<p class="MsoNormal"><b>Andreas Crivellin </b>(CERN) will speak about "Discovering Lepton Flavour Universality Violating New Physics".</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><u>Abstract:</u></p>
<p class="MsoNormal">Hints for the violation of lepton flavour universality (satisfied within the SM) have accumulated in recent years. In particular, deviations from the SM predictions were observed in semi-leptonic B decays (b->sll and b->ctau), in the anomalous
magnetic moment of the muon (g-2), in leptonic tau decays and di-electron searches. Furthermore, also the deficit in first row CKM unitarity, known as the Cabibbo Angle Anomaly, can be interpreted as a sign of lepton flavour universality violation. In this
talk I review the status of these anomalies and give an overview of the possible interpretations in terms of new physics models (including a discussion of low energy parity violation experiments).</p>

<p class="MsoNormal">See you tomorrow!</p>
