Opportunities for Super B Factory Current program of PEP-II/BABAR and KEKB/Belle

could attain ~1-2 ab-1 by end of the decadeo Data samples will be about 6x larger than now and 100-200x

times larger than CLEO

o With such a large increase in sensitivity to rare decays, expect that there is a significant discovery potential

o Rich program of flavor physics/CP violation to be pursued

Even larger samples may offer opportunity to search for new physics in CP violation and rare decayso High-luminosity asymmetric e+e- colliders with luminosities

1035-1036 cm-2s-1 and up to 10 ab-1/year – “Super B Factory”o Emphasis on discovery potential and complementarity in an era when LHC is operating, along with LHCb and BTeV (?)

o Complementary flavor physics if LHC discovers SUSY, etc; discovery window if no new physics seen?

Considerations for detector systems Extrapolation of backgrounds with and

without luminosity component; spatial and/or angular distributions if significant;

Performance degradation with occupancy and projected limits; likewise radiation damage and projected limits;

Detector options for 5-10x1035 machines.

What are limits of current technologies?

Long extrapolation from current background studies, which include significant luminosity-

Monolithic Active Pixels Option for very high luminosity is MAPS =

Monolithic Active Pixels = sensor and electronics on the same substrate.o R&D on monolithic pixels has started in several places.

Possible approaches:o Integrate electronics on the high resistivity substrate

usually employed for sensors• Active components are not of the best quality• The fabrication process is highly non-standard with

large feature size (>1-2mm)o Use the low resistivity substrate of standard CMOS process

as sensor• Can use standard sub-micron process with state-of-the-

art electronics

Far from a proven technology: fundamental R&D required

Radiation-hard calorimeter options

Lutetium (+Yttrium) OxyOrthosilicate [LSO or LYSO]o Fast light output in 40ns; solves occupancy problem.o Smaller radiation length 1.15cm (CsI 1.86cm) and Moliere

radius 2.3 cm (CsI 3.8cm)o Believed to be radiation hard to 100MRad!o Currently cost is ~$40/cc; pushes radius towards 700mm

Liquid Xenono Fast light output again, within ~20ns. o Radiation length is 2.9cm: need all of radial space

between 700 and 1350mm for cryostat, liquid Xenon and readout.

o Moliere radius 5.7cm: long. sampling to separate overlaps. o Cost of Liquid Xenon is $2.5/ccBoth Rad Hard crystal and Liquid Xenon options require EMC inner radius reduction to about 70cm: need to replace DRC

bars as well


Muon/KL upgrades

Forward endcap RPCs will not survive 2x1035

o Outer layers see large LER background (part of which will be shielded after summer 2004)

o Inner layers see large Lumi background at small radii Plan already in the works to replace forward

endcap with LSTs (in avalanche mode) Barrel LSTs installed in summer 2004 and

again summer 2005 should be ok for all scenarios

Not clear if there is interest in replacing backward endcap RPCs due to limited acceptance loss

Important factors in upgrade direction Project is “tunable”

o Can react to physics developmentso Can react to changing geopolitical situation

• Project anti-commutes with linear collider• Will emerge from BABAR and Belle, but could be attractive

to wider community in context of other opportunitieso As we learn more about machine and detector requirements

and design, can fine tune goals and plans within this framework

Project has headroomo Major upgrades to detector and machine, but none

contingent upon completing fundamental R&Do Headroom for detector up to 5 x 1035; with thin pixels beyondo Headroom for machine up to 8.5 x 1035; requires additional rf,

which can be staged into machine over time

Conclusions

Strong physics case for Super B Factoryo Program rests on ability to explore of new physics through

flavor couplings and phases• Complementary to LHC collider experiments• Complementary to hadron b experiments; could even

be viewed as natural successoro Precision Standard Model physics a second fundamental

pillar of programo Builds on proven track record of high-luminosity storage

rings and general purpose e+e- detectorso Builds on our present knowledge of CP violation and rare B

decays; expect that case will only strengthen as we explore ever increasing data samples over the next few years

Feasible & complementary to LHC/ILC for exploring New Physics


Conclusions

Arguments will evolve with time and datao Perhaps our data is already hinting at new physics, which

will motivate further precision studies of flavor physicso Perhaps LHC will directly see new physics, with new

couplings and phases that need to be explored at a Super B Factory

Next Stepso Working towards merging Super B efforts with Belle and

engaging wider community in exploring physics capabilities

o Super KEKB seeking approval and funding in Japano Super PEP moving to develop a conceptual and technical

design for a very high luminosity facility

Joint Super B Workshop in Hawaii in spring 2005

Aim is to get a Super B Factory operational early in the next decade
