19. The B anomalies

Mitesh Patel (LHCb) (Imperial College London)

An overview of the anomalies observed in measurements of neutral- and charged-current b quark transitions will be presented. Experimental and theoretical challenges for the relevant measurements will be discussed, and at outlook for future developments that may give clarity presented.

20. Belle II: status and prospects

Dr Thomas Kuhr (Belle II)

The Belle II experiment at the SuperKEKB energy-asymmetric e+e− collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The target luminosity of the machine is $6\times10^{35}$ cm$^{−2}$s$^{−1}$ and the Belle II experiment aims to record 50 ab$^{−1}$ of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able to measure the...

21. Fermilab Muon g-2: from a_\mu to g

Dr Adam Schreckenberger (Fermilab g-2 collaboration)

The Fermilab Muon g-2 Collaboration recently measured the muon magnetic anomaly with an unprecedented precision of 0.46 ppm. The new result is consistent with the measurement published by the g-2 experiment based at Brookhaven National Laboratory, and a difference of 4.2 standard deviations exists between the Standard Model prediction recommended by the Muon g-2 Theory Initiative and the...

22. Theory perspective on the flavour anomalies

Dr Monika Blanke

30/06/2021, 18:55

Over the past few years, several anomalies related to the violation of lepton flavour universality emerged in charged and neutral current B meson decays, and also the longstanding tension in the muon g-2 has been strengthened by recent data. In this talk I will review possible New Physics explanations of these anomalies and discuss how they can be probed by complementary observables in the...
