D decays into pseudoscalar and scalar mesons
In this paper, we study the pseudoscalar-scalar meson (PS) weak decays ofD-mesons in the non-relativistic quark model using factorization scheme. Branching ratios for the Cabibbo angle-favored decays are calculated.

Magnetic moments of baryons in broken SU(4)
Assuming that the anomalous magnetic moment interaction has the formaT11 +bT22 +cT44 +sTαα in SU(4), which may arise due to symmetry breaking or some other dynamical effects, we have obtained the magnetic moments and the transition moments of the ordinary and charmed baryons.

$B_c$ Meson Form-factors and $B_c \to PV$ Decays Involving Flavor Dependence of Transverse Quark Momentum
We present a detailed analysis of the ${B}_{c}$ form factors in the Bauer-Stech-Wirbel framework, by investigating the effects of the flavor dependence on the average transverse quark momentum inside a meson. Branching ratios of two-body decays of ${B}_{c}$ mesons to pseudoscalar and vector mesons are predicted.

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}

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.

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.
