| description | The violation of the Charge-Parity (CP) symmetry is a phenomenon described by
the Standard Model (SM), however, its predictions for this violation are not
enough to explain the matter-antimatter asymmetry in the visible universe.
Experimentally, CP violation in hadronic decays had already been observed in
various circumstances before 2019, when the LHCb experiment at CERN first
published results reporting CPV in D-meson decays [arXiv:1903.08726v2] ($D^0
\to K^- K^+$ and $D^0 \to \pi^- \pi^+$). In this work, a study of CP violation
is carried out analysing the phenomenology of charm decays. The study of such
topic is guided by the Cabibbo-Kobayashi-Maskawa (CKM) matrix and the process
of flavour changing decays caused by the weak interaction (focusing on charm
decays). The symmetries attributed to physical conservation laws were
recognized, allowing for the possibilities of CP violation predicted by the SM
to be examined more closely. Such theoretical studies are then compared to the
results obtained by the LHCb Collaboration. Furthermore, a comparison between
CPV in charm decays and in neutrino oscillations is made, analysing the CP
violating phase in both the CKM and the Pontecorvo-Maki-Nakagawa-Sakata (PMNS)
matrices. |
