Abstract
Over the last decade, measurements probing the flavour changing neutral
current transition b->sl+l- have shown
However, interpreting the results as physics beyond the SM is complicated by
our current understanding of hadronic uncertainties in these predictions.
It is therefore essential to measure observables that are theoretically clean
and unaffected by hadronic uncertainties.
In this seminar, I will present new results on two key processes using the
complete dataset collected by the LHCb experiment so far,
in addition to a new result on B meson production that is essential for one of
these two measurements.
