Test of lepton universality in beauty-quark decays [PDF]

open access: yesNature Physics, 2021
The standard model of particle physics currently provides our best description of fundamental particles and their interactions. The theory predicts that the different charged leptons, the electron, muon and tau, have identical electroweak interaction ...

A Toy Model of Universality: Reverse Engineering How Networks Learn Group Operations [PDF]

open access: yesInternational Conference on Machine Learning, 2023
Universality is a key hypothesis in mechanistic interpretability -- that different models learn similar features and circuits when trained on similar tasks.

Test of Lepton Universality in b→sℓ^{+}ℓ^{-} Decays. [PDF]

open access: yesPhysical Review Letters, 2022
The first simultaneous test of muon-electron universality using B^{+}→K^{+}ℓ^{+}ℓ^{-} and B^{0}→K^{*0}ℓ^{+}ℓ^{-} decays is performed, in two ranges of the dilepton invariant-mass squared, q^{2}.

Enhancing the Self-Universality for Transferable Targeted Attacks [PDF]

open access: yesComputer Vision and Pattern Recognition, 2022
In this paper, we propose a novel transfer-based targeted attack method that optimizes the adversarial perturbations without any extra training efforts for auxiliary networks on training data.

Kardar–Parisi–Zhang universality in a one-dimensional polariton condensate [PDF]

open access: yesNature, 2021
Revealing universal behaviours is a hallmark of statistical physics. Phenomena such as the stochastic growth of crystalline surfaces1 and of interfaces in bacterial colonies2, and spin transport in quantum magnets3–6 all belong to the same universality ...

Universality Laws for High-Dimensional Learning With Random Features [PDF]

open access: yesIEEE Transactions on Information Theory, 2020
We prove a universality theorem for learning with random features. Our result shows that, in terms of training and generalization errors, a random feature model with a nonlinear activation function is asymptotically equivalent to a surrogate linear ...

Universality of ultra-relativistic gravitational scattering [PDF]

open access: yesPhysics Letters B, 2020
We discuss the ultra-relativistic gravitational scattering of two massive particles at two-loop (3PM) level. We find that in this limit the real part of the eikonal, determining the deflection angle, is universal for gravitational theories in the two ...

Quantum test of the Universality of Free Fall using rubidium and potassium [PDF]

open access: yesEuropean Physical Journal D : Atomic, Molecular and Optical Physics, 2020
We report on an improved test of the Universality of Free Fall using a rubidium-potassium dual-species matter wave interferometer. We describe our apparatus and detail challenges and solutions relevant when operating a potassium interferometer, as well ...

Universality in the Classical Limit of Massless Gravitational Scattering. [PDF]

open access: yesPhysical Review Letters, 2020
We demonstrate the universality of the gravitational classical deflection angle of massless particles through O(G^{3}) by studying the high-energy limit of full two-loop four-graviton scattering amplitudes in pure Einstein gravity as well as N≥4 ...
