At present, althoug the standard model of electroweak interaction is very succcessful in explaining the particle theory and the observed data so far. But we are still belived that,there must exist some new physics beyond the SM,whose true nature is not yet well-known.. In this paper,we would like to study the scenario with the Unparticle physical mode in thesemileptonic rare decay modesBâ†'K(K*)1+1-,as discussed above,we found that,when the pairs of decay dileptons quality is very small, Unparticle make their branching ratio increased significantly, and their values is dependent on the scale du's.In addition, we also consideredthe forward-backward asymmetry of these processes.its values is to be enlarged too.as compared to values in the standard model.
