Right handed current and two body hadronic charm decays
To the conventional four quark scheme with (V − A) × (V − A) interaction we add an admixture of a right handed current of kind . The consequences of the resulting new piece in the weak Hamiltonian of the form (V −A) × (V + A) to (D+,D0,F+) → 2P decays are investigated.

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.

SU(3){sub flavor} analysis of two-body weak decays of charmed baryons
We study two-body weak decays of charmed baryons {Lambda}{sub c}{sup +}, {Xi}{sub c}{sup +}, and {Xi}{sub c}{sup 0} into an octet or decuplet baryon and a pseudoscalar meson employing the SU(3) flavor symmetry. Using certain measured Cabibbo-favored modes, we fix the reduced amplitudes and predict the branching ratios of various decays of charmed baryons in the Cabibbo-enhanced, -suppressed, and -doubly-suppressed modes. {copyright} {ital 1997} {ital The American Physical Society}

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.

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.
