Description

The recent intriguing hints for new physics in semi-leptonic B decays point towards lepton flavor universality (LFU) violating extensions of the SM. Prime candidates for such new particles are leptoquarks which can provide the desired effects. After a review of the current experimental and theoretical situation, the phenomenology of the vector leptoquark SU(1) singlet, which was proposed already a long time ago in the context of the famous Pati-Salam model, is discussed. A focus will be laid on important loop-effects, which allow for LFU conserving new physics alongside of LFU violating one.
