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.

is essential for this goal
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!
