A reconstruction method for anisotropic universes in unimodular -gravity
A. Costantini, E. Elizalde
An extension of unimodular Einsteinian gravity in the context of gravities is used to construct a class of anisotropic evolution scenarios. In unimodular GR the determinant…
(New) Physics at a multi-TeV Collider
Antonio Costantini
We present the results of the physics reach of a multi-TeV muon collider for popular models of physics beyond the Standard Model. We include also details about a model predicting t…
The Effective Vector Boson Approximation in High-Energy Muon Collisions
Richard Ruiz, Antonio Costantini, Fabio Maltoni +1
Due to the inclination for forward gauge radiation, lepton colliders beyond a few TeV are effectively electroweak (EW) boson colliders, suggesting the treatment of EW bosons as con…
Vector-like quarks decaying into singly and doubly charged bosons at LHC
Gennaro Corcella, Antonio Costantini, Margherita Ghezzi +3
We investigate the production of vector-like quarks with charge at the LHC and their subsequent decays into new singly or doubly charged bosons plus a heavy quark (top or bot…

We provide a detailed analysis of the decays of doubly-charged bilepton gauge bosons , as predicted in models based on a symmetry.…
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…

Antonio Costantini
We discuss the most relevant features of a BSM model with extra gauge symmetry, the so called 331 model. The gauge group is impling the presen…
Extra Quarks and Bileptons in BSM Physics in a Model
Claudio Coriano, Antonio Costantini
We describe some salient features of the (Frampton-Pisano-Pleitez) bilepton model, in which the constraints of anomaly cancelation require the number of generations to be t…

The discovery made at the Large Hadron Collider (LHC) has revealed that the spontaneous symmetry breaking mechanism is realised in a gauge theory such as the Standard Model (SM) by…
