B-physics anomalies: a guide to combined explanations [PDF]

open access: yesJournal of High Energy Physics, 2017
AbstractMotivated by additional experimental hints of Lepton Flavour Universality violation inBdecays, both in charged- and in neutral-current processes, we analyse the ingredients necessary to provide a combined description of these phenomena. By means of an Effective Field Theory (EFT) approach, based on the hypothesis of New Physics coupled ...

Comment on anomaly matching in N=1 supersymmetric QCD [PDF]

open access: yes, 1998
An attempt is made at a systematic approach to anomaly matching problem in non-Abelian electric-magnetic duality in N=1 supersymmetric QCD. A strategy we employ is somewhat analogous to anomaly analyses in grand unified models where the anomaly ...

Long-Lived Particles Anomaly Detection with Parametrized Quantum Circuits

open access: yesParticles, 2023
We investigate the possibility to apply quantum machine learning techniques for data analysis, with particular regard to an interesting use-case in high-energy physics.

Testing Lorentz invariance violations in the tritium beta-decay anomaly [PDF]

open access: yes, 2000
We consider a Lorentz non-invariant dispersion relation for the neutrino, which would produce unexpected effects with neutrinos of few eV, exactly where the tritium beta-decay anomaly is found.

New Physics Agnostic Selections For New Physics Searches [PDF]

open access: yesEPJ Web of Conferences, 2020
We discuss a model-independent strategy for boosting new physics searches with the help of an unsupervised anomaly detection algorithm. Prior to a search, each input event is preprocessed by the algorithm - a variational autoencoder (VAE).

Lieb-Schultz-Mattis, Luttinger, and 't Hooft - anomaly matching in lattice systems [PDF]

open access: yesSciPost Physics, 2022
We analyze lattice Hamiltonian systems whose global symmetries have ’t Hooft anomalies. As is common in the study of anomalies, they are probed by coupling the system to classical background gauge fields.

The Dark Machines Anomaly Score Challenge: Benchmark Data and Model Independent Event Classification for the Large Hadron Collider

open access: yesSciPost Physics, 2022
We describe the outcome of a data challenge conducted as part of the Dark Machines Initiative and the Les Houches 2019 workshop on Physics at TeV colliders.

Experimental signature of the parity anomaly in a semi-magnetic topological insulator [PDF]

open access: yesNature Physics, 2021
A three-dimensional (3D) topological insulator features a 2D surface state consisting of a single linearly dispersive Dirac cone1–3. Under broken time-reversal symmetry, the single Dirac cone is predicted to cause half-integer quantization of Hall ...

Muon g-2: Review of Theory and Experiment [PDF]

open access: yes, 2007
A review of the experimental and theoretical determinations of the anomalous magnetic moment of the muon is given. The anomaly is defined by a=(g-2)/2, where the Land\'e g-factor is the proportionality constant that relates the spin to the magnetic ...

Impact of polarization observables and Bc→τν on new physics explanations of the b→cτν anomaly [PDF]

open access: yesPhysical Review D, 2018
The combined analysis of the BABAR, Belle, and LHCb data on B→Dτν, B→D∗τν and Bc→J/Ψτν decay observables shows evidence of physics beyond the Standard Model (SM). In this article, we study all the one- and two-dimensional scenarios which can be generated
