Cấu trúc hương vị lepton tối thiểu dẫn đến sự trộn lẫn không tối đa 2-3
Tóm tắt
Dữ liệu hiện tại ủng hộ sự trộn lẫn 2-3 lớn nhưng không tối đa trong miền lepton. Chúng tôi lập luận rằng giá trị này, liên quan đến sinθ_13 ≃ 0.15, là kết quả chung của các cấu trúc hương vị tối thiểu. Chúng tôi trình bày một số hiện thân khác nhau của tuyên bố này, dưới dạng ma trận khối lượng lepton phụ thuộc vào một số lượng nhỏ tham số, có thể được giải thích bằng các triệu chứng hương vị rời rạc. Chúng tôi cũng đề xuất một quy trình tổng quát để nghiên cứu mối tương quan giữa θ_23, quy mô tuyệt đối và thứ tự của các khối lượng neutrino, cũng như các pha vi phạm CP lepton.
