Phys. Rev. D 53, 1548–1552 (1996)Choice of dispersion relation to calculate the QCD correction to Γ(H→l+l-)Received 21 July 1994; published in the issue dated 1 February 1996 We use the operator product expansion of quark vacuum polarization functions to show that the dispersion relation of Kniehl and Sirlin will yield the correct result to all orders in αs when applied to the QCD correction to the leptonic decay width of the Higgs boson. i© 1996 The American Physical Society. © 1996 The American Physical Society URL:
