Since they give at best only qualitative features of the neutrino mass, additional constraints are considered. Cosmology restricts the masses of stable neutrinos and lifetimes of the unstable ones.

All these features have to be considered when new evidence (e.g., the recent suggestion of 17 keV neutrino) are placed in the broader context.","PeriodicalId":316054,"journal":{"name":"Intersections between particle and nuclear physics","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115998507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
