Weak nonleptonic decays of charm baryons emitting scalar mesons
We investigate the weak nonleptonic decays of charm baryons emitting scalar mesons employing the factorization scheme and predict their branching ratios.

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.

Generic lepton mass matrices and neutrino oscillations
Several intriguing aspects of neutrino oscillation phenomenology like the origin of small neutrino masses, the absolute neutrino mass scale, the neutrino mass hierarchy, i.e. normal or inverted and the nature of neutrinos, i.e. Dirac or Majorana, etc. have been addressed from a general perspective. We show how the fundamental considerations of unitary transformations, naturalness and seesaw mechanism suffices to determine the texture structure of fermion Yukawa couplings and discuss the significance of the effective mass in 0{\nu}{\beta}{\beta} decay for the texture structure of these couplings.
