Two ways are presented : one based on the simple lecture of the graph of the cross section as a function of the top mass and the other based on the use of probability density functions. The final result is consistent with direct measurements but with a greater uncertainty.Moriond proceedingsHigh Energy Physics - Phenomenologytext
