- Choice of dispersion relation to calculate the QCD correction to Gamma(H->l(+)l(-))Takeuchi, Tatsu; Grant, Aaron K.; Worah, Mihir P. (American Physical Society, 1996-02-01)We use the Operator Product Expansion (OPE) 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.
- The difficulties involved in calculating $δρ$Takeuchi, Tatsu; Grant, Aaron K.; Worah, Mihir P. (1995-04)We discuss the difficulties that arise when one tries to calculate $\delta\rho$ using dispersion relations.
