Physics Summary SBF'05 Hawaii Possible sightings of exotic b->s Penguins Current state of theory Current state of expt. Summary: For K S [,], S>0.10 is very difficult to accommodate in the SM Summary:For K S there is about 2 to 2.7 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 Glmpses from a few theoretical studies I. London &A.S.PLB97use nave quark model to suggest S=0 + O(few%) for B->K S [,,,,,];but, in view of hadronic uncertainties advocate S>0.1 may be problematic for the CKM-paradigm.Note, paper was basically motivated by the huge Br of K S discovered @ CLEO II 1) Mishima & Li (pQCD) K S [,] very clean..[How about ??] 2)Beneke&Neubert(hep-ph/0308039) use QCDF in their study main conclusion: K S [,] are the cleanest modes with smallest S & smallest uncertainties 3)Cheng,Chua,A.S. [QCDF+FSI], K S is cleanest; K S is also very clean.

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 What if improved measurements (e.g.) show S K >.20+-0.02 BOTTOMLINE It is IMPOSSIBLE that genuine NP will show up only in K S, many other hadronic (b ->s) final states MUST show NP effects. Furthermore, radiative and (pair)leptonic will in all likelihood be affected as well

Dealing with Theoretical subtelties QCD corrections introduce complications (though dont expect 0.1).Asy(S) becomes function of inv. mass,angle,final State, whereas all 3 collapse into a single Constant for LO analysis; schematically: dS i /dMdZ = A 0 + B i +C i M+ D i Z Where I=[K *, K,2 *,K 3 *.;K (,)] That is now HW for the exptalists do MC Important point is that INTERPERTATION IS DATA DRIVEN HW for theorists These are radiative NOT hadronic final states. Therefore calculations significantly less difficult than exclusive Hadonic FS Should be amenable to pQCD, QCDF, SCET.

Slide 77

Physics Summary SBF'05 Hawaii WHY FOLLOW THIS HOLY GRAIL? ITE provides great opportunity to nail down fundamental parameters of SM-CKM to an unprecedented precision. Most likely we will need all the precision we can muster to search for new phase(s). BSM phase(s) essentially guranteed, but in light of BF results, even if NP is O(1), its effect on B-physics need not (and is unlikely to) be large. Remember m .had to go down 3-4 orders of magnitude Remember also K ~10 -3! Even though CKM-phase is O(1)! So precision is essential..Need lots and lots of CLEAN Bs. SUPER-B is essential and LHCb unlikely to be able to do a lot that is needed.

Slide 78

Physics Summary SBF'05 Hawaii Some (more) HW for this section 1)For ( 3 ) extraction inclusion of D 0* is essentially mandatoryImplementation of separate methods (GLW, ADS,or DALITZ) is OUTDATED and INEFFICENT use of data and (wo)man power 2) Need to study SM predictions for TCA in VV channelsMUST include EWP, annihilation, realistic quark masses. Use of nave factorization here is useless. Should use pQCD, QCDF+FSI. W/o this important input estimates of EXOTICA may be misleading and likely to come to haunt us. 3) OF course VV channels are extremely informative and powerful, a SBF is essential to exploit the wealth contained therein

V.Summary on Penguin Modes 1. Very useful ANTs. S>0.10 (for many modes) -> NP K S is especially clean; to some degree also K S [HWT cal. S for K S esp. PQCD] [Note also, theory difficulty in cal. Br does NOT mean CP asy is also problematic. Recall Br(B->K S ) problematic for a long long time yet sin(2 1 / ) determination precise] 2. Current deviation ~2.7 NOT significant but demands resolution may be big folly to dismiss it. REMEMBER LEONS SHOULDER ! 3. Nothing wrong with the testinfact theory Can & will improve. 4. LHCb unlikely to be able to do most of this physics!
