阈附近顶夸克对产生的NNNLO结果

NNNLO results on top-quark pair production near threshold

M. Beneke, Y. Kiyo, K. Schuller

摘要:

我们提出了新的结果NNNLO的顶-反顶生产截面阈值附近的潜在和超软胶子修正。新的非对数三阶项在10%范围内,并导致理论误差的显着减少。

英文摘要:

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.
