Nonfactorizable contributions to weak D → PV decays
We investigate nonfactorizable contributions to two-body hadronic decays of the charmed mesons to a pseudoscalar meson and a vector meson in Cabibbo-favored, Cabibbo-suppressed and Cabibbo-doubly suppressed modes. Employing SU(3)-flavor symmetry for the nonfactorizable matrix elements, we obtain branching ratios of the decays in consistent agreement with 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.

Implications of CP asymmetry parameter sin2β on structural features of texture specific mass matrices
Abstract In the context of Fritzsch-like texture 4 zero Hermitian quark mass matrices, we have attempted to find an ‘exact’ formula for sin 2 β wherein the dependence of β on the quark masses and the elements of the quark mass matrices is visible in a simple and clear manner. This has been achieved keeping in mind the strong hierarchy of the quark masses and assuming the weak hierarchy amongst the elements of the mass matrices. This ‘exact’ formula represents a vast improvement over the leading order formula based on strong hierarchy of the elements of the mass matrices. Apart from showing the compatibility of texture 4 zero mass matrices with the present value of sin 2 β and other CKM parameters, we find interesting conclusions regarding the structural features of the mass matrices.

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.
