Recent preliminary results obtained by the CDF and DØ Collaborations on searches for Higgs bosons beyond the Standard Model at Run II of the Tevatron are discussed. The data, 6 corresponding to integrated luminosities of up to 1 fb−1, are compared to theoretical expectations. 2 No significant excess of signal above the expected background is observed in any of the various ] final states examined, and so limits at 95% Confidence Level (CL) are presented. x e PACS.
