Analysis of an Antineutrino Detector
… We are building a 650 kg mobile, surface-level antineutrino detector, called CHANDLER. CHANDLER detects antineutrinos through inverse beta decay (IBD), using a highly segmented array of plastic scintillator segments to identify the positron through topology, and sheets of lithium-doped zinc …

Selecting electron antineutrino charged-current interactions at the T2K ND280
The contamination from ν ̄e in the T2K antineutrino beam is predicted to be approximately 1% and needs to be evaluated in order to constrain the systematic uncertainties in a T2K antineutrino oscillation measurement. In this thesis we present a ν ̄e charged-current selection with which we test the …

Precision Search for Muon Antineutrino Disappearance Oscillations Using a Dual Baseline Technique
A search for short baseline muon antineutrino disappearance with the SciBooNE and MiniBooNE experiments at Fermi National Accelerator Laboratory in Batavia, Illinois is presented. Short baseline muon antineutrino disappearance measurements help constrain sterile neutrino models. The two detectors …

Corrections to and Applications of the Antineutrino Spectrum Generated by Nuclear Reactors
In this work, the antineutrino spectrum as specifically generated by nuclear reactors is studied. The topics covered include corrections and higher-order effects in reactor antineutrino experiments, one of which is covered in Ref. [1] and another contributes to Ref. [2]. In addition, a practical …

Neutron Measurements and Reactor Antineutrino Search with the SNO+ Detector in the Water Phase
… on the reactor antineutrino flux for SNO+ is obtained using a maximum likelihood approach. The limit is about a factor of 9 higher than the expected signal in SNO+, which can be calculated using available reactor output power data.

Exotic V[over-bar][subscript e] -->V[over-bar][subscript slash-e] oscillations in Double Chooz
… a least-squares fit to the simulated electron antineutrino reactor spectrum1 . By comparing the expected spectra from the null hypothesis and the (3 + 1) oscillation hypothesis at the Double Chooz near detector L = 200 m, we expect a modest sterile neutrino discovery potential, limited by the ~ …

Searches for new physics at MiniBooNE : sterile neutrinos and mixing freedom
… interpretation of LSND at 98% C.L., the antineutrino search shows an excess of events which is in agreement with the two neutrino Vu -->Ve oscillation interpretation of LSND, and excludes the no oscillations hypothesis at 96% C.L. Even though the neutrino and antineutrino oscillation …

Measuring the charged pion and kaon contributions to the T2K neutrino beam in neutrino and antineutrino running modes using ν μ and ν ̄ μ CC inclusive selections in the ND280 detector
… on the magnetic horn current, a neutrino or antineutrino enhanced beam can be produced. It is important to understand the flux and flavour content of the beam, in order to maximise sensitivity of the experiment. The T2K experiment uses flux models constrained by external measurement from the …
