Abstract: The effects of the finite top quark width in the top pair production crosssection close to the threshold are discussed in this talk. We introduce a$t\bar{t}$ cross section with a cut on the invariant masses of the top andantitop that can be calculated theoretically with effective field theory EFTmethods. The matching procedure to implement the physical phase-spaceboundaries in the NRQCD framework phase-space matching- is brieflyoutlined.
