Leptoquarks at high and low energies — •Felix Wüst, Marco Fedele, and Ulrich Nierste — Institut für Theoretische Teilchenphysik (TTP), Karlsruher Institut für Technologie (KIT)

I consider the case that quarks and leptons are unified at some high scale. The so-called flavour anomalies, which have built up in the data of recent years, are usually interpreted in terms of leptoquarks (LQ) with masses in the multiple-TeV range. I present the renormalisation group equations which connect the LQ couplings at the fundamental high scale with those at the low scale probed in the flavour experiments and discuss phenomenological implications.
