In this talk, I'll present a search for scalar and pseudoscalar resonances decaying to top-antitop pairs in the semileptonic final state, using 8 TeV data from CMS. For the first time in this final state, interference effects with the Standard Model tt production are taken into account, and these effects will be shown to be non-negligible.
