Area of Science:

  • High Energy Physics
  • Quantum Chromodynamics
  • Particle Physics

Background:

  • Dimension-five dipole operators are essential for understanding flavor-changing processes in the Standard Model.
  • Previous calculations lacked the complete three-loop anomalous dimension matrix.

Purpose of the Study:

  • To calculate the complete three-loop O(alpha(3)(s)) anomalous dimension matrix for dimension-five dipole operators.
  • To provide a key component for next-to-next-to-leading order QCD analysis of B decays.

Main Methods:

  • Perturbative quantum chromodynamics calculations.
  • Integration of heavy Standard Model particles (top quark, electroweak bosons).

Main Results:

  • The complete three-loop anomalous dimension matrix for dimension-five dipole operators has been computed.
  • This calculation advances the precision of theoretical predictions for B decays.

Conclusions:

  • The computed matrix completes the three-loop anomalous dimension matrix for operators governing low-energy flavor-changing processes.
  • This result is a vital ingredient for the next-to-next-to-leading order QCD analysis of the B--> X(s)gamma decay.
