Popis: The alignment phenomenon, that the 125 GeV h0 boson so resembles the Standard Model Higgs boson, can be understood in a two Higgs doublet model without discrete symmetry. New Yukawa couplings ρtt and ρtc offer new avenues to discover the extra scalar H0 and pseudoscalar A0. We propose to search for cg→tH0, tA0 followed by H0, A0→tt¯, tc¯, where same-sign dileptons could be the harbinger, with triple-top, in the signature of three leptons plus three b-jets, as confirmation. Discovery could touch upon the origin of baryon asymmetry of the Universe.
