Each particle has a corresponding antiparticle, essentially its mirror twin with opposite properties. According to current cosmological theories, the Big Bang should have produced equal quantities of particles and antiparticles—yet our universe is composed almost entirely of matter. This imbalance is a fundamental mystery in physics. Thanks to modern particle accelerators, we can now create and study particles and antiparticles in the laboratory. The LHCb experiment at CERN’s Large Hadron Collider was designed to study these asymmetries. In theory, converting a particle into its antiparticle requires a combined charge and parity (CP) transformation. However, the violation of this transformation predicted by an interference mechanism is insufficient to explain all the asymmetries observed in the LHCb experiment. This discrepancy raises the possibility that new fundamental physics is at play or that hadronic (strong-interaction) effects, which are not fully described by current theories, are in play. As part of the LHCb collaboration, I will investigate processes showing discrepancies, enhance analysis methods to systematically account for hadronic effects, and distinguish between signatures of possible new physics and those originating from known strong interactions within the Standard Model.
