We analyze the production of the neutral Higgs particles of the Minimal Supersymmetric extension of the Standard Model at the Fermilab Tevatron collider. We consider the two main production and detection channels: gluon--gluon and bottom quark fusion leading to Higgs bosons which subsequently decay into tau leptons, $gg, b\bar b \to {\rm Higgs} \to \tau^+\tau^-$. We update the production cross sections and the decay branching ratios and obtain production rates that are significantly smaller at high masses than the ones used by the CDF and D0 experiments in their search. We then evaluate the various theoretical uncertainties that affect these rates, uncertainties that have not been been considered in the experimental analyses and which turn out to be rather large. Including these two effects will significantly loosen the constraints obtained on the supersymmetric Higgs sector at the Tevatron.

We then evaluate the various theoretical uncertainties that affect these rates, uncertainties that have not been been considered in the experimental analyses and which turn out to be rather large. Including these two effects will significantly loosen the constraints obtained on the supersymmetric Higgs sector at the Tevatron.

The issue is how to combine the uncertainties and we proceed as stated in Refs. [ref] : the cross section uncertainties are weighted according to their importance and we add linearly the decay branching ratio uncertainty which is $≃+4%,-9%$ on BR$(Φ→τ^+ τ^- ≃10%)$ [ref] .

The uncertainties come then from: $i)$ the starting point for the $b$–quark mass $m_b(m_b)= 4.19^+0.18 _-0.06$ GeV [ref] where the central value corresponds to a pole mass of $M_b=4.71$ GeV; and $ii)$ the error on the QCD coupling $α_s(M_Z^2)= 0.1171 ±0.0014$ at NNLO (the value adopted in the cross sections) [ref] which is used to run the $b$–quark mass from $m_b$ up to $M_Φ$.
