[en] The OPERA experiment was designed to search for ν_μ → ν_τ oscillations in appearance mode, i.e. by detecting the τ leptons produced in charge current ν_τ interactions. The experiment took data from 2008 to 2012 in the CNGS beam. Five observed ν_τ candidates together with low background 0.25 ± 0.05 allow to assess the discovery of ν_μ → ν_τ oscillations in appearance mode with significance larger than 5σ.

[en] A very preliminary analysis of quark fragmentation functions Dsub(u)sup(h+-) (z) is done with approximately 3500 neutrino induced reaction νN → μ^-h^+-x in the bubble chamber Gargamelle

[en] A search for inclusive nu/sub μ/ or anti nu/sub μ/ oscillations has been performed in the Fermilab narrow band neutrino beam using two detectors running simultaneously at two distances from the neutrino source. The data show no evidence for either nu/sub μ/ or anti nu/sub μ/ oscillations and rule out oscillations of nu/sub μ/ or anti nu/sub μ/ into any other single type of /nu for 15 < Δm² < 1000 eV²/c⁴ and sin²(2theta) > 0.02 - 0.40

[en] Recent theoretical results on charged particle interaction with planarly oriented thin bent crystals are reviewed, with the emphasis on dynamics in the continuous potential. Influence of boundary conditions on the volume-reflected beam profile is discussed. Basic properties of coherent bremsstrahlung in a bent crystal are highlighted.

[en] The existence of a bound state of five quarks with c-bar content is still controversial. In this paper we focus on weakly decaying charmed pentaquarks and show how they can be searched for in high energy anti-neutrino interactions. By analyzing 2262 charged-current interactions with a muon of positive charge in the CHORUS detector, we performed a search for Θ_c⁰ production. Based on the null observation, the limit of Θ_c⁰ production is found as a function of different Θ_c⁰ lifetimes. The tightest bound is σ_Θc⁰/σ_ν-bar<0.039 at 90% C.L. for Θ_c⁰ lifetime equal to 0.5τ_D⁰. We outline also the excellent potentiality of such a search at a neutrino factory with an emulsion detector

[en] Three possible settings are considered for the question of two interacting charged conducting balls: (1) both balls are kept at constant and equal potentials; (2) one ball is charged and isolated, the other is kept at a constant potential with the same sign as the first, and (3) both balls are like charged and isolated. It is shown that fundamentally different problems generally arise here: whereas in the first case the balls always repel, in the second and third cases fairly wide ranges of radius and charge ratios can always be found in which the balls attract each other at close distances. These ranges are identified in the paper. The results are presented of experiments that demonstrate both the repulsion and attraction of like-charged balls. Theory and experiment show satisfactory agreement, both qualitatively and quantitatively. (methodological notes)

[en] In this report we shall present the results of the charged current group's effort, although as we shall see, it is not clear that the apparatus needed for the detection of either of these interactions is very different. (orig.)

[en] This thesis presents results of the MINOS long baseline neutrino oscillation experiment. Charged Current interactions of ν_μ from the NuMI beamline have been recorded in both the Near and Far Detectors between May 2005 and February 2006, corresponding to 1.27 x 10²⁰ protons being delivered to the NuMI target. Several techniques for improving the sensitivity of an oscillation measurement are discussed and their impact assessed. 378 events are observed in the Far Detector during this period, compared to a prediction of 459 ± 31 events are observed in the Far Detector during this period, compared to a prediction of 459 ± 31 events when the observed Near Detector spectrum is extrapolated to the Far Detector over the 735 km baseline with no oscillations. In addition to this deficit of observed events, there is also evidence for spectral distortion in the Far Detector. A maximum likelihood analysis is used to determine the best fit point and allowed regions in Δm²₂₃ and sin²2θ₂₃ parameter space. The best fit values for Δm²₂₃ and sin²2θ₂₃ are found to be 2.55^+0.39_-0.24 x 10^-3 eV² and > 0.87 (68% CL) respectively

[en] NOνA is a long-baseline neutrino experiment using an off-axis neutrino beam produced by the NuMI neutrino beam at Fermilab. The NOνA experiment will study neutrino ν_μ → ν_e oscillations. A short term goal for the NOνA experiment is to develop a good understanding of the response of the detector. These studies are being carried out with the full Near Detector installed on the surface (NDOS) at Fermilab. This detector is currently running and will acquire neutrino data for a year. Using beam muon neutrino data, quasi-elastic charged-current interactions will be studied. Status of the NDOS running and early data will be shown.
