The paramagnetic phase of the two-channel Kondo lattice model is exami
ned with a quantum Monte Carlo simulation in the limit of infinite dim
ensions. We find non-Fermi-liquid behavior at low temperatures includi
ng a finite low-temperature single-particle scattering rate, no Fermi
distribution discontinuity, and zero Drude weight. Both the optical an
d quasiparticle mass enhancement and scattering relaxation rate show c
onsistent evidence of non-fermi-liquid behavior. However, the low-ener
gy density of electronic states is finite.
