             Questions for the Super B Factory Workshop
             ------------------------------------------

     What is the maximum possible luminosity, 10^36/cm^2/sec ?

     What physics is accesible with only 2 x 10^35, and for which topics is
     10^36 required ?
     How much of this physics can also be accessed by LHCb?


---------------------------------------------------------------------------
Searching for Physics Beyond the Standard Model using 
rare B decays at a super B experiment will require precise
predictions for the expected values of the observables within 
the Standard Model.

  (a) What are the expected model independent uncertainties for the
      Standard Model predictions of the various observables?
      -- Which of these predictions are dominated by experimental inputs?
      -- Which modes and what measurements, by BaBar and Belle in the
         next few years, could be helpful in improving these predictions?

  (b) What are the ranges of the SM uncertainties based on various
      models? What experimental inputs and tests could help in validating
      these models? 

-----------------------------------------------------------------------
For the vertex detector:
Can small striplets cope with the occupancy, or do we need pixels?

Do we need to have better vertex resolution with
smaller beam pipe? For what physics?

For tracking:
Will a gas based tracker work at the expected
occupancies/backgrounds?

Should we lower the solenoid filed for better
tracking of low pt particle? What physics could be done
better ?

For the DIRC/PID:
Is it possible to have a compact readout inside the magnetic field?

For the calorimetry:
Will the current CsI(Tl) crystals still be usable at the expected
occupancies and integrated backgrounds (radiation damage)?
To what extent would a change to pure CsI solve these problems?

Does the background scale with luminosity or just beam current ?
.. or both! ... and how do we model it?
----------------------------------------------------------------------

What is the maximum possible luminosity, 10^36/cm^2/sec ?

What is the limit on beam currents ? 

What is the maximum tune shift ?
