Weak Radiative Decay Lambda_b to Lambda gamma and Quark-Confined Effects in the Covariant Oscillator Quark Model
Rukmani Mohanta, Anjan K. Giri, Mohinder P. Khanna +2
Motivated by the observation of the decay B to K* gamma by the CLEO collaboration, we have systematically analyzed the weak radiative decay Lambda_b to Lambda gamma, evaluating the…
Exclusive Weak Radiative Decays of B Mesons in the Covariant Oscillator Quark Model
Rukmani Mohanta, Anjan K. Giri, Mohinder P. Khanna +2
Exclusive weak radiative B meson decays are studied using the covariant oscillator quark model. The branching ratios for the processes B0 to K*0 gamma and B to K* gamma have been e…
Hadronic Weak Decays of Lambda b Baryon in the Covariant Oscillator Quark Model
Rukmani Mohanta, Anjan K. Giri, Mohinder P. Khanna +3
Cabibbo allowed two-body hadronic weak decays of Lambda b baryons are analyzed in the factorization approximation. We use the covariant oscillator quark model to evaluate the heavy…
Non-leptonic Two-meson Decays of B-Mesons in the Covariant Oscillator Quark Model with Factorization Ansatz
Rukmani Mohanta, Anjan K. Giri, Mohinder P. Khanna +3
Exclusive nonleptonic bottom meson decays are studied in the covariant osillator quark model using the factorization assumption. The main feature of this model is that it can simul…
