4. SuperB Physics Goals – Executive Summary  Physics capabilities published in arXiv:1008.1541.arXiv:1008.1541  Identify the flavour structure of New Physics.  Different New Physics models predict a different hierarchy of results => multiple measurements needed.  Sensitive to New Physics through flavour properties; CP Violation asymmetries in B and D decays; and rare decays.  Probe New Physics scales up to 10-100 TeV through indirect measurements.  Tests both the quark and lepton sectors.  Golden Channels (good SM prediction + good experimental resolution) e.g. inclusive b →sγ, B→Kυυ, B→τυ, τ→μυυ  Interplay with Lattice QCD predictions. 8th April 2011 Fergus Wilson, STFC/RAL4
