Weak hadronic and radiative decays of non-strange charmed baryons in SU(3) for the u, d and c quark sector
Some unsatisfactory features of the GIM model are noted and SU(3) u, d, c symmetry is employed to discuss weak hadronic and radiative decays. Comparing the NN pi weak vertex in the u, d, s and u, d, c quark sectors, we estimate the decay rates and asymmetry parameters of some charmed baryons.

Preliminary estimate of branching ratios of weak hadronic decays of bottom baryons emitting charmless scalar mesons
We give the first estimate of charmless scalar-meson emitting weak hadronic decays of $\varLambda _{b}^{0}$, $\varXi _{b}^{0}$ and $\varXi _{b}^{ -}$ bottom baryons employing the pole model and consequently predict their branching ratios.

Texture specific mass matrices with Dirac neutrinos and their implications
Considering Dirac neutrinos and Fritzsch-like texture six zero and five zero mass matrices, detailed predictions for cases pertaining to normal/inverted hierarchy as well as degenerate scenario of neutrino masses have been carried out. All the cases considered here pertaining to inverted hierarchy and degenerate scenario of neutrino masses are ruled out by the existing data. For the normal hierarchy cases, the lower limit of m{sub {nu}{sub 1}} and of s{sub 13} as well as the range of Dirac-like CP violating phase {delta}{sub l} would have implications for the texture specific cases considered here.

Implications of precision measurements on texture specific fermion mass matrices
Implications of texture specific mass matrices have been investigated for both quarks and neutrinos. Interestingly, for the case of quarks Fritzsch-like texture 4 zero mass matrices have been found to be compatible with the present precisely known sin 2β as well as other precise CKM matrix elements. In the case of leptonic mass matrices, for both Majorana and Dirac neutrinos we find that for texture 4, 5, 6 zero mass matrices the inverted hierarchy and degenerate scenarios of neutrino masses are ruled out by the present data.
