1. Precision tests of the flavours in the SM Model Indep. Analysis in DB=2 MFV, mainly high tanb scenarios MSSM Achille Stocchi (LAL-IN2P3/CNRS)

2. Marco has shown why it is important to study the flavour and why we need precisions to test NP scale and measure NP couplings Pantaleo has shown that we can construct an e+ e- aymmetric collider with a luminosity of 1036cm-2 sec-1 ~15 ab-1/per year a low background in the interaction region a Super Flavour Factory (SFF) I want to convince that such SFF is what we need for the purpose of studying NP in the flavour sector.

3. we are writing a Conceptual Design Report (CDR)

4. B factories has shown that a variety of measurements can be performed in the clean environment. • By doing the work of extrapolating the existing measurements and the ones which will be possible with more statistics we observe that : • Several measurements are statistically limited and so • it is worthwhile to collect >50ab-1 • - The systematics errors are very rarely irreducible and • can almost on all cases be controled with control • samples. On top of it detector improvements can be crucial for some analysis. Not yet included in the extrapolations Just one example B events continuum events D ter. Thanks to better vertex resolution we can distinguish on vertex requirements B vs continuum events ( ~factor 5 background rejection) B sec D prim.

5. We concentrate on some topics g (DK), Vub /Vcb [a(pp,rp,pp)] • superb measurements related to tree level/ ~tree level • (some depending upon LCQD caluclations) sin(2b) (Peng.) 2) superb measurements very sensitive to NP Physics AFB (Xsl+l-), AFB (K*g), ACP (K*g) and mainly in inclusive modes BK(*)nn, LFV tmg 3) several quantities depending upon LCQD calculations If Lattice QCD Calculations improve as the related experimental quantities, these measurements will be extremely powerfull Br(B  (r,w),g) Br(B ln), Br(BDtn) 4) <1% UT Fits for New Physics search (all the measurements mentioned before + others..) 6) Specific run at the U(5S) 5) charm measurements

8. Flavour tests on the SM r = 0.163 ± 0.028 h = 0.344± 0.016 r = ± 0.0028 h = ± 0.0024 about 10 times better (not all measurements yet included…)

9. Model Indep. Analysis in DB=2 C = ± 0.031 f = (± 0.5)o C = 1.24 ± 0.43 f = (-3.0 ± 2.0)o

10. Minimal Flavour Violation If couplings ~ 1 all possible intermediate possibilities Leff ~ 10/rr TeV dbq ~ 1 (couplings small as CKM elements) Leff ~ 2/rTeV dbs ~1 dbq ~ 0.1 Leff ~ 1/rTeV Leff ~ 0.2/rTeV Leff ~ 0.08/rTeV dbs ~0.1 Now it is possible to related the precision on C and f to a NP scale in the following way :. r upper limit of the relative contribution of NP dbdNP physics coupling LeffNP scale (masses of new particles) worst case r = 20%  Leff ~ 180 GeV today r = 10%  Leff ~ 250 GeV 2008 SuperB r = 1%  Leff ~ 1 TeV

11. NP scale at 350 GeV Due to the actual disagreement betweenVub and sin2b we see a slight hint of new physics Re (dd13)LLvs Im (dd13)LL superB if disagreement disapper. SM Re (dd13)LLvs Im (dd13)LL with present disagreement NP at high significance ! Constraint from Dmd Constraint from sin2bcos2b Constraint from sin2bAll constraints

12. L = 350 GeV

13. Let’s be more quantitative How to read this table, two examples. At the SuperB we can set a limit on the coupling at The natural coupling would be 1 we can test scale up to we can test scale up to SuperB will probe up to >100 TeV for arbitrary flavour structure!

14. Run at the U(5S) DGs, ASL Bs mm (LHCB will do it) exotica ( Bs gg) No Time dependent possible. It is clear that a short run (few ab-1) is extremely interesting, but we arrive after LHCb Charm physics 0.3-0.5 ab-1 D decay form factor and decay constant @ 1%  Need of running at charm threshold Dalitz structure useful for g measurement  Need of running at charm threshold CP asymmetries / Rare decays / D mixing for NP search quite difficult. Consider that running SFF 2 months at threshold we will collect 1000 times the stat. of CLEO-C t physics see Marco talk

15. Summary SFF can perform many measurements at <1% level of precision Precision on CKM parameters will be improved by more than a factor 10 NP will be studied (measuring the couplings) if discovered at LHC (in the worst scenario of MFV up to about 1TeV) if NP is not seen at the TeV by LHC, SFF is the way of exploring NP scales of the several TeV (in some scenario hundrends TeV..) … and do not forget… SFF can be a Supert-charm factory, a Bs factory….
