“…One can see that they will cover most of the allowed regions for ∆m 2 41 10 eV 2 and not too small sin 2 2ϑ ee . Figure 6(b) shows the sensitivities of the CeSOX [102] and BEST [103] source experiments, of IsoDAR@KamLAND [107] and C-ADS [108], and of the KATRIN [109]) electron neutrino mass experiment 9 . The source experiments will cover the large-sin 2 2ϑ ee parts of the allowed regions, the IsoDAR@KamLAND and C-ADS experiments can cover almost all the allowed regions, except the large-∆m 2 41 part and the small-sin 2 2ϑ ee -small-∆m 2 41 parts, and KATRIN will cover the large-∆m 2 41 part.…”

We present the results of an updated fit of short-baseline neutrino oscillation data in the framework of 3+1 active-sterile neutrino mixing. We first consider ν e andν e disappearance in the light of the Gallium and reactor anomalies. We discuss the implications of the recent measurement of the reactorν e spectrum in the NEOS experiment, which shifts the allowed regions of the parameter space towards smaller values of |U e4 | 2 . The β-decay constraints of the Mainz and Troitsk experiments allow us to limit the oscillation length between about 2 cm and 7 m at 3σ for neutrinos with an energy of 1 MeV. The corresponding oscillations can be discovered in a model-independent way in ongoing reactor and source experiments by measuring ν e andν e disappearance as a function of distance. We then consider the global fit of the data on short-baselinetransitions in the light of the LSND anomaly, taking into account the constraints from ν µ disappearance experiments, including the recent data of the MINOS and IceCube experiments. The combination of the NEOS constraints on |U e4 | 2 and the MINOS and IceCube constraints on |U µ4 | 2 lead to an unacceptable appearance-disappearance tension which becomes tolerable only in a pragmatic fit which neglects the MiniBooNE low-energy anomaly.

The effective amplitude of short-baselineν e oscillations is limited by 0.00048 sin 2 2ϑ eµ 0.0020 at 3σ. The restrictions of the allowed regions of the mixing parameters with respect to our previous global fits are mainly due to the NEOS constraints. We present a comparison of the allowed regions of the mixing parameters with the sensitivities of ongoing experiments, which show that it is likely that these experiments will determine in a definitive way if the reactor, Gallium and LSND anomalies are due to active-sterile neutrino oscillations or not.

The Compact Material Irradiation Facility (CMIF) in China is a current project that will provide a compact deuteron-beryllium neutron source. The target of this facility will be an intense and compact Isotope Decay-At-Rest (IsoDAR) neutrino source. In this paper, we propose a neutrino experiment using CMIF as the neutrino source and calculate its sensitivity to sterile neutrinos. With a 50 MeV, 10 mA deuteron beam impinging upon a thin beryllium target of a thickness 2 g/cm 2 , the electron antineutrino production rate can be up to 2.0 × 10 19 per day. When paired with an 80 ton liquid scintillator detector to study short baseline electron antineutrino disappearance, the inverse beta decay (IBD) event rate is large enough to investigate the parameter ranges of interest for neutrino anomalies. Our sensitivity analysis shows that a short baseline experiment at this platform will provide a very competitive sterile neutrino search, especially in the high-∆m 2 region (∆m 2 > 10 eV 2 ).

“…In addition, it is possible to further perform particle identification based on the ratio of Cherenkov light yield to scintillation light yield. Both features are also useful for neutrinoless double beta decay experiments [8,9,10], neutrino CP phase measurements [11,12], proton decay searches [6] and the study of geoneutrinos [13].…”

Slow liquid scintillator Cherenkov detectors have been proposed as part of several future neutrino experiments because they can provide both directionality and energy measurements. This feature is expected to enhance the sensitivities for MeV-scale neutrino physics, including solar physics, the search for supernova relic neutrino, and the study of geo-sciences. In this study, the characteristics of a slow liquid scintillator were investigated, along with the light yields and decay time constants for various combinations of linear alkylbenzene (LAB), 2,5diphenyloxazole (PPO), and 1,4-bis (2-methylstyryl)-benzene (bis-MSB). The results of our study indicated that LAB with 0.07 g/L of PPO and 13 mg/L of bis-MSB was the best candidate for an effective separation between Cherenkov and scintillation lights with a reasonably high light yield.
