LHCb, while purpose built for b-physics, also functions as a general
purpose forward detector, covering the pseudo-rapidity range 2.0 to 5.0.
Measurements of top production in the LHCb acceptance have particular
sensitivity to high values of Bjorken-x, and offer complementary PDF
constraints to measurements at the central detectors. In addition, the
higher contribution from quark-initiated production to top pair
production in the forward region leads to a larger expected charge
asymmetry at LHCb than at the other experiments.
The first Run 2 measurement of top pair production in the dilepton
channel at 13 TeV will be presented, along with previous Run 1
measurements in final states accessible to both single top and top pair
production. Heavy flavour tagging strategies at LHCb will also be discussed.
