Top-quark decay into Upsilon-meson

Abstract

The calculation of the partial width of the rare t-quark decay into Upsilon-meson, W-boson and b-quark (t -> ΥW b) is presented. The branching ratio equals Br(t -> Upsilon W b) = 1.3 * 10^{-5} that make possible searches for this rare $t$-quark decay at LHC.
