Compare the new physics opportunities at a Linear Collider with
those elsewhere, and identify the reactions, which are best suited
or unique to electron positron machines.
Diagnostic Tests: study techniques of interpreting and identifying
the properties of new physics once a new particle or interaction has
been discovered.
Evaluate the value, priority, and importance to the physics program
of the Linear Collider performance options, such as:
initial and eventual energy reach;
integrated luminosity;
a degree of needed/useful positron polarization;
advantages of other accelerator options: gamma-gamma collisions, electron-gamma collisions,
electron-electron collisions;
Detailed issues to understand as studies go forward
include:
energy spectrum,
beam bunch structure,
other collider parameters
Organize an evaluation of key issues relating to the choice of
detector technology.
Identify common signatures and search techniques that would apply
for a broad spectrum of models.
Identify necessary detector characteristics to perform the diagnostic
tests.
Perform detector optimization studies for well-chosen classes of new
physics.This working group is part of the North American regional study on physics and detectors for future high energy electron positron colliders. This effort is part of a coordinated world wide study, with other regional studies being performed in Europe and Asia.
