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. …

Suche nach Kontakt-Wechselwirkungen und Gravitoneffekten in der tief-inelastischen Streuung bei HERA
Neutral current events in deep inelastic scattering at HERA taken with the H1 detector are examined with respect to standard model expectations. The measured inclusive cross section ds/dQ2 for Q2>200 GeV2 in reactions e±p-->e±X is analysed in terms of contact interactions or graviton effects in …
