Quark mixing from muon collider neutrinos
David Marzocca, Francesco Montagno, Manuel Morales-Alvarado +1
A high energy muon collider naturally produces a collimated beam of neutrinos for a fixed-target experiment at a dedicated far-forward facility. The high intensity and energy of th…
Flavor physics at high-energy muon colliders
Alfredo Glioti, David Marzocca, Andrea Wulzer
Flavor-breaking interactions due to heavy new physics can be probed at a 10 TeV muon collider in the high-energy production of quarks and leptons. The high collision energy mitigat…
Quantifying EFT Uncertainties in LHC Searches
Spencer Chang, Markus A. Luty, Teng Ma +2
Effective Field Theory (EFT) is a general framework to parametrize the low-energy approximation to a UV model that is widely used in model-independent searches for new physics. The…
Why detect forward muons at a muon collider
Maximilian Ruhdorfer, Ennio Salvioni, Andrea Wulzer
We survey the opportunities offered by the detection of the forward muons that accompany the creation of neutral effective vector bosons at a muon collider, in different kinematic…
Low-virtuality splitting in the Standard Model
Filippo Nardi, Lorenzo Ricci, Andrea Wulzer
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 vir…
Boosting likelihood learning with event reweighting
Siyu Chen, Alfredo Glioti, Giuliano Panico +1
Extracting maximal information from experimental data requires access to the likelihood function, which however is never directly available for complex experiments like those perfo…
Goodness of fit by Neyman-Pearson testing
Gaia Grosso, Marco Letizia, Maurizio Pierini +1
The Neyman-Pearson strategy for hypothesis testing can be employed for goodness of fit if the alternative hypothesis is selected from data by exploring a rich parametrised family o…

We present a machine learning approach for model-independent new physics searches. The corresponding algorithm is powered by recent large-scale implementations of kernel methods, n…
The collider landscape: which collider for establishing the SM instability?
Roberto Franceschini, Alessandro Strumia, Andrea Wulzer
Capabilities of future colliders are usually discussed assuming specific hypothetical new physics. We consider the opposite possibility: that no new physics is accessible, and we w…
The physics case of a 3 TeV muon collider stage
Jorge De Blas, Dario Buttazzo, Rodolfo Capdevilla +131
In the path towards a muon collider with center of mass energy of 10 TeV or more, a stage at 3 TeV emerges as an appealing option. Reviewing the physics potential of such muon coll…
