Energy Frontier Lepton Colliders

The website will support the Fermilab Theoretical Physics Department

Discussion Group on Energy Frontier Lepton Colliders. We hope to meet

weekly (Thursday 11 AM) to develop the physics case for e+e- and/or mu+mu-

machines that operate at scales above 1 TeV in the cms.

Tentative Outline of Project Goal:

0. Higgs at lower energy muon collider.

I. Standard Model Physics

(a) beamstrahlung

(b) Secondary Beams WW, gamma Z, ZZ, gamma gamma, ...

(c) radiative return processes

(d) Beam quality

(e) polarization?

II. Software packages? Simulations, event generators

Detector simulaton?

II. New Physics

Main issue is integrated luminosity sensitivity, forward angle block out

and polarization

(a) Contact terms

(b) generic processes (as in EHLQ)

(c) SUSY with high mass spectrum (LesHouches?)

(d) Scalar production at high energies where muon mass coupling

is advantageous?

Muon collider detector/accelerator assumptions:

(fairly liberal)

1 to 10 TeV in CMS

Perhaps polarization, but consider 0% 10 % 30% 100 %

Perhaps backward-forward blockout, polar angle 20 degrees,

possibly smaller.
