Reconstruction of tau lepton decay planes for analysing the Higgs CP at CMSMate Farkas, Olena Hlushchenko, Wolfgang Lohmann, Dennis Roy, Hale Sert, Sebastian Siebert, Achim Stahl, •Lucas Wiens, and Alexander Zotz — III. Physikalisches Institut B, RWTH Aachen University, Germany

One of the three Sakharov conditions states that CP violation is needed to explain the matter-antimatter asymmetry in our universe. In order to find more occurances of CP violation, the Higgs Boson is now being investigated, so one can find out whether or not it is the CP-even Higgs Boson of the Standard Model or if it is in a mixed state of CP-even and CP-odd and a gateway to new physics.

By reconstructing the decay planes of tau leptons, one can perform the measurement of the CP mixing angle. This requires the use of impact parameters and thus it is vital for the analysis to properly determine and select well reconstructed impact parameters.
