In the letter from John Peoples about the  PAC's reaction to the STT, 
we were asked to "carry out more complete studies of its capabilities"
The PAC members apparently felt that reducing the trigger rate at L2, without 
significant loss of efficiency, was not enough to convince them. 
In order to answer their questions in a way which they (might?) understand,
we need to do some more studies relating to high pt physics.

Here is the list that has been floating around, with some additions and
comments.
I have added in [] the name of the person(s) that have indicated some
willingness to work on them.

(1) Higgs      [John Hobbs]
==========
  *  what is the integrated luminosity needed to see, e.g., a 100 GeV
          Higgs with and without the L2STT? 
  *  improvements from all-jets mode?
  * is there any hope to see the all-jets channel above background? 
     how would we show it is a Higgs? 
  *  does Z -> bb trigger help?
  *  if Higgs is hopeless: can we quantify benefit for technocolor?
  
  (note: Hal points out that a recent paper (hep-ph/9807349)
     "Probing Higgs Bosons with Large Bottom Yukawa Coupling
      at Hadron Colliderson Higgs production" may be relevant)
  (also recent study on Higgs mass resolution by John Womersley, Rob  Snihur 
     and Gordon Watts for Higgs/SUSY  workshop may be relevant)
     
(2)  t tbar:    [Ulrich Heintz, Brian Connolly?, Harrison Prosper?]
============
  * How well can one measure the top mass with/without STT? 
  * how much improvement due to b-jet energy scale from Z -> bb?
  * how much improvement from mass measurement in all-jets mode?  
  * how much improvement if all-jets trigger is bandwidth-limited?
   
	  
(3) single top:    [Hal Evans, Ann Heinson, Harrison Prosper?..]
================
 * What is the significance with which we can see evidence for single top 
       production with and without STT?
 * What is the precision with which we can measure the single top
       production cross section and V_tb (with and without STT)
 * What is the improvement from being able to trigger on the all-jets
       mode?
   (is there any way to make a guess as to whether there is any hope of
     recognizing single top events in the all-jet decay mode above a
      two-jet background?
    if yes, how much would this gain us in the V_tb measurement?)    
 * If we lose efficiency because of trigger rate limitations, how would
      that degrade the measurement (or how much would having more events
      improve it)?
 * what can we learn from existing studies examining the value of b-tagging for
           single top?
 * is there any hope to separate single top from the background in
          the all-jets channel?

(Note:  Ann Heinson has written a paper with Edward Boos and Sasha Belyaev
     which has  a detailed estimate, including systematic errors as well as 
     statistical,  for the predicted sensitivity to see single top in the
     l+jets/tag mode.  Ann could extend this estimate to include the hadronic
     channels, but only at  the spreadsheet level - she doesn't have a model of the
     background in the  all-hadronic channel to do detailed MC studies. The
     paper is PRD 56, 3114 (1997).)
     
(4) Z to b bbar    [Meenakshi Narain]
===============

 * how many Z -> b bbar events can we record with/without STT?
 * how well can we see     Z -> b bbar above regular QCD two-jet background?
 * how does this influence knowledge of b-jet energy scale?
 


(5) SUSY to bbbb  [Hal Evans]
================
   * Doug Norman's study did not come to very optimistic conclusions --
     could one improve on this study?
     
   * Note:  
	The new measurements of B(b to s gamma) which is now = 3.15 x 10^-4 
	rules out the point in SUGRA paramter space chosen by Doug Norman;  in
	addition, this new value also reduces the probability of seeing SUSY at
	the Tevatron. According to Howie Baer, there is still some small region
	which may offer some hope, corresponding to parameters:

          tan beta = 2 and 5
          sgn(mu) = +1 (not negative as Doug did)
          m_0 = 200,
          m_1/2 = 125,
          A_0 = 0
	  
          Dan Karmgard is willing to generate events for these parameter sets.
 
(6)  Any other hadronic modes with b's in final state?

     * technocolor? (see (1))
     * ??
     
(7) sharpening of pt threshold  [Meenakshi Narain, Jerry Blazey]  
     * how much does track thrshold sharpen
     * influence on trigger rate?
     
(8) Trigger menu:
    * trigger scenario with all the L2STT advantages built in 
    * improvements wrt the scenario w/o L2STT?
    * overall rate reductions and therefore looser trigger
          requirements even for channels that do not use the L2STT.   
	
  ** Note: in order to answer some of the questions raised in (1) to (6) above,
           we'll have to make some assumptions about bandwidth allocations to
	   certain triggers. 
      	
     
 Question: We have completely ignored b physics -- should we continue to do so?
