SUSY Higgs searches at DO, Tevatron

During Run II of the Tevatron collider, DO collaboration has made extensive searches for the neutral MSSM Higgs bosons (phi), produced in p (p) over bar collisions at root s = 1.96 TeV. Two such analyses addressing inclusive phi production with phi -> tau(+)tau(-), and associated phi b(b) production with phi -> b (b) over bar are reported here. No excess of events above the background expectation has been observed in any of these analyses. The results are combined to set constraints on the MSSM parameter space.
