MC events for the process
p,P->t, tbar -> e, nu, j, j, b, B
have been generated by CompHEP 41.10 taking into
account the spin correlations in all decays.
The contribution of sea quarks in the initial
state has been included.

The following subprocesses are included:

Upper letters means antiparticles
E1 - positron
e1 - electron
n1 - electron neutrino
G - gluon
