A MEASUREMENT OF THE NEUTRAL CURRENT NEUTRINO-NUCLEON ELASTIC CROSS SECTION AT MINIBOONE
The neutral current neutrino-nucleon elastic interaction ν N [arrow right] ν N is a fundamental process of the weak interaction ideally suited for characterizing the structure of the nucleon neutral weak current. This process comprises ∼18% of neutrino events in the neutrino oscillation experiment, …

Forward jet production in neutral current deep inelastic scattering with ZEUS at HERA
… of 318 GeV. Forward jets as a certain class of neutral current events are selected to probe different parton evolution models. The measured cross sections depending on Bjoerken-x and transverse energy are based on the luminosity of 76 pb-1. For the running period of 1998-2000 the calorimetric …

Measurement of the Neutral Current Cross Section and Search for Contact Interactions with the H1 Experiment at HERA
A measurement of the inclusive neutral current cross section for deep inelastic positron-proton scattering and a subsequent search for electron-quark contact interactions are presented. The analysis is based on data taken in 1999 and 2000 at a centre-of-mass energy of sqrt(s)=319 GeV with the H1 …

Single pi-zero production in neutrino interactions
… Laboratory Alternating Gradient Synchrotron. The neutral current reactions, vn -> vnpio and vp + vprr , and the charged current reaction, vn -> u-ppi0 ,were investigated. The neutrino detector was made up of optical spark chambers and liquid o and solid scintillation counters. The pi0 is detected …

Neutron backgrounds in the Ricochet experiment
… is an ideal detection method because it is a neutral current process. All active neutrino flavors will therefore be detected uniformly (no non-active, or sterile neutrinos will be detected because they do not couple to the Z boson). By varying the distance between the detector and the neutrino …

P-resonant control for the neutral point of three phase inverter
In this project, a Proportional resonant (PR) current controller is proposed to maintain a balanced neutral point for a three-phase four wire inverter, which can be used in microgrid applications. The neutral-point circuit consists of a conventional neutral leg and a split DC link. The neutral …

Identifying muons for neutrino oscillation and cross section experiments
… only fundamental fermions which are electrically neutral; their mass is orders of magnitude smaller than the lightest charged lepton, the electron; and their solely weak interactions make them an excellent probe of the weak nuclear force. However, one of the most interesting aspects of neutrinos …

Probing Lepton Flavour Universality With $\bz \to \kstarz \taup \taum$
<p>Neutral current $\bquark \to \squark ll$ processes have long been known to be precise probes of physics beyond the Standard Model. A pattern of anomalies seen in $\bquark \to \squark \mup \mun$ and in $\bquark \to \cquark \tau \nu$ data has hinted at the violation of lepton flavour universality. …
