====== TTP08-04 NNNLO results on top-quark pair production near threshold ======
 
 
   <hidden TTP08-04  NNNLO results on top-quark pair production near threshold > We present new results on the NNNLO top-antitop production cross section near threshold from potential and ultrasoft gluon corrections. The new non-logarithmic third-order terms are in the 10% range and lead to a significant reduction in the theoretical error.
