Abstract
The goal of this research is to analyze the $\Lambda^0_{b} \rightarrow \Lambda^0 J/\psi$ and the $\overbar{\Lambda}^0_{b} \rightarrow \overbar{\Lambda}^0 J/\psi$ decays at the LHCb experiment, to test matter-antimatter symmetry. The presence of asymmetry in the ratio of the particle and antiparticle counts could suggest the presence of CP violation effects, which are one avenue of research when investigating physics beyond the Standard Model. The data analysis was conducted on the Run 2 data (years 2016 to 2018), using proton-proton collisions at $13$ TeV with a luminosity of $5.4$ fb$^{-1}$. The particle-antiparticle ratio was determined to be $2.0 \pm 1.5 \%$, which is not statistically significant, meaning that no asymmetry was observed. Subsequently, this means that no CP violation effects were detected.
