COUNTING STRANGE QUARKS FOR THE SKYRME MASSES
Adopting a view that the skyrmion and quarks may play complementary roles in the baryons, a simple mass term is shown to account for the discrepancy between Skyrme model and the experiment.

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.

Lower bound on neutrino mass and possible CP violation in neutrino oscillations
The phenomenology of the most general lepton mass matrices obtained through weak basis transformations has been discussed. Using a hierarchical parametrization of these mass matrices, the exact relations for lepton mixing angles have been obtained assuming normal neutrino mass hierarchy and natural structures of lepton mass matrices. The recent three neutrino oscillation data together with the condition of naturalness on Dirac lepton mass matrices provide a lower bound on the lightest neutrino mass of m{\nu}1 > 3 meV along with a non-vanishing Dirac CP violating phase.

Lepton textures and neutrino oscillations
A systematic analysis of the textures arising in lepton mass matrices have been carried out using unitary transformations and condition of naturalness for the Dirac and Majorana neutrino possibilities. It is observed that the recent three neutrino oscillation data together with the effective mass in neutrinoless double beta decay provide vital clues in predicting the general structures of these lepton mass matrices.
