Description
We consider two BSM scenarios with scalar leptoquarks (LQ), motivated by neutrino mass, muon $g-2$, and anomalies in $B$-decay ratios. A combination of a singlet and a doublet scalar LQ can generate one-loop Majorana neutrino mass, and contribute to the observed muon and electron $g-2$ values, while satisfying bounds from lepton flavour violating decays. A carefully chosen parameter space in this model carries discovery and discernability potential at the LHC/FCC from pair production, with different finalstates. On the other hand, extending the SM with a singlet and a triplet scalar LQ separately can categorically explain the observed tensions in $B$-decay ratios. With a minimal set of couplings, the singlet contributes to $R(D)/R(D^*)$, and the triplet to $R(K)/R(K^*)$. The Yukawa couplings can be probed from single production of the LQs at the LHC/FCC, and their $5\sigma$ reach for a range of mass is studied.
