Charm changing weak hadronic decays of triplet (C=1) baryons emitting axial-vector mesons including factorizable and pole contributions
We investigate the weak nonleptonic decays of ${\ensuremath{\Lambda}}_{c}^{+}$, ${\ensuremath{\Xi}}_{c}^{+}$, and ${\ensuremath{\Xi}}_{c}^{0}$ into the octet baryons (${J}^{P}=1/{2}^{+}$) and axial-vector mesons (${J}^{P}={1}^{+}$) employing the factorization scheme for $W$-emission diagrams and the pole model for $W$-exchange contributions. Determining the baryon-baryon transition form factors in the nonrelativistic quark model and incorporating the constraints of heavy quark symmetry, we predict their branching ratios and asymmetry parameters.

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.

INVESTIGATING NON-FRITZSCH-LIKE TEXTURE SPECIFIC QUARK MASS MATRICES
A detailed investigation of all possible textures of Fritzsch-like and non-Fritzsch-like, 144 for texture 6 zero and 432 for texture 5 zero mass matrices, have been carried out to ascertain their compatibility with the existing quark mixing data. It seems that all the texture 6 zero possibilities are completely ruled out whereas in the case of texture 5 zero mass matrices the only viable possibility looks to be that of Fritzsch-like.

Minimal weak basis textures and quark mixing data
The phenomenology of the most general quark mass matrices with a minimum of three texture zeros obtained through weak basis (WB) transformations has been discussed within the framework of the standard model. The relationship between the textures, naturalness and WB transformations has also been studied. Adopting a ?hierarchical? parameterization for the quark mass matrix, we have detailed exact relations for the various elements of the quark mixing matrix along with the CP asymmetry angle ?, illustrating the?explicit relationship between the observed hierarchies among the WB quark mass matrices and the quark mixing matrix. Besides exploring the complete parameter space available to the (Mq)11, (q = u, d) elements in these mass matrices, their implications for quark mixing data and CP violation asymmetries have also been explored.
