Possible improvements of higgs trigger at LHC

Abstract

In this work we consider two ways to improve signal to background cross-sections ratio for higgs searchings at LHC: likelyhood method and advanced rapidity trigger. Both methods are universal enough, likelyhood method can be applied to any processes with many observables, and advanced rapidity trigger can separate any colourless scattering processes and processes with colour charge at $t$ channel.
