Measuring Matter-Antimatter Asymmetries at the LHC
This project explored 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.
What I did
- Developed and applied selection criteria alongside another physicist to isolate relevant decay channels, perform statistical analysis, and interpret CP-violating signals.
- Found significant asymmetries consistent with the hypothesis that hadron rescattering may contribute to CP violation.
- Proposed methodological improvements for future analyses, including refined background subtraction techniques and enhanced detector calibration.
What I took away
- Experience in particle physics data analysis, statistical interpretation of rare decay events, and the collaborative workflow of high-energy physics.
- A stronger understanding of how experimental evidence connects to fundamental cosmological questions.
