Searching for Supernova Bursts in Super-Kamiokande IV

M. Mori, K. Abe, Y. Hayato, K. Hiraide et autres

Super-Kamiokande has been searching for neutrino bursts characteristic of core-collapse supernovae continuously, in real time, since the start of operations in 1996. The present work focuses on detecting more distant supernovae whose event rate may be too small to trigger in real …

JT-60SA edge plasma modeling under several resonant magnetic perturbation conditions

S. Enomoto, H. A. Tanaka, G. Kawamura, Matsunaga Go et autres

In fusion reactor, large transient heat load attributed to the edge localized mode (ELM) could damage the diverter plate. Therefore, it is needed to mitigate or supress the ELM amplitude and an application of the resonant magnetic perturbation (RMP) field is thought …

Gamma Ray Showers Observed at Ground Level in Coincidence With Downward Lightning Leaders

R. U. Abbasi, Abu‐Zayyad T., M. Allen, E. Barcikowski et autres

Bursts of gamma ray showers have been observed in coincidence with downward propagating negative leaders in lightning flashes by the Telescope Array Surface Detector (TASD). The TASD is a 700‐km2 cosmic ray observatory located in southwestern Utah, USA. In data collected between …

Atmospheric neutrino oscillation analysis with external constraints in Super-Kamiokande I-IV

K. Abe, C. Bronner, Y.Haga, Y. Hayato et autres

An analysis of atmospheric neutrino data from all four run periods of Super-Kamiokande optimized for sensitivity to the neutrino mass hierarchy is presented. Confidence intervals for Δm232, sin2θ23, sin2θ13 and δCP are presented for normal neutrino mass hierarchy and inverted neutrino mass …

Measurement of the single π⁰ production rate in neutral current neutrino interactions on water

First measurement of the νμ charged-current cross section on a water target without pions in the final state

K. Abe, J.Amey, C. Andreopoulos, L. Anthony et autres

This paper reports the first differential measurement of the charged-current interaction cross section of νμ on water with no pions in the final state. This flux-averaged measurement has been made using the T2K experiment’s off-axis near detector, and is reported in doubly …

Micron-size hydrogen cluster targets for over 100 MeV, high-repetitive, impurity-free proton beams via relativistic laser-plasma interactions

Yuuji Fukuda, S. Jinno, M. Kanasaki, H. A. Tanaka et autres

The laser-driven ion acceleration has been one of the most active areas of research during the last several years, because the accelerated ion beams have unique properties such as ultrashort duration, high brilliance, and low emittance. The recent advancements in laser-driven ion …
