Test of lepton universality with B 0 → K *0 ℓ + ℓ − decays [PDF]

open access: yesJournal of High Energy Physics, 2017
A test of lepton universality, performed by measuring the ratio of the branching fractions of the B 0 → K *0 μ + μ − and B 0 → K *0 e + e − decays, $$ {R}_{K^{*0}} $$ , is presented.

Two Universality Classes for the Many-Body Localization Transition [PDF]

open access: yesPhysical Review Letters, 2017
We provide a systematic comparison of the many-body localization (MBL) transition in spin chains with nonrandom quasiperiodic versus random fields. We find evidence suggesting that these belong to two separate universality classes: the first dominated by

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 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 ...

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}.

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 ...

Perceptions of and barriers to ethical promotion of pharmaceuticals in Pakistan: perspectives of medical representatives and doctors

open access: yesBMC Medical Ethics, 2021
Background In Pakistan, drug promotion practices, ethical or unethical, have rarely been in the spotlight. We aimed to assess the perception and barriers of medical representatives (MRs) and doctors (MDs) regarding ethical promotion of pharmaceuticals in

Villain-Becoming and Body without Organs: A Deleuze-Guattarian Rhizoanalysis of Paul Auster’s Invisible

open access: yesCritical Literary Studies, 2021
The present paper seeks to argue that the opposing roles Paul Auster has devised for his protagonists in Invisible (2010) evolve around metamorphosic changes in their behaviors in terms of Deleuze and Guattari’s rhizome theory.

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 ...
