First Observation of an Exotic Reggeon

G. D. Alexeev, M.G. Alexeev, C. Alice, A. Amoroso et autres

We present new \compass high-statistics measurements of the peripheral production of $ηπ^-$ and $η^\prime π^-$ pairs in the reactions $π^- p \to η^{(\prime)}π^- p$. For the first time, we perform an unbinned analysis of the high-mass region of the $ηπ^-$ and $η^\primeπ^-$ …

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 …

Sensitivity of the Hyper-Kamiokande experiment to neutrino oscillation parameters using accelerator neutrinos

K. Abe, M. T. Afif, R. Ahl Laamara, H. Aihara et autres

Abstract This paper presents the expected sensitivity to the neutrino oscillation parameters of the Hyper-Kamiokande long-baseline program. The Hyper-Kamiokande experiment, currently under construction in Japan, will measure the oscillations of accelerator-produced neutrinos with thousands of selected events per sample: this corresponds to …

Addendum to multiplicities of charged pions, kaons and unidentified charged hadrons on an isoscalar target measured by COMPASS Collaboration

G. D. Alexeev, M.G. Alexeev, C. Alice, A. Amoroso et autres

The COMPASS Collaboration has recently published an article “Multiplicities of positive and negative pions, kaons, and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target”, Phys. Rev. D 112 (2025) 012002. In contrast to earlier COMPASS publications on similar …

Dihadron Transverse-Spin Asymmetries in Muon-Deuteron Deep-Inelastic Scattering

G. D. Alexeev, M.G. Alexeev, C. Alice, A. Amoroso et autres

In 2022, the COMPASS collaboration performed semi-inclusive measurements of deep-inelastic muon-scattering on a transversely polarised deuteron (6LiD) target. From these data, transverse-spin-dependent dihadron asymmetries are extracted using pairs of oppositely charged hadrons. These asymmetries are directly sensitive to the quark transversity distributions …

Data Release for the "First differential measurement of the single positive pion production cross section in neutrino neutral-current scattering"

Abe K, S. Abe, R. Akutsu, H. Alarakia-Charles et autres

Since its first observation in the 1970s, neutrino-induced neutral-current single positive pion production (NC1$π^+$) has remained an elusive and poorly understood interaction channel. This process is a significant background in neutrino oscillation experiments and studying it further is critical for the physics …
