Xl. Wang et al., Single top quark production in e gamma collisions and testing technicolor models - art. no. 014002, PHYS REV D, 6001(1), 1999, pp. 4002
We study the single top quark production process e(+) gamma-->t<(b nu)over
bar>(e) in various kinds of technicolor models in high energy e gamma colli
sions at the future e(+)e(-) linear colliders. It is shown that if there is
a certain charged pseudo-Goldstone-boson (PGB) coupling to <t(b)over bar>,
the <t(b)over bar>-channel PGB contribution is dominant, but the situation
is quite different from that in the neutral channel gamma gamma--><t(t)ove
r bar> due to the destructive nature of different amplitudes. At the DESY l
inear collider TESLA, the event rates in models with <t(b)over bar>-channel
PGB contributions, such as the top-color-assisted technicolor model, etc.,
are experimentally measurable. The e(+) gamma-->t<(b nu)over bar>(e) proce
ss provides a feasible test of technicolor models with <t(b)over bar>-chann
el charged PGB contributions. [S0556-2821(99)04511-7].
