<p>A generator-level study of dilepton ttbar events to search for light charged Higgs bosons at the LHC is presented with the aim of finding a new variable to discriminate between charged Higgs signals and Standard Model signatures. The spin effects in leptonic decays of H<sup>±</sup> and W bosons are studied and a new angular distribution is identified as a discriminating variable. Studies are performed for different charged Higgs masses at two different center ofmass energies. Monte Carlo samples of Z+jets production are also used to test the analysis.</p>
