Resumo:

CP (charge conjugation and parity) symmetry and its violation is a
fundamental ingredient to comprehend the matter-antimatter asymmetry
of the Universe.
Although the Standard Model of particle physics can accommodate CP
violation,
it is not predicted by the model. Since 1964 we know that CP is
violated in the neutral kaon system. In the early 2000s direct CP
violation was  established with both  K-mesons and B-mesons. Recently,
in 2019, the LHCb experiment at CERN has also confirmed CP violation
with D-mesons. The observed CP violation, however, is too small to
explain the matter-antimatter disparity of the Universe.

In this colloquium we will discuss the quest for CP violation in the
most elementary particle system: neutrinos. In particular, we will
focus our attention on the lastest results of the accelerator
experiments T2K and NOvA, which are the most sensitive experiments at
the moment to CP violation in the leptonic sector. Arguably, the
importance of observing CP violation in the leptonic sector is
connected to Leptogenesis, a class of scenarios where the baryon
asymmetry of the Universe can be generated by a lepton asymmetry.

Our aim is to try to answer the question: can we already say that
neutrinos and antineutrinos do not oscillate in the same way?
