Description
We investigate the leading one-loop Yukawa corrections to
the process $pp -> b\bar{b}H$ in the SM. We find that the
NLO correction to the cross section is about $-4\%$ if the Higgs mass is $120$GeV.
In the limit of vanishing bottom-Higgs Yukawa coupling
the cross section is generated solely at the loop level.
This contribution is very small at $M_H\sim 120$GeV and increases with
growing Higgs mass, reaching about $+17\%$ of the cross section
when the Higgs mass is about $150$GeV. The leading Landau singularity
occurs in a scalar box integral if $M_H > 2M_W$.
