Ultralight dark matter detection with trapped-ion interferometry

Leonardo Badurina, Diego Blas, John Ellis +1

We explore how recent advances in the manipulation of single-ion wave packets open new avenues for detecting weak magnetic fields sourced by ultralight dark matter. A trapped ion i…

Stable perturbative predictions for isolated photon production with a jet pair at large $m_{j_{1} j_{2}}$

Jeppe R. Andersen, Andreas Maier, Malina Rosca +1

We present the first calculation of the high-energy corrections to the process of isolated photon production in association with two jets. These corrections both stabilise the pert…

On electroweak metastability and Higgs inflation

Isabella Masina, Mariano Quiros

For the central values of the relevant experimental inputs, that is the strong coupling constant and the top quark and Higgs masses, the effective Higgs potential displays two mini…

Isospin breaking corrections in $2 π$ production in tau decays and $e^{+} e^{-}$ annihilation: consequences for the muon $g - 2$ and CVC tests

Gabriel López Castro, Alejandro Miranda, Pablo Roig

We revisit the isospin-breaking corrections relating the $e^{+} e^{-}$ hadronic cross-section and the tau decay spectral function, focusing on the di-pion channel, that gives the domina…

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…

The interplay of transverse degrees of freedom and axial-vector mesons with short-distance constraints in g-2

Pere Masjuan, Pablo Roig, Pablo Sanchez-Puertas

We revisit well-known short-distance constraints relating the hadronic light-by light Green's function to the $⟨ V V A ⟩$ one, that have been a subject of debate over the…

Symmetries in $B \to D^{*} ℓ ν$ angular observables

Marcel Algueró, Sébastien Descotes-Genon, Joaquim Matias +1

We apply the formalism of amplitude symmetries to the angular distribution of the decays $B \to D^{*} ℓ ν$ for $ℓ = e, μ, τ$ . We show that the angular observables used to describe…

Likelihood-free inference of experimental Neutrino Oscillations using Neural Spline Flows

Sebastian Pina-Otey, Federico Sánchez, Vicens Gaitan +1

In machine learning, likelihood-free inference refers to the task of performing an analysis driven by data instead of an analytical expression. We discuss the application of Neural…
