“…Among these, superluminal behavior and flavor oscillations are the most studied and discussed issues. Furthermore, superluminality and flavor oscillation behavior are observed in very similar experiments [39][40][41][42], which suggests that they are related to the same physical phenomenon [43][44][45]. This explains why other authors have attempted to investigate these phenomena by considering them to be intimately connected with each other [43][44][45].…”

An evanescent wave is a non-propagating wave with an imaginary wave vector. In this study, we prove that these are solutions of the tachyon-like Klein-Gordon equation, and that in the tunneling of ultrarelativistic spin-1/2 particles they describe superluminal states arising from interactions between a particle and barrier. These states decay as a particle emerges from the opposite side of a potential barrier, conserving the same initial energy but not necessarily the same mass. The obtained theory is applied to the neutrino, to explain flavor oscillations during free flight and determine the conditions that maximize the probability of their occurrence.

“…The ∼2 σ tension between these ∆m 2 21 measurement could be tested by Hyper-K. The tension is derived from the asymmetry of the solar neutrino flux during day and night (day-night asymmetry), which ws indicated by Super-K [13]. The asymmetry would arises from the terrestrial matter effect.With Hyper-K, the day-night asymmetry effect can be measured precisely with the large statistics.…”

Hyper-Kamiokande (Hyper-K) is a proposed next generation underground large water Cherenkov detector. We propose to build two cylindrical water tanks in our experimental period, filled with ultra pure water and surrounded with newly developed photo sensors. In total, it will provide the fiducial volume of 0.19-0.37 Mt. The energies, positions, directions and types of charged particles produced by neutrino interactions are detected using its Cherenkov light in water. Our detector will be located at deep underground to reduce the cosmic muon flux and its spallation products, which is a dominant background for the analysis of the low energy astrophysical neutrinos. With the fruitful physics research programs planned for the accelerator neutrinos, atomospheric neutrinos and nucleon decay, Hyper-K will play a considerable role in the next neutrino physics frontier, even in the neutrino astrophysics. It will provide remarkable information for both of particle physics and astrophysics with its large statistics of astrophysical neutrino measurements, i.e., solar neutrino, supernova burst neutrinos and supernova relic neutrino. Here, we will discuss about physics potential of Hyper-K at neutrino astrophysics and expected performance of the detector.
