Fecha de publicación: | 1-may-2013 | Editor: | EDP Sciences | Citación: | EPL - Europhysics Letters (102): 41001 (2013) | Resumen: | Recent experiments show that the top-right corner element (U-e3) of the PMNS matrix is small but nonzero, and suggest further via unitarity that it is smaller than the bottom-left corner element (U-tau 1). Here, it is shown that if to the assumption of a universal rank-one mass matrix, long favoured by phenomenologists, one adds that this matrix rotates with scale, then it follows that A) by inputting the mass ratios m(c)/m(t), m(s)/m(b), m(mu)/m(tau), and m(2)/m(3), i) the corner elements are small but nonzero, ii) V-ub < V-td, U-e3 < U-tau 1, iii) estimates result for the ratios V-ub/V-td and U-e3/U-tau 1, and B) by inputting further the experimental values of V-us, V-tb and U-e2, U-mu 3, iv) estimates result for the values of the corner elements themselves. All the inequalities and estimates obtained are consistent with present data within expectation for the approximations made. | Versión del editor: | http://dx.doi.org/ 10.1209/0295-5075/102/41001 | URI: | http://hdl.handle.net/10261/108635 | DOI: | 10.1209/0295-5075/102/41001 | ISSN: | 0295-5075 |
