Title: CMS recent results & Higgs CP study using H->tau tau final state

Abstract: Constraining the Higgs CP property can be a powerful probe for new physics. In contrast to the SM, where the Higgs boson is an eigenstate of the CP symmetry (CP even), there are numerous examples of new physics, where the physical Higgs boson is an admixture of CP eigenstates. This seminar presents recent feasibility studies of the model-independent CP property measurement using H->tautau final state with LHC run2 data, after briefly reviewing recent CMS status and results at 13TeV. The improvement of the tau identification algorithm will be also mentioned as an important ingredient to improve the analysis sensitivity.
