  1. Physics Summary & Homework Amarjit Soni HET, BNL (soni@bnl.gov) Super-B’05@Hawaii

  2. Topics • I. Possible sightings of New Physics • 1) b->s penguin dominated modes • 2) B-> Aπ K… • II. Potential use of semi-inclusive hadronic modes for NP search • III. Radiative Decays: Br`s, DIRCP, MIXCP • IV. Direct extraction of UT Olsen, Mishima,Smith, Hou, Mishima X-G He Hulsbergen,Mitov,Nishida Atwood,Gritsan<->Datta,Zupan

  3. Other topics • G. Eigen: • Y.Okada • T. Iijima • N.Satoh • H. Paes (Apologies if I missed yours) Extremely instructive ~25 talks! I learned a lot!

  4. Lumi. Benchmarx [0.2, 2, 10]/ab Impt. Things LHCb May not b able 2 do Exptal inputs That may help Theory (models) Physics Summary SBF'05 Hawaii

  5. Possible sightings of exotic b->s Penguins • Current state of theory • Current state of expt. Summary: For KS [ή,φ], ΔS>0.10 is very difficult to accommodate in the SM Summary:For KS ή there is about 2 to 2.7 σ deviation, So it is rather marginal. Does this mean we should forget about it? emphatically, no. In fact, experimentalists (or group) may easily get burnt by ignoring it! We can and must try to get to the bottom of this as quickly as possible Physics Summary SBF'05 Hawaii

  9. Glmpses from a few theoretical studies • I. London &A.S.PLB’97…use naïve quark model to suggest ΔS=0 + O(few%) for B->KS[ή,η,π,φ,ω,ρ…];but, in view of hadronic uncertainties advocate ΔS>0.1 may be problematic for the CKM-paradigm.Note, paper was basically motivated by the huge Br of ή KS discovered @ CLEO II 1) Mishima & Li (pQCD) KS[π,φ] very clean..[How about ή??] • 2)Beneke&Neubert(hep-ph/0308039) use QCDF in their study …main conclusion: KS[ή,φ] are the cleanest modes with smallest ΔS & smallest uncertainties 3)Cheng,Chua,A.S. [QCDF+FSI], KSή is cleanest; KSφ is also very clean. Physics Summary SBF'05 Hawaii

  18. Although, at the moment it is at best a marginal effect, it may well become a serious blunder on the part of experimentalists to ignore it! We can try learn some lessons from history. It is extremely important to understand that basically it is a very good test of the SM and theoretically it can be further improved Physics Summary SBF'05 Hawaii

  23. Can our theoretical understanding be improved? HOME WORK YES! • Improved measurements of Br and CP [DIRECT AND MIXING INDUCED] in related modes, such as [ή,φ,π…]K-(*) can help greatly in improving model calculations [EVEN THEORISTS CAN LEARN!] Physics Summary SBF'05 Hawaii

  24. What if improved measurements(e.g.) show ΔSήK>.20+-0.02 BOTTOMLINE It is IMPOSSIBLE that genuine NP will show up only in ή KS , many other hadronic (b ->s) final states MUST show NP effects. Furthermore, radiative and (pair)leptonic will in all likelihood be affected as well Physics Summary SBF'05 Hawaii
