Search for scalar bottom quarks and third-generation leptoquarks in $$p\overline{p}$$ collisions at $$\sqrt{s}$$ = 1.96 TeV
We present the results of a search for pair production of scalar bottom quarks ({bar b}{sub 1}) and scalar third-generation leptoquarks (LQ{sub 3}) in a data sample of 5.2 f b{sup -1} collected by the D0 experiment at the Tevatron, the p{bar p} collider at Fermilab. We assume that sbottoms decay to a neutralino ({bar {chi}}{sub 1}{sup 0}) and a b quark, and we set 95% C.L. lower limits on their production in the (m{sub {bar b}{sub 1}}, m{sub {bar {chi}}{sub 1}{sup 0}}) mass plane such that m{sub {bar b}{sub 1}} > 247 GeV for m{sub {bar {chi}}{sub 1}{sup 0}} = 0 and m{sub {bar {chi}}{sub 1}{sup 0}} > 110 GeV for 160 < m{sub {bar b}{sub 1}} < 200 GeV. The leptoquarks are assumed to decay to a tau neutrino and a b quark, and we set a 95% C.L. lower limit of 247 GeV on the mass of a charge-1/3 third-generation leptoquark.
