| ABSTRACT: |
The Higgs boson is the last particle to be discovered yet to unravel the symmetry breaking mechanism of Standard Model and its production is one of the most wanted processes at the present collider Tevatron in Fermi-Lab and the upcoming Large Hadron Collider in CERN. The dominant production mechanism, namely gluon fusion process, is plagued by large QCD radiative corrections and the associated renormalisation and factorisation scale dependences leaving the predictions with large theoretical uncertainties. We will discuss some of the recent two loop QCD results that reduce these uncertainties making the predictions very accurate and stable. We also show how Sudakov resummation of soft gluons can predict partial soft plus virtual contributions at three loop level and beyond.
