Predictions of Bc meson decay emitting pseudoscalar and heavy scalar mesons using ISGW II model
Two-body hadronic weak decays of B{sub c} meson emitting pseudoscalar and heavy scalar mesons are investigated using the Spectator Quark Model. Decay amplitudes are obtained using the factorization scheme; consequently, branching ratios are predicted in the Isgur-Scora-Grinstein-Wise (ISGW II) model.

SU(4) symmetry structure of the nonleptonic weak interaction
Starting with the most general SU(4) weak Hamiltonian and assuming the nonexoticity of intermediate states and s-u channel symmetry, we obtain that the parity-violating (parity-conserving) Hamiltonian belongs to 15/sub A/ direct-sum 45 direct-sum 45* (15/sub S/ direct-sum 20'' direct-sum 84).

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.

Strong coupling and hadron masses
We study the hadron mass spectrum with a decreasing strong quark–gluon coupling with an increasing mass of quark flavours. Charm hadron masses are predicted in this scheme.

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.

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.
