Unique Mass Texture for Quarks and Leptons

Abstract

Texture specific quark mass matrices which are hermitian and hierarchical are examined in detail . In the case of texture 6 zeros matrices, out of sixteen possibilities examined by us, none is able to fit the low energy data (LED), for example, $V_{us}=0.2196\pm 0.0023$, $V_{cb}=0.0395\pm 0.0017$, $\frac{V_{ub}}{V_{cb}}=0.08\pm 0.02$, $V_{td}$ lies in the range $0.004-0.013$ (PDG). Similarly none of the 32 texture 5 zeros mass matrices considered is able to reproduce LED. In particular, the latest data from LEP regarding $|V_{ub}|/|V_{cb}|(=0.093\pm 0.016)$ rules out all of them. In the texture 4 zeros case, we find that there is a unique texture structure for $U$ and $D$ mass matrices which is able to fit the data.
