Abstract
The possibility of formation for a bound state of a t quark
and a lighter one is investigated using potential model predictions
and heavy quark effective theory approach. Resulting estimates for the
1S-2S splitting of the energy levels are compared to the total
top decay width 
. As for the case of toponium, our
conclusions show that the probability of formation for T-mesons
is negligibly small due to the high top mass value.
