The questions attached to each talk are extracfts from the LDC scetch document. They are meant as guidelines for the speakers, but should not limit the speaker from raising additional points.

Vertex Detector issues
Vertex detector configuration, overall review of the
different options on the market
Speaker:
Marco Battaglia

10
Physics potential of vertex detector as function of beam pipe radius
The role of the beam pipe radius and its optimisation for the VTX detector
Speaker:
Sonja Hillert

11
TPC issues
How large should the TPC be? How close should the ECAL end cap be to the endplate of the TPC? How much material in front of the end cap is acceptable? How much material can be tolerated in front of the barrel calorimeter?
Speaker:
Steve Aplin

12
Forward Tracking
In the forward direction, the FTD is currently a system of pixels and disks. How important is its material. How stable is forward tracking? What are the important performance goals for tracking in the forward region?
Speaker:
Klaus Moenig

13
SI-based tracking in LDC
The SIT was introduced for track merging and for V0 efficiency reasons. These studies should be redone. Is the current SIT and SET layout optimal? Which role does the material play in the overall track reconstruction?
Speaker:
Aurora Savoy Navarro

14
Forward tracking and the TPC
How important is the FCH behind the TPC? Do we need stand-alone tracking capability in there, or is a simple device which adds one or two hits sufficient? Which technology is optimal for the FCH?
Speaker:
Lee Sawyer

15
Particle Flow review
What is the possible particle flow performance? What have we achieved? (this will be a brief summary of results which will be presented in more detail int he PF session on Monday)
Speaker:
Alexei Raspereza

16
Calorimeter optimisation
What is optimal thicknes of the ECAL/ HCAL? What is the optimal sampling structure? Is the approach used in the LDC detector so far ok, can it be improoved?

Joint session with MDI
Organizing LDC at snowmass
21
organizing LDC
Set up working groups for the main areas of detector optimsation. Prioritize the questions discussed in the morning session. Define goals for snowmass (and beyond).
How important are gaps between the calorimeter components? How important are gaps between the calorimeters and other components such as the TPC? What is the penalty for a round TPC inside an octagonal ECAL, if any? How efficient is the TPC for detecting backscattered particles. How important are these?
What is the optimal transition barrel – end cap done? Is the current scheme of a long barrel in front of the end cap optimal? Are there alternatives?

The B-field and the tracker
What quality of the field do we need in the TPC, SIT, and other detectors? How can we measure and monitor the field distortions at the required level of accuracy? Can the large distortions in the large crossing angle be accounted for? Can control samples be used to improve the knowledge of the field map? Does it make sense to eliminate the plug, at the cost of a shorter magnet and thus a less homogeneous field?
