Hadronic decays of $\bm{\chi_{bJ}}$ into light bottom squarks
Abstract
We calculate the rates for inclusive hadronic decay of the three states into a pair of light bottom squarks as a function of the masses of the bottom squark and the gluino. We include color-singlet and color-octet configurations. The color-octet contribution is found to be insignificant for the but can dominate in the case if current lattice estimates are used for the color-octet matrix element. In comparison with the standard model values, bottom squark decays can increase the predicted hadronic width of the by as much as 35%, for very small bottom squark masses and gluino masses in the range of 12 GeV, but make a small contribution in the cases of and . Data from decays of the states could provide significant new bounds on the existence and masses of supersymmetric particles.
