Associated production of neutral toppion with a pair of heavy quarks in collisions
We have studied a neutral toppion production process in the topcolor-assisted technicolor(TC2) model. We
find that the cross section of is much
larger than that of . On the other hand,
the cross section can be obviously enhanced with the increasing of c.m.energy.
With GeV, the cross section of production can
reach the level of a few fb. The results show that is the most ideal channel to detect
neutral toppion due to the clean SM background. With such sufficient signals
and clean background, neutral toppion could be detected at TESLA with high
c.m.energy.Comment: 11 pages, 5 figure
