Description
Leptoquark (LQ) interactions can explain the deviations between $b\to c \tau \bar\nu$ and $b\to s \ell^+\ell^-$ data and Standard-Model predictions.These particles are motivated by theories with quark-lepton unification which must occur at a much higher scale M_{QLU} than the masses of the leptoquark invoked to explain the flavour anomalies. The presence of such a mass gap offers the opportunity to study LQ properties from renormalisation group effects. I present infrared fixed-point solutions for leptoquark couplings and discuss their implications for flavour anomalies and collider searches. Then I present new results on radiative corrections which render the LQ couplings probed at low and high energy different.
