Quantumchromodynamic corrections for ΔF=2 processes in the presence of a heavy top quark

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We calculate the QCD corrections to the ΔS=2 and ΔB=2 transition amplitudes for the casem t ≫m w and extrapolate the results tom t ≲m w , where they join smoothly with the low mass calculations,m t ≪m w . We present explicit formulas for the corrections with numerical results summarized in tables and figures and compare them with earlier calculations. We arrive at a QCD corrected effective Hamiltonian which must hold for all ranges ofm t .
