Description
In the Standard Model (SM), the Higgs boson is predicted to be a scalar with no CP-violating interactions. After the observation of the Higgs boson production in association with a top quark pair (ttH), the measurement of an odd charge-parity (CP) component in one of the Higgs boson couplings would constitute an important discovery of physics beyond the SM. This poster describes the search for a CP-odd contribution in the ttH production in the H->bb decay channel, based on the 139 fb⁻¹ of proton-proton collision data at center-of-mass energy of 13 TeV collected with the ATLAS detector.
