Query: Introducing the Little Higgs   Little Higgs theories are an exciting new possibility for physics at TeV
energies. In the Standard Model the Higgs mass suffers from an instability
under radiative corrections. This ``hierarchy problem'' motivates much of
current physics beyond the Standard Model research. Little Higgs theories offer
a new and very promising solution to this problem in which the Higgs is
naturally light as a result of non-linearly realized symmetries. This article
reviews some of the underlying ideas and gives a pedagogical introduction to
the Little Higgs. The examples provided are taken from the paper "A Little
Higgs from a Simple Group", by D.E. Kaplan and M. Schmaltz.
