Abstract: This paper employs the H + b + jets signature in proton-proton collisions to explore the structure of the H b b ¯ couplings. The focus of the analysis lies in the decay of the Higgs boson into a photon pair, taking into account both reducible and irreducible backgrounds and a realistic simulation of the detector effects. To enhance the discrimination between signal and background, a multivariate analysis is employed to analyze the kinematic variables and optimise the signal-to-background ratio. The results indicate that the H + b + jets process can significantly contribute to the precise measurement of C P -even and C P -odd couplings between the bottom quark and the Higgs boson at the LHC and FCC-hh. Finally, a novel asymmetry is introduced for the purpose of probing C P violation within the H b b ¯ coupling, formulated exclusively based on lab-frame momenta.
