Physics at e+ e- Linear Collider
There are serious interests in building an electron position linear
collider for every 8 hours time zones: US, Europe, and Japan,
to explore physics of electroweak symmetry breaking and beyond. Here
are some contributions of myself and links to other sites.

"Physics Prospects ---Why do we want a Linear Collider?--"
The need to understand physics of electroweak symmetry breaking is
reviewed. An electron positron linear collider will play crucial roles
in that respect. It is discussed how the LHC and a linear collider need
each other to understand symmetry breaking mechanism unambiguously. Two
popular scenarios, supersymmetry and technicolor-like models, are
used to demonstrate this point.
"Physics Opportunities of e+ e- Linear Colliders" by Hitoshi Murayama
and Michael E. Peskin
We describe the anticipated experimental program of an $\ee$ linear collider
in the energy region 500 GeV--1.5 TeV, emphasizing topics relevant to the
mystery of electroweak symmetry breaking.

Precision Study of Supersymmetry at Future Linear $e^+ e^-$ Colliders
by Toshifumi Tsukamoto, Keisuke Fujii,
Hitoshi Murayama, Masahiro Yamaguchi, and Yasuhiro Okada
- We discuss a possible strategy for supersymmetry searches and
studies at future linear $e^+e^-$ colliders.
We demonstrate their effectiveness by
Monte Carlo analyses with full angular correlations under realistic
experimental conditions including initial state radiation and
beamstrahlung effects. The importance of precision measurements of
supersymmetry parameters is emphasized.
We demonstrate that the precision on mass
measurements can be as good as 1~\% for leptonic and 3~\%
for hadronic final states. A detailed study on the first
superparticle alone gives us an upper bound on the next superparticle.
We can also test the basic mass relations assumed in grand unified models
or supergravity, such as the gaugino mass relations
or the universal scalar mass assumption in a variety of ways.
The polarized electron beam plays a crucial role in this study.
