We discuss the phenomenology of the lightest SU(3)C singlet and nonsinglet technihadrons in the straw man model of low-scale technicolor (TCSM). The technihadrons are assumed to be those arising in top-color-assisted technicolor models in which top-color is broken by technifermion condensates. We improve upon the description of the color-singlet sector presented in our earlier paper introducing the TCSM [K. Lane, Phys. Rev. D 60, 075007 (1999)]. These improvements are most important for subprocess energies well below the masses of the ρT and ωT vector technihadrons and, therefore, apply especially to e^+e^− colliders such as CERN LEP and a low-energy linear collider. In the color-octet sector, we consider mixing of the gluon, the coloron V8 from top-color breaking, and four isosinglet color-octet technirho mesons ρT8. We assume, as expected in walking technicolor, that these ρT8 decay into ¯qq,gg, and gπT final states, but not into πTπT, where πT is a technipion. All the TCSM production and decay processes discussed here are included in the event generator PYTHIA. We present several simulations appropriate for the Fermilab Tevatron collider, and suggest benchmark model lines for further experimental investigation.
