چکیده
We study unparticle physics effects in Λb → Λ + missing energy decay with polarized Λb and Λ baryons. The sensitivity of the branching ratio of this decay and polarizations of Λb and Λ baryons on the scale dimension dU and effective cut–off parameter ΛU are discussed. e-mail: [email protected] permanent address:Institute of Physics,Baku,Azerbaijan e-mail: [email protected]

We examine the effects of an unparticle U as a possible source of missing energy in the p-wave decays of B meson. The dependence of the differential branching ratio on the K 0 (K1)−meson’s energy is discussed in the presence of vector and scalar unparticle operators and significant deviation from the standard model value is found after addition of these operators. Finally, we have given stringe...

Some new regularities found in the pseudoscalar meson octet are reported. They invite to reconsider models where elementary fermions and composite QCD open strings can be grouped in common supermultiplets.

An attempt has been made to address the 3σ anomaly of the forward-backward asymmetry of b quark in LEP data via an unparticle sector. For most part of the parameter space except certain particular regions, the anomaly could not be explained away plausibly, when constraints from other LEP observables are taken into account.
