Search for proton decay into a single charged antilepton and a massless invisible particle using the full pure water data set of Super-Kamiokande

Kamiokande Collaboration, Y. L. Liu, K Terada, K. Abe et autres

A search for proton decay via $p\rightarrow l^{+}+X$, where $l^{+}$ is a positively charged lepton and $X$ is an invisible, massless, neutral particle, was performed using a 401~kton$\cdot$years exposure representing the entire pure water phase of Super-Kamiokande. No significant indication of a …

First double-differential measurement of pionless charged-current muon neutrino interactions using kinematic imbalance observables on carbon and oxygen with the T2K experiment

K. Abe, S. Abe, H. Adhikary, R. Akutsu et autres

We report the first measurement of muon-neutrino charged-current cross section as a function of kinematic imbalance (KI) observables on oxygen with no pions and at least one proton in the final state, using the T2K ND280 detector. The cross section is extracted …

Signal selection and model-independent extraction of pionless charged-current muon neutrino cross section using double-differential kinematic imbalance observables on carbon and oxygen with the T2K experiment

K. Abe, S. Abe, H. Adhikary, R. Akutsu et autres

We present the first joint measurement of muon neutrino CC$0πNp$ interactions on carbon and oxygen targets, in two double-differential kinematic imbalance (KI) observable spaces, $δp_{T}$-$δα_{T}$ and $p_{N}$-$\cosθ_μ$. The measurement employs the ND280 detector of the T2K experiment and includes a detailed description …

Constraining Neutrino Interaction Uncertainties for Neutrino Oscillation Measurements at the T2K Experiment

K. Abe, S. Abe, H. Adhikary, R. Akutsu et autres

In the context of neutrino oscillation measurements from the T2K experiment, the off-axis near detector ND280 plays a crucial role in constraining the incoming neutrino flux and neutrino-nucleus interaction cross sections. The result is a robust control over systematic uncertainties in the …

TeV-scale neutrino cross-section measurement using upward through-going muons in Super-Kamiokande

N Bhuiyan, K. Abe, Y. Asaoka, M. Harada et autres

Neutrinos provide a unique probe of both particle physics and the high-energy universe, traversing astronomical distances with minimal interaction. Their charged-current scattering cross section encodes fundamental information about weak interactions and nucleon structure across a vast energy range, yet measurements at TeV …

Search for proton decay via $p \to e^{+}π^{0}π^{0}$ and $p \to μ^{+}π^{0}π^{0}$ in 0.401 megaton-years exposure of Super-Kamiokande I-V

Kamiokande Collaboration, K. Abe, S. Abe, Y. Asaoka et autres

We searched for proton decay via $p \to e^{+}π^{0}π^{0}$ and $p \to μ^{+}π^{0}π^{0}$ in 0.401 megaton-years of data collected in all pure water detector phases of Super-Kamiokande (SK) I-V. A theoretical study predicts proton decay rates without assuming a particular grand unified …

Development of Faster and More Accurate Supernova Localization at Super-Kamiokande

K. Abe, Y. Asaoka, Masayuki Harada, Y. Hayato et autres

The next nearby core-collapse supernova (SN) promises to yield a treasure of scientific information through multi-messenger astronomy. Early observations of the shock breakout (SBO) emissions are especially critical to understand the SN explosive mechanism as well as the properties of the progenitor …

Measurement of the branching ratio of ¹⁶N, ¹⁵C, ¹²B, and ¹³B isotopes through the nuclear muon capture reaction in the Super-Kamiokande detector

Y. Maekawa, K. Abe, S. Abe, Y. Asaoka et autres

The Super-Kamiokande detector has measured solar neutrinos for more than 25 years. The sensitivity for solar neutrino measurement is limited by the uncertainties of energy scale and background modeling. Decays of unstable isotopes with relatively long half-lives through nuclear muon capture, such …
