In particle physics, the Pontecorvo–Maki–Nakagawa–Sakata matrix (PMNS matrix), Maki–Nakagawa–Sakata matrix (MNS matrix), lepton mixing matrix, or neutrino mixing matrix is a unitarymixing matrix which contains information on the mismatch of quantum states of neutrinos when they propagate freely and when they take part in weak interactions. It is a model of neutrino oscillation. This matrix was introduced in 1962 by , , and Shoichi Sakata,to explain the neutrino oscillations predicted by Bruno Pontecorvo.

C’est une matrice unitaire (hormis dans le mécanisme de see-saw) servant de matrice de passage entre deux bases orthonormées de l'espace des états des neutrinos : d'une part la base des états propres (eigenstate) de saveur et d'autre part celle des états propres d'énergie ou de masse (eigenmass) des neutrinos. Dans les réactions faisant intervenir les neutrinos, ceux-ci sont produits dans un état de saveur bien défini (neutrino-électron, par exemple). Comme cet état se décompose comme une superposition d'états propres du Hamiltonien, de masses différentes, il n'est (fr) Nel modello standard della fisica delle particelle la matrice Maki-Nakagawa-Sakata (matrice MNS) è una matrice unitaria che contiene informazioni sull'accoppiamento non idoneo tra stati quantici deboli di sapore e i neutrini. È l'equivalente della matrice CKM nel settore dei quark. Questa matrice è stata introdotta nel 1962 dai fisici giapponesi , e , per spiegare l'oscillazione del neutrino predetta da Bruno Pontecorvo (per questo è anche chiamata matrice PMNS).

М. Понтекорво, в 1957 году впервые рассмотревшего смешивание нейтрино, и , и С. Сакаты, сделавших это в 1962 году. (ru)
