In regions of large tanbeta and small mAlpha, searches for heavy neutral minimal supersymmetric standard model (MSSM) Higgs bosons at the Tevatron are promising. At the same time, rates in direct dark matter experiments, such as CDMS, are enhanced in the case of large tanbeta and small mAlpha. As a result, there is a natural interplay between the heavy, neutral Higgs searches at the Tevatron and the region of parameter space explored by CDMS. We show that if the lightest neutralino makes up the dark matter of our universe, current limits from CDMS strongly constrain the prospects of heavy, neutral MSSM Higgs discovery at the Tevatron unless |mu| greater or approximately 400 GeV. The limits of CDMS projected for 2007 will increase this constraint to |mu| greater or approximately 800 GeV. If CDMS does observe neutralinos in the near future, however, it will make the discovery of Higgs bosons at the Tevatron far more likely.
在tanβ较大且mα较小的区域，在Tevatron对重中性最小超对称标准模型（MSSM）希格斯玻色子进行搜索很有前景。与此同时，在tanβ较大且mα较小的情况下，诸如CDMS等直接暗物质实验中的速率会提高。因此，在Tevatron对重中性希格斯玻色子的搜索与CDMS所探索的参数空间区域之间存在自然的相互作用。我们表明，如果最轻的中性伴随子构成了我们宇宙的暗物质，那么除非|μ|大于或约为400 GeV，否则CDMS目前的限制会强烈限制在Tevatron发现重中性MSSM希格斯玻色子的前景。预计2007年CDMS的限制将把这个约束提高到|μ|大于或约为800 GeV。然而，如果CDMS在不久的将来确实观测到中性伴随子，那么它将使在Tevatron发现希格斯玻色子的可能性大大增加。
