I. INTRODUCTION 2 In the coming years the hadron colliders at Fermilab and CERN will focus on the hunt for the Higgs boson. The large data sample currently being collected at the Tevatron will certainly lead to improved limits on the Higgs mass [1], or even evidence for its existence. The Large Hadron Collider has the potential to confirm the existence of the Higgs boson [2, 3] between the lower limit set by LEP [4] and the upper bound suggested by perturbative unitarity [5, 6]. Such claims are based on detailed analyses that clearly require reliable theoretical pre- dictions for the production cross sections and characteristics. It is well-known that leading order predictions for such quantities, based on tree-level Feynman diagrams alone, are not sufficiently trustworthy for this purpose. The calculations are plagued by large uncertainties in their overall normalization and moreover, important kinematic effects are often missed. In this paper we present results for the production of a Higgs boson in association with two jets. Our calculation is performed at next-to-leading order (NLO) using an effective Lagrangian to express the coupling of gluons to the Higgs field [7], where the trace is over the color degrees of freedom. At the order required in this paper, the coefficient C is given in the MS scheme by [8, 9], This Lagrangian replaces the full one-loop coupling of the Higgs boson to the gluons via an intermediate top quark loop by an effective local operator. The effective Lagrangian approximation is valid in the limit m$_{H}$ < 2 m$_{t}$ and, in the presence of additional jets, when the transverse momenta of the jets is not much larger than the top mass m$_{t}$ [10]. A commonly used improvement of the effective Lagrangian approximation is to multiply the resulting differential jet cross section by a ratio R given by, where σ ( gg → H ) is the total cross section. Setting x = 4 m 2 $_{t}$/m 2 H the correction for the Here v is the vacuum expectation value of the Higgs field, v = 246 GeV. L int H = C 2 H tr G$_{µν}$ G $^{µν}$.
