In minimal-supergravity-based supersymmetry models the charged sleptons as well as the sneutrinos may be lighter than the squarks. In such a light slepton scenario search for the lighter stop squark has been investigated in the dilepton + missing pT[Formula: see text](≥ 1) channel at Tevatron. In this scenario semileptonic decay of the lighter stop squark has been considered via off-shell and on-shell charginos. In the latter case the chargino undergoes pure leptonic two-body decay. We observe that for some favorable region of the MSSM parameter space one can probe the lighter stop squark mass up to 140 GeV with few events in the present data set for which the luminosity is 110 pb -1. At the MI upgrade one is likely to end up with more events.

In this paper, we calculated the supersymmetric contributions to the branching ratios and CP-violating asymmetries of the four B→Kπ decays in both the general and the constrained minimal supergravity (mSUGRA) model. Within the considered parameter space, we found that (a) the phase ϕμin the general mSUGRA model is strongly constrained by the data of the electron and neutron electric dipole moment and the data of B→Xsγ decay: ϕμ<0.1 (<10-3) for the case of small (large) tan β, but no limit on the phase ϕAcan be derived from the above data; (b) in both the general and the constrained mSUGRA model, the SUSY contributions are not large enough to explain the observed B→Kπ puzzle.

The Mathematical Model

The mathematical model of a bubble cluster subjected to an acoustic field is investigated. In this model the cluster is considered as a large drop containing a liquid and a set of microbubbles. Areas of applicability of the mathematical model of the bubble cluster in the parameter space (α, R_0) are constructed, where α is the bubble concentration in the cluster; R_0 is the initial radius of the cluster.
