Assuming the observation of a squark at the Large Hadron Collider, we
investigate methods to access its flavour content and thus gain information on
the underlying flavour structure of the theory. Based on simple observables, we
apply a likelihood inference method to determine the top-flavour content of the
observed particle. In addition, we employ a multivariate analysis in order to
classify different flavour hypotheses. Both methods are discussed within a
simplified model and the more general Minimal Supersymmetric Standard Model
including most general squark mixing. We conclude that the likelihood inference
may provide an estimation of the top-flavour content if additional knowledge,
especially on the gaugino sector is available, while the multivariate analysis
identifies different flavour patterns and can accommodate a more minimalistic
set of observables.
