Confronting the vector leptoquark hypothesis with new low- and high-energy data
In light of new data we present an updated phenomenological analysis of the simplified [Formula: see text] -leptoquark model addressing charged-current B-meson anomalies. The analysis shows a good compatibility of low-energy data (dominated by the lepton flavor universality ratios [Formula: see text...

Sumario: | In light of new data we present an updated phenomenological analysis of the simplified [Formula: see text] -leptoquark model addressing charged-current B-meson anomalies. The analysis shows a good compatibility of low-energy data (dominated by the lepton flavor universality ratios [Formula: see text] and [Formula: see text] ) with the high-energy constraints posed by [Formula: see text] Drell-Yan data. We also show that present data are well compatible with a framework where the leptoquark couples with similar strength to both left- and right-handed third-generation fermions, a scenario that is well-motivated from a model building perspective. We find that the high-energy implications of this setup will be probed at the 95% confidence level in the high-luminosity phase of the LHC. |
