Abstract: Following the discovery of the Higgs boson in 2012 by the ATLAS and CMS Collaborations, studies are required to investigate its Charge-Parity (CP) properties in the Yukawa interaction with tau leptons. This talk presents an ongoing master’s thesis in the µ a1 decay channel. Different reconstruction techniques are implemented in the µ a1 channel to enhance the sensitivity to the CP properties of the Higgs boson to investigate whether its properties are CP-even, CP-odd, or CP-mixed. The a1 channel denotes the decay τ → ντ π π π. The data were collected with the CMS detector during 2022-2023 at √s = 13.6 TeV, corresponding to an integrated luminosity of 63 fb−1
