This project aimed to explore the origins of matter-antimatter asymmetry in the universe by analysing CP violation in B-meson decays using data from the LHCb experiment at CERN. Our goal was to identify and quantify asymmetries that could shed light on fundamental processes beyond the Standard Model.

Working alongside another physicist, I helped develop and apply selection criteria to isolate relevant decay channels, perform statistical analysis, and interpret CP-violating signals. Our results indicated significant asymmetries consistent with the hypothesis that hadron rescattering may contribute to CP violation. We also proposed methodological improvements to increase the precision of future analyses, including refined background subtraction techniques and enhanced detector calibration.

Through this project, I gained experience in particle physics data analysis, statistical interpretation of rare decay events, and the collaborative workflow common in high-energy physics. It reinforced my understanding of how experimental evidence connects to fundamental cosmological questions.
