Towards a muon collider

Riccardo Rattazzi, Varun Sharma, Siyu Chen, Xavier Buffat, Brian Quinn Henning, Filippo Nardi, Niko Neufeld, Luca Bottura, Andrea Wulzer, Roberto Franceschini

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 ...

What is the gamma gamma resonance at 750 GeV?

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

Heavy vector triplets: bridging theory and data

Andrea Wulzer, Duccio Pappadopulo, Riccardo Torre, Andrea Thamm

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 ...

A minimally tuned composite Higgs model from an extra dimension

Duccio Pappadopulo, Riccardo Torre, Andrea Thamm

We construct and study the 5D realization of a composite Higgs model with minimal tuning. The Higgs is a (pseudo-)Goldstone boson from the spontaneous breaking of a global SO(5) symmetry to an SO(4) subgroup. The peculiarity of our construction lies in the ...

Higgs couplings in composite models

Francesco Riva, Riccardo Torre, Ennio Salvioni

We study Higgs couplings in the composite Higgs model based on the coset SO(5)/SO(4). We show that the couplings to gluons and photons are insensitive to the elementary-composite mixings and thus not affected by light fermionic resonances. Moreover, at lea ...

Strong, weak and flavor scalar triplets for the CDF Wjj anomaly

Duccio Pappadopulo, Riccardo Torre

A model describing the 4.1 sigma Wjj anomaly observed by the CDF experiment at the Tevatron collider is introduced. It features new scalar particles which are charged both under the SU(3)(C) and the SU(2)(L) gauge groups and which couple to pairs of quarks ...
