New milestone reached in the study of electroweak symmetry breaking

Observed and predicted BDT distributions in the signal regions (left for the four-lepton channel and right for the two-lepton and two-neutrino channel). Credit: ATLAS Collaboration/CERN In the Standard Model of particle physics, elementary particles acquire their masses by interacting with the Higgs field. This process is governed by a delicate mechanism: electroweak symmetry breaking (EWSB). […]

Two-dimensional (2-D) nuclear magnetic resonance (NMR) spectroscopy with a microfluidic diamond quantum sensor

Microfluidic pre-polarization NMR setup. (A) Comparison of statistical and thermal polarization of protons in water as a function of detection volume. The room temperature water proton density is ρ = 6.7 × 1028 m−3. (B) Prepolarization concept. Analyte is prepolarized by flowing it through a permanent magnet (1.5-T Halbach array). It is subsequently shuttled to […]
