Description
Leptoquarks occur in many new physics scenarios and could be the
next discovery at the LHC. In this talk we point out that
a model-independent search strategy covering all possible leptoquarks is
possible and has not yet been fully exploited. To be systematic we organize
the possible leptoquark final states according to a leptoquark matrix with
entries corresponding to nine experimentally distinguishable leptoquark
decays: any of {light-jet, b-jet, top} with any of { neutrino, e/mu; tau}. The
9 possibilities can be explored in a largely model-independent fashion
with pair-production of leptoquarks at the LHC. We review the status
of experimental searches for the 9 components of the leptoquark matrix,
pointing out which 3 have not been adequately covered. We plead that
experimenters publish bounds on leptoquark cross sections as functions of
mass for as wide a range of leptoquark masses as possible. Such bounds are
essential for reliable recasts to general leptoquark models. To demonstrate
the utility of the leptoquark matrix approach we collect and summarize
searches with the same final states as leptoquark pair production and use
them to derive bounds on a complete set of Minimal Leptoquark models
which span all possible flavor and gauge representations for scalar and
vector leptoquarks.
