The production of the neutral technicolor pseudo Goldstone bosons {ital P}{sup 0{prime}} and {ital P}{sub 8}{sup 0{prime}} at large transverse momentum in {ital p{bar p}} collisions, {ital p{bar p}}{r arrow}{ital g}({ital q}){ital P}{sup 0{prime}}({ital P}{sub 8}{sup 0{prime}}){ital X}, has been investigated at the Superconducting Super Collider (SSC) energy. The major two-body and three-body decay modes in tree diagrams are also investigated in detail. The {ital t{bar t}} decay channel would dominate the decays of both {ital P}{sup 0{prime}} and {ital P}{sub 8}{sup 0{prime}} if it is allowed. Otherwise, {ital gg} and 3{ital g} will be the dominant decay modes unless the mass of the {ital P}{sup 0{prime}} and {ital P}{sub 8}{sup 0{prime}} are below 40 GeV, where {ital b{bar b}} becomes dominant. The {ital t{bar t}} channel will be the ideal signal for detecting these bosons since the signal is much larger than the QCD background. However, in the absence of the {ital t{bar t}} channel, the {tau}{bar {tau}} mode can be used to identify {ital P}{sup 0{prime}} up to {ital m}{sub {ital P}}=300 GeV in the transverse-momentum range {ital P}{sub {perpendicular}}{approx lt}100 GeV. Similarly, the {ital b{bar b}} decay mode can serve as a useful signal for the identification of {ital P}{sub 8}{sup 0{prime}} up to {ital m}{sub {ital P}}=300 GeV for {ital P}{sub {perpendicular}} between 500 and 700 GeV. Our results show that these high-transverse-momentum production processes are useful in searching for the {ital P}{sup 0{prime}} and {ital P}{sub 8}{sup 0{prime}} at the SSC.
