We propose and validate a method of antineutrino energy reconstruction for charged-current meson-less interactions on composite fully active targets containing hydrogen (such as hydrocarbon scintillator), which is largely free the poorly understood nuclear effects that usually distort bias attempts to measure neutrino energy.

We argue that the fixed target experiment PS191 operating on a proton beam of 19.2 GeV at CERN in eighties was sensitive to hypothetical light scalars produced by mesons and decaying charged particles. The dedicated searches for sterile neutrinos weak meson decays into final states with pairs particles: electrons muons. Two tracks from same point have been adopted as signal signature. Exploiting signature we use negative results place new limits coupled Standard Model (SM) particles via...
We calculate the signal rate of hypothetical heavy neutral leptons (HNL or sterile neutrinos) from kaon decays expected in framework SHiP experiment. The kaons are produced hadronic shower initiated beam-dump mode by 400 GeV protons CERN SPS. For a sufficiently light HNL (when kinematically allowed) we find to be noticeably richer source as compared D-meson adopted previous studies phenomenology at SHiP. In particular, is capable fully exploring central part allowed region mass and mixing...
The modeling of neutrino-nucleus interactions constitutes a challenging source systematic uncertainty for the extraction precise values neutrino oscillation parameters in long-baseline accelerator experiments. To improve such and minimize corresponding uncertainties, new generation detectors is being developed, which aim to measure complete final state particles resulting from interactions. In order fully benefit improved detector capabilities, simulations nuclear effects on final-state...
In order to extract neutrino oscillation parameters, precision long-baseline experiments rely on detailed models of interactions with nuclei. These constitute an important source systematic uncertainty, partially because detectors date have been blind final state neutrons. Three-dimensional projection scintillator trackers comprise components the near next generation experiments. Due good timing resolution and fine granularity, this technology is capable measuring neutron kinetic energy in...

We calculate the production of hypothetical millicharged particles (MCPs) sub-GeV masses by J-PARC proton beam in framework T2K and future T2HK neutrino oscillation experiments. Concentrating on region model parameter space, where an MCP can hit near detector twice, we adopt this background-free signature to estimate sensitivity experiments MCPs. find that a previously inaccessible direct searches charges 5$\times$$10^{-4}$-$10^{-2}$ $e$ for 0.1-0.5 GeV be probed.
