Using this information, we present new constraints on the flavour structure of up-type squark mass matrices in supersymmetric extensions of the Standard Model.4 pages, 3 figures. v2: additional measurements added, analysis improved, B-parameters added. v3: experimental numbers updated, final version to appear in PLBHigh Energy Physics - Phenomenologytext
