• The BaBar detector:– Upcoming shutdown Aug through Dec. 06- complete the upgrade of the
Instrumented Flux Return (IFR)- replace RPC’s with LST’s in the remaining 4 sectors (2 sectors were done in 2002).
– Recently completed an upgrade of the DCH electronics to reduce data flow. – Some work needed on Level 1 trigger (NOT Hardware) to prepare for possible
increases in the rate – beyond the maximum 5 KHZ. • May involve some tightening in trigger lines with possible impact on lower
priority physics.– No other major hardware work is planned on other sub-detectors.
• BaBar computing & Data Management:– New computing model in place and functioning well. Able to keep up with data
and simulation production. – Caring for BaBar data - management, quality control, calibration...- is a huge part
of the our activities and is expected to increase in importance, size and requirement for manpower in time.
• Will also require significant attention and support beyond 2008. The collaboration has just began discussing the requirements and strategy for BaBar beyond 2008.
Status of the experiment

Status of the experiment
• Physics Analysis of BaBar Data: (See the details in R. Faccini’s talk)– A well oiled analysis machine at work:
• Over 200 different analysis projects are underway
– Have published/(submitted for publication) over 200 papers so far.
– 150 abstracts submitted to ICHEP 2006 in Moscow

BaBar’s initial Physics Goals & Reach Examine breaking of the CP symmetry in B decays
The CKM Test: Does the CKM picture accommodate all CP conserving and CP violating observables
in the flavor sector?
Any room for New Physics effects?
Search for New Physics in EW & Gluonic penguin-domoniated B decays– A major focus of this phase of BaBar

CP symmetry is broken in B decays: Sin2measured in 2001 (BaBar & Belle) Direct CPV in BKBaBar & Belle)
CKM established as the primary source of CPV in laboratory (as declared by Y. Nir- ICHEP2002).
All three angles of the CKM unitarity triangle are now measured. ms is now tightly bound- the SM emerging as the winner again(Tevatron’s
part).
With the B factories in their “1/ab” phase, Tevatron onward to 4-8/fb, Cleo-c & more theoretical advancements, new goals are set for CKM observables-

The message from New Physics Fits to CKM observables (As presented at LP2005- by L. Silvestrini) –
New sources of CP violation in bd & sd are strongly constrained. New Physics contributions to the bs transitions are much less constrained & are well motivated - further emphasizing the need to pursue NP searches in bs transitions:
Gluonic penguins bsg :: rates, direct CPV, “the sin2penguin” test.
EW radiative bs :: rates, direct CPV, photon helicity.EW radiative bs ll :: rates, direct CPV, AFB(q2), polarization effects,….
Bs mixing: ms, s, (The Tevatron Territory for now)
12#
By 2002, measuring with Bseemed hopeless- penguins too large to deal with & then came along the Bsystem -longitudenally polarized system & small penguin contributions-
to an accuracy of ~11o
The Dalitz (GGSZ) method for measuring expect eventual accuracy of few degrees
The family of gluonic bs decays significantly expanded beyond Bs -and CPV measured, increasing the sensitivity to NP searches
New ways of exploiting the bsNow have access to photon helicity via BKs in addition to the rate and Direct CPV.
Many new states observed; DsJ, , X, Y, Z states- rejuvenated the world of spectroscopy and their interpretation.
We have also had a few pleasant unexpected results

•BaBar is in excellent health & able to operate, receive & deliver the physics of “1/ab” data.
•We are in the precision phase of this physics with achievable goals set for benchmark channels :
• Given the large number of observables involved, a pattern is likely to emerge showing evidence for BSM physics. If we continue to see no deviation at these precisions, it’s still a great success- a “win win” situation. We’ll end up with a precisely constrained charged current sector of the Electroweak theory as a reference point for future searches for New Physics in the LHC era.
