| dc.description | We analyze the four-fermion reactions e+e- -> 4f containing a single top quark and three other fermions, a possible decay product of the resonant anti-top quark, in the final state. This allows us to estimate the contribution of the nonresonant Feynman graphs and effects related to the off mass shell production and decay of the top quark. We test the sensitivity of the total cross section at centre of mass energies in the t tbar threshold region and far above it to the variation of the top quark width. We perform calculation in an arbitrary linear gauge in the framework of the Standard Model and discuss an important issue of gauge symmetry violation by the constant top quark width. | |
