Quark mixing from Δ(6N2) family symmetry
No full textAbstractWe consider a direct approach to quark mixing based on the discrete family symmetry Δ(6N2) in which the Cabibbo angle is determined by a residual Z2×Z2 subgroup to be |Vus|=0.222521, for N being a multiple of 7. We propose a particular model in which unequal smaller quark mixing angles and CP phases may occur without breaking the residual Z2×Z2 symmetry. We perform a numerical analysis of the model for N=14, where small Z2×Z2 breaking effects of order 3% are allowed by model, allowing perfect agreement within the uncertainties of the experimentally determined best fit quark mixing values
Letter from Morio Tanimoto to Mr. and Mrs. Okine, January [1], [1948?] [in Japanese]
No full textA New Year's letter from Morio Tanimoto to Seiichi and Tomeyo Okine. Morio Tanimoto is a father of their daughter-in-law, Ayame Okine. He expresses his appreciation for the Christmas gift from the Okines, and is glad to see a photograph of Ayame's daughter, Jeanne Okine.The Okine Collection contains materials collected by Seiichi and Tomeyo Okine who were Issei flower growers in Whittier, California. It includes correspondence, photographs, financial documents, and a photo album. A large portion of the collection consists of family correspondence with Seiichi and Tomeyo Okine, including letters from their Nisei children, Masao and Makoto Okine, both soldiers overseas during World War II, to their Issei parents incarcerated in the Rohwer incarceration camp in McGehee, Arkansas. The correspondence also includes letters from their relatives and friends who are former incarcerees in the camps during the war and have “resettled” in Chicago, Illinois as well as letters from the Okines’ family members in Hiroshima, Japan during the Allied occupation of Japan. In addition, the collection includes a family photo album compiled by Dorothy Ai Aoki, a Nisei daughter to the Okines

Neutrino mass and mixing: from theory to experiment
No full textThe origin of fermion mass hierarchies and mixings is one of the unresolved and most difficult problems in high-energy physics. One possibility to address the flavour problems is by extending the standard model to include a family symmetry. In the recent years it has become very popular to use non-Abelian discrete flavour symmetries because of their power in the prediction of the large leptonic mixing angles relevant for neutrino oscillation experiments. Here we give an introduction to the flavour problem and to discrete groups that have been used to attempt a solution for it. We review the current status of models in light of the recent measurement of the reactor angle, and we consider different model-building directions taken. The use of the flavons or multi-Higgs scalars in model building is discussed as well as the direct versus indirect approaches. We also focus on the possibility of experimentally distinguishing flavour symmetry models by means of mixing sum rules and mass sum rules. In fact, we illustrate in this review the complete path from mathematics, via model building, to experiments, so that any reader interested in starting work in the field could use this text as a starting point in order to obtain a broad overview of the different subject areas
