scattering Signatures
Michele Gallinaro, Kenneth Long, Jürgen Reuter +19
The high-energy scattering of massive electroweak bosons, known as vector boson scattering (VBS), is a sensitive probe of new physics. VBS signatures will be thoroughly and systema…
Pseudoscalar pair production via off-shell Higgs in composite Higgs models
Diogo Buarque Franzosi, Gabriele Ferretti, Li Huang +1
We propose a new type of search for a pseudoscalar particle pair produced via an off-shell Higgs, . The search is motivated by a composite Higgs model in which…

Julien Baglio, Alessandro Ballestrero, Riccardo Bellan +48
This document summarises the talks and discussions happened during the VBSCan Mid-Term Scientific Meeting workshop. The VBSCan COST action is dedicated to the coordinated study of…
Automated Predictions from Polarized Matrix Elements
Diogo Buarque Franzosi, Olivier Mattelaer, Richard Ruiz +1
The anticipated experimental resolution and data cache of the High Luminosity Large Hadron Collider will enable precision investigations of polarization in multiboson processes. Th…
Top-quark Partial Compositeness beyond the effective field theory paradigm
Diogo Buarque Franzosi, Alberto Tonero
In theories of Partial Compositeness the top quark is a mixture of a composite and an elementary state, and as a consequence its interactions with gauge bosons are expected to devi…

We explore the phenomenology of models containing one Vector-Like Quark (VLQ), , which can decay into the Standard Model (SM) top quark, , and a new spin-0 neutral boson, $S…

Anomalous dimensions of potential top-partners
Diogo Buarque Franzosi, Gabriele Ferretti
We discuss anomalous dimensions of top-partner candidates in theories of Partial Compositeness. First, we revisit, confirm and extend the computation by DeGrand and Shamir of anoma…
