  The possibility of detecting a Higgs boson through several production and
decay channels is instrumental to the measurement of its couplings. In this
paper we study the pp-> ttH(H-> tau tau) channel at the LHC, for the case of a
scalar Higgs boson, and use the obtained results to improve on existing
strategies toward a model independent determination of the Higgs boson
couplings. The case of a scalar Higgs boson with mass below 140 GeV looks
particularly promising.
