Leptoquark Contribution to the Higgs Boson Production at the LHC Collider
Abstract
In this report we study how a light-scalar leptoquark could affect the Higgs boson production cross-section at the LHC collider. We construct the most general renormalizable and gauge invariant effective Lagrangian involving the standard model particles and a scalar, isoscalar leptoquark, η. The total cross-section for pp -> H+X is then calculated for different values of the unknown parameters λeta, meta and mH.(Here λeta is the coupling associated with the Higgs-leptoquark interaction.) We find that if λeta is moderately large and meta is around a few hundred GeV, then the cross-section is significantly larger than the standard model value.
