| Abstract | One exciting possibility of new physics beyond the Standard Mo el is that the fundamental Higgs sector is replaced by a strongly-interacting gauge theory, known as technicolor. A viable theory must break chiral symmetry dynamically, like in QCD, to gene rat Goldstone bosons which become the longitudinal components of the W± andZ. By measuring the eigenvalues of the Dirac operator, one can determine if chiral symmetry is in fact spo ntaneously broken. We simulate SU(3) gauge theory withns = 2 and 3 staggered flavors in the fundamental representation, corresponding toNf = 8 and 12 flavors in the continuum limit. Although our first findi gs show that both theories are consistent with dynamically broken chira l symmetry and QCD-like behavior, flavor breaking effects in the spectrum may require further c larifications before final conclusions can be drawn. We also compare various improved staggered act ions, to suppress this potentially large flavor breaking. |
