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...

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 develop a general technique for proving convergence of repeated quantum interactions to the solution of a quantum stochastic differential equation. The wide applicability of the method is illustrated in a variety of examples. Our main theorem, which is based on the Trotter-Kato theorem, is not restricted to a specific noise model and does not require boundedness of the limit coefficients.
