Abstract

The production of the neutral technicolor pseudo Goldstone bosons P0′ and P80′ at large transverse momentum in pp¯ collisions, pp¯→g(q)P0′(P80′)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 tt¯ decay channel would dominate the decays of both P0′ and P80′ if it is allowed. Otherwise, gg and 3g will be the dominant decay modes unless the mass of the P0′ and P80′ are below 40 GeV, where bb¯ becomes dominant. The tt¯ 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 tt¯ channel, the ττ¯ mode can be used to identify P0′ up to mP=300 GeV in the transverse-momentum range P⊥≲100 GeV. Similarly, the bb¯ decay mode can serve as a useful signal for the identification of P80′ up to mP=300 GeV for P⊥ between 500 and 700 GeV. Our results show that these high-transverse-momentum production processes are useful in searching for the P0′ and P80′ at the SSC.
