Numerical regularization for 4-loop self-energy feynman diagrams

HIGHLIGHTS

  • who: You may also like and collaborators from the Department of Computer Science, Western Michigan University, Kalamazoo MI, USA. High Energy Accelerator Research Organization (KEK), Oho, Tsukuba, Ibaraki, Japan have published the Article: Numerical Regularization for 4-loop Self-Energy Feynman Diagrams, in the Journal: (JOURNAL)
  • what: The accuracy of the integration limits the accuracy of the extrapolation, hence the importance of efficient integration methods, particularly for higher dimensions.

SUMMARY

    The calculation of loop integrals is essential. The number of dimensions and the degree of difficulty of the associated integration problems . . .
