Pheno Seminar On Particle Physics

ABSTRACT

The behavior of matter is ruled by the standard model of particle physics, really? Old puzzles and new evidence from precision measurements are lurking and pose challenges to standard theory. Deviations in processes as rare as one in a billion suggest that electrons and muons are more different than thought: they should behave the same according to the standard model, yet recent data from the Large Hadron Collider in Geneva finds them to behave differently. If taken at face value, this anomaly heralds a very loud breakdown of the standard model and requires out-of-the-box new physics. Intriguingly, cracking this with leptoquarks, i.e., new particles which share features from quarks and leptons alike, also opens doors into the notorious and longstanding flavor puzzle. This talk reports the rise of anomalies in flavor physics, rare decays of beauty quarks and further cracks in the building.
