Towards a muon collider
Varun Sharma, Riccardo Rattazzi, Xavier Buffat, Filippo Nardi, Niko Neufeld, Luca Bottura, Andrea Wulzer, Roberto Franceschini, Alfredo Glioti, Riccardo Torre, Siyu Chen, Lorenzo Ricci, Brian Quinn Henning, Marco Valente, Xiaoran Zhao, Xin Sun, Alexej Grudiev, Ennio Salvioni, Marco Calviani, Jian Tang, Jing Shu, Tao Han, Alessandro Valenti, Laura Buonincontri, Luca Giambastiani
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 ...
Springer2023What 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 ...
Springer2016Heavy 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 ...
Springer2014A 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 ...
Springer2013Higgs 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 ...
Amer Physical Soc2013Strong, 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 ...
