Probing the CP nature of the Higgs coupling in tt¯h events at the LHC
Amor dos Santos, S.; Fiolhais, Miguel C. N.; Frederix, R.; Gonçalo, R.; Gouveia, E.; Martins, R.; Onofre, A.; Pease, C. M.; Peixoto, H.; Reigoto, A.The determination of the CP nature of the Higgs coupling to top quarks is addressed in this paper, using t¯th events produced in √s=13 TeV proton-proton collisions at the LHC. Dileptonic final states are employed, with two oppositely charged leptons and four jets, corresponding to the decays t→bW+→bℓ+νℓ, ¯t→¯bW−→¯bℓ−¯νℓ, and h→b¯b. Pure scalar (h=H), pure pseudoscalar (h=A), and CP-violating Higgs boson signal...
Angular distributions in tt¯H(H→bb¯) reconstructed events at the LHC
Amor dos Santos, S.; Araque, Juan Pedro; Cantrill, R.; Castro, Nuno F.; Fiolhais, Miguel C. N.; Frederix, R.; Gonçalo, R.; Martins, R.; Santos, R.The associated production of a Higgs boson and a top-quark pair, tt¯H, in proton-proton collisions is addressed in this paper for a center of mass energy of 13TeV at the LHC. Dileptonic final states of tt¯H events with two oppositely charged leptons and four jets from the decays t→bW+→bℓ+νℓ, t¯→b¯W−→b¯ℓ−ν¯ℓ and h→bb¯, are used. Signal events, generated with MadGraph5_aMC@NLO, are fully reconstructed by applying...
