Searches for the lepton number violating ${K}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}{e}^{+}$ decay and flavor ${K}^{+}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}{e}^{+}$ ${\ensuremath{\pi}}^{0}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{\ensuremath{-}}{e}^{+}$ decays are reported using data collected by NA62 experiment at CERN in 2017--2018. No evidence these is found upper limits of branching ratios obtained...
ND280 is a near detector of the T2K experiment which located in J-PARC accelerator complex Japan. After decade fruitful data-taking, scheduled for upgrade. The time-of-flight (ToF) detector, described this article, one three new detectors that will be installed basket ND280. ToF has modular structure. Each module represents an array 20 plastic scintillator bars are stacked plane 2.4 x 2.2 m2 area. Six modules similar construction assembled cube, thus providing almost 4pi enclosure active...
T2K (Tokai-to-Kamioka) is a long-baseline neutrino experiment in Japan designed to study various parameters of oscillations. A near detector complex (ND280) located 280 m downstream the production target and measures beam before any oscillations occur. ND280's measurements are used predict number spectra neutrinos Super-Kamiokande at distance 295 km. The difference material between far (water) (scintillator, hydrocarbon) detectors leads main non-cancelling systematic uncertainty for...
The design, construction and testing of neutrino detector prototypes at CERN are ongoing activities. This document reports on the design solid state baby MIND TASD outlines requirements for a test beam to these, tentatively planned H8 beamline in North Area, which is equipped with large aperture magnet. current proposal submitted be considered light recently approved projects related activities SPS Area medium term 2015-2020.
The Baby MIND spectrometer is designed to measure the momentum and charge of muons from neutrino interactions in water hydrocarbon targets at J-PARC T59 (WAGASCI) experiment. WAGASCI experiment will ratio charged current interaction cross-sections on aiming reducing systematic errors oscillation analyses T2K. Construction detector within CERN Neutrino Platform framework was completed June 2017, where it underwent full commissioning characterization a particle beam line Proton Synchrotron...
The WAGASCI experiment being built at the J-PARC neutrino beam line will measure difference in cross sections from neutrinos interacting with a water and scintillator targets, order to constrain sections, essential for T2K oscillation measurements. A prototype Magnetised Iron Neutrino Detector (MIND), called Baby MIND, is constructed CERN act as magnetic spectrometer behind main target be able charge momentum of outgoing muon charged current interactions.
Baby MIND is a new downstream muon range detector for the WGASCI experiment. This article discusses distributed readout system and its timing requirements. The paper presents design of synchronization subsystem results test.
Baby MIND is a magnetized iron neutrino detector, with novel design features, and planned to serve as downstream muon spectrometer for the WAGASCI experiment on T2K beam line in Japan. One of main goals this reduce systematic uncertainties relevant CP-violation searches, by measuring contamination anti-neutrino mode T2K. currently being constructed at CERN, be operational Japan October 2017.

A plastic scintillator bar with dimensions 300 cm x 2.5 11 was exposed to a focused muon beam study its light yield and timing characteristics as function of position angle incidence. The scintillating read out at both ends by photomultiplier tubes whose pulse shapes were recorded waveform digitizers. Results obtained the WAVECATCHER SAMPIC digitizers are analyzed compared. discussion various factors affecting resolution is presented. Prospects for applications technology in large-scale...
The NA62 experiment at the CERN SPS recorded in 2007 a large sample of $K^+ \rightarrow \mu^+ \nu_\mu $ decays. A peak search missing mass spectrum this decay is performed. In absence observed signal, limits obtained on $\mathcal{B}(K^+ \nu_h )$ and mixing matrix element $|U_{\mu4}|$ are reported. upgraded started data taking 2015. About 5$\times 10^{11} K^+$ decays have been so far to measure branching ratio \pi^+ \nu\overline{\nu}$ decay. Preliminary results from analysis based about 5$\%$...
The decay $K^{+} \rightarrow \pi^{+}\nu\overline{\nu}$ has a very precisely predicted branching ratio ($\sim 8\times 10^{-11}$) and it is one of the best candidates to reveal indirect effects new physics. NA62 experiment at CERN SPS designed measure with decay-in-flight technique, novel for this channel. taken data firstly in 2016 aim reach SM sensitivity. It then collected 10 times more statistics 2017 similar amount expected from 2018 run. preliminary result on full set prospects future...
In this paper we present new results on upper limits for the search of Heavy Neutral Leptons (HNL) with data collected by NA48/2 (2003-2004), NA62-RK (2007) and NA62 (2015) CERN experiments. The different trigger configuration allow to both long short living heavy neutrinos in mass range below kaon mass. addition status K + → π v detector will be briefly presented.
