Abstract
It is shown that for intermediate Higgs masses, in the range 0.3- 0.6 TeV, the contribution σT of the transversely polarized gauge bosons (V) to the process qq→qqVV→qqH, in the leading log (LL) Equivalent Vector Boson Approximation (EVBA) is comparable to the contribution σL of the longitudinal ones. As a result the LL EVBA for σ=σL+σT overestimates the exact total cross-section by ~100-200 % at the q1q2 centre of mass energies of interest for SSC; viz. 5-10 TeV. An improved formulation of the EVBA leads to modified vector boson densities. These densities lead to an EVBA estimate, including the transverse contributions, which agrees with the exact calculation, for mH as low as 0.3 TeV, within 20-30 % upto quark energies ~5-10 TeV.
