| dc.description | The baryon decay modes of B,bar{B}-> N_{1}bar{N}_{2}(f), bar{N}_{1}N_{2}(bar{f}) provide a frame work to test CP-invariance in baryon sector. It is shown that in the rest frame of B, N_{1} and bar{N}_{2} come out with longitudnal polarization lambda_{1}=lambda_{2}=\pm 1 with decay width Gamma_{f}=Gamma_{f}^{++}+Gamma_{f}^{--} and the asymmetry parameter alpha _{f}=ΔΓ_{f}=Γ_{f}^{++}-Gamma_{f}^{--} . It is shown that CP invariance prediction alpha_{f}=-\bar{alpha}_{bar{f}} can be tested in these decay modes; especially in the time dependent decays of B_{q}^{0}-bar{B}_{q}^{0} complex. Apart from this, it is shown that decay modes B(bar{B})->N_{1}bar{N}_{2}(bar{N}_{1}N_{2}) and subsequent non leptonic decays of N_{2},bar{N}_{2} or (N_{1},bar{N}_{1}) into hyperon (antihyperon) also provide a frame work to study CP-odd observables in hyperon decays. | |
