A search for pair production of scalar leptoquarks, each decaying into either an electron or a muon and a top quark, is presented. This is the first leptoquark search using ATLAS data to investigate top-philic cross-generational couplings that could provide explanations for recently observed anomalies in B meson decays. This analysis targets high leptoquark masses which cause the decay products of each resultant top quark to be contained within a single high-pTp_{mathrm {T}}pT​ large-radius jet. The full Run 2 dataset is exploited, consisting of 139 fb−1139~hbox {fb}^{-1}139 fb−1 of data collected from proton–proton collisions at s=13 TeVsqrt{s}=13~mathrm {TeV}s ​=13 TeV from 2015 to 2018 with the ATLAS detector at the CERN Large Hadron Collider.
