Geometry of soft scalars at one loop

We extend the soft theorems for scattering amplitudes of scalar effective field theories to one-loop order. Our analysis requires carefully accounting for the fact that the soft limit is not guaranteed to commute with evaluating IR-divergent loop integrals ...

Low-virtuality splitting in the Standard Model

Filippo Nardi

When the available collision energy is much above the mass of the particles involved, scattering amplitudes feature kinematic configurations that are enhanced by the much lower virtuality of some intermediate particle. Such configurations generally factori ...

Tetraquarks at large M and large N

Riccardo Rattazzi, Majid Ekhterachian, Filippo Nardi

We study tetraquarks in large N QCD with heavy quarks, in the domain where non-relativistic quantum mechanics offers an adequate approximation. Within the regime of validity of the Born-Oppenheimer approximation, we systematically study and explicitly cons ...

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 ...
