Abstract:
The study of rare b hadron decays is an effective tool for exploring new microscopic physics. The LHCb collaboration has observed several instances where the measurements of such decays deviate slightly from the predictions of the Standard Model. However, the latest LFU (Lepton Flavor Universality) update shows no deviation from the Standard Model. This prompts us to reevaluate the new physics case behind the other anomalies. We use the Standard Model effective field theory to construct a global likelihood and compare rare b decays with complementary measurements, such as high-mass Drell-Yan. We then focus on specific examples of explicit models. This talk is based on the research article 2212.10497
