Abstract Precision flavour observables play an important role in the interpretation of results at the LHC in terms of models of new physics. We present the result for the one-loop Z penguin in generic extensions of the standard model which exhibit exact perturbative unitarity. We use Slavnov-Taylor identities to study the implications of unitarity on the renormalisation of the Z pengu... https://www.markbroyard.com/super-value-krowne-18-x84-back-bar-drain-board-and-sink-sale-limited-save/
