A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by ...

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 ...

What is the gamma gamma resonance at 750 GeV?

Francesco Riva, Riccardo Rattazzi, Michele Redi, Roberto Franceschini, Riccardo Torre

Run 2 LHC data show hints of a new resonance in the diphoton distribution at an invariant mass of 750 GeV. We analyse the data in terms of a new boson, extracting information on its properties and exploring theoretical interpretations. Scenarios covered in ...

Probing the scattering of equivalent electroweak bosons

Riccardo Rattazzi, Andrea Wulzer, Pascal Borel, Roberto Franceschini

We analyze the kinematic conditions under which the scattering of equivalent massive spin-1 vector bosons factorizes out of the complete process. In practice, we derive the conditions for the validity of the effective W approximation, proposed long ago but ...

Simplified models for LHC new physics searches

Roberto Franceschini, Yang Bai, Jing Shu, Tao Han, Yue Zhao, Tao Liu

This document proposes a collection of simplified models relevant to the design of new-physics searches at the Large Hadron Collider (LHC) and the characterization of their results. Both ATLAS and CMS have already presented some results in terms of simplif ...

Solving the mu problem with a heavy Higgs boson

Roberto Franceschini

We discuss the generation of the mu-term in a class of supersymmetric models characterized by a low energy effective superpotential containing a term lambda SH1H2 with a large coupling lambda similar to 2. These models generically predict a lightest Higgs ...

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 ...
