Unique Selling Points (USPs)  New European Accelerator Facility to be sited in Italy, ready by 2016 o At Υ(4S), 6.7 GeV positrons on 4.18 GeV electrons, 1.3 km circumference  High Luminosity (100 x current records) o ≥ cm -2 s ab -1 /year rising to 40 ab -1 /year in later years o 1 ab -1 => 1 billion B-meson pairs and 1 billion tau pairs o 75 ab -1 by 2022  Polarization o 60%-85% polarization of electron beam o Improves physics reach by factor of 2 in some regions (e.g. LFV)  ψ (3770) to ϒ (5S) and beyond o Can scan a large energy range. o Switching from low-energy to high-energy running very quick (no more than a few weeks if magnets need to be swopped).  Charm Threshold Running o 2 months running equivalent to 100 x CLEO-c dataset.  Light Source o 30 x brighter than ESRF or Diamond Light Source.  Computing o On the scale of a non-upgraded LHC experiment. 8th April 2011 Fergus Wilson, STFC/RAL3

SuperB Physics Goals – Executive Summary  Physics capabilities published in arXiv: arXiv:  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 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

Physics - The Golden Matrix  Each mode is a golden signature of New Physics.  Overlap with LHC 8th April Fergus Wilson, STFC/RAL L=Large,M=Measurable deviation from SM tan β=60 tan β=5 Sensitive region (>3 σ)

Physics – LHC and SuperB interplay 8th April 2011 Blue = LHC: Can measure m(A) [CP odd Higgs mass] Insensitivity to tanβ [ratio of Higgs vevs] Poor sensitivity to A [coupling] Red=LHC+EW/Low-energy (includes SuperB): Can build on the m(A) measurement to measure tanβ. Current analysis of data prefers tanβ ~10. 7Fergus Wilson, STFC/RAL

Physics – Charged Higgs (2HDM and MSSM) 8th April 2011 Fergus Wilson, STFC/RAL8 SuperB excludes B-Factories exclude MSSM2HDM-II B →sγ / LEP excludes ATLAS 30fb -1  Higgs-mediated Minimal Flavour Violation  Multi-TeV search capability for large tanβ.  Includes SM uncertainty ~20% from V ub and f B.  B 0 →l + l - and B 0 →l - τ + also sensitive to non-SM Higgs

SuperB – Funding and Developments  SuperB approved through primary law by Italian parliament, December 14 th /15 th  Parliament also approved INFN “Piano Triennale” funding profile which includes SuperB.  SuperB is a “Progetti Bandiera” national flagship project. 8% of national research budget allocated to flagship projects.  19M€ in 2010, 50M€ per year thereafter until EOY SuperB is the only project receiving multi-year funding so far.  ~120M$ in-kind contribution from US through use of PEP-II machine components and BaBar detector.  50M€ allocated for Tier 2 Grid computing centres in Southern Italy.  ~100M€ via Italian Institute of Technology (IIT) for beam-lines.  Only ~25M€ needed from international collaborators for detector  Conclusion: solid funding in an uncertain financial world. 8th April 2011 Fergus Wilson, STFC/RAL15

Conclusion and Outlook  August 2010: Physics, Accelerator, Detector reports published.  SuperB has been approved by the Italian Government, December 2010, as a “Flagship” project.  A unique opportunity for Europe and International Collaboration.  The necessary funding is in place.  First beams in ab -1 /year rising to 40 ab -1 /year.  Site selection to be announced May  Present participation in preparation by Italy, Canada, France, Germany, Poland, Russia, Spain, UK, US.  Collaboration is still growing.
