All-Orders Renormalon Resummations for some QCD Observables

Autor: Lovett-Turner, C. N., Maxwell, C. J.

Publikováno v: Nucl.Phys.B452:188-212,1995

Exact large-$N_{f}$ results for the QCD Adler $D$-function and Deep Inelastic Scattering sum rules are used to resum to all orders the portion of QCD perturbative coefficients containing the highest power of $b$=$\frac{1}{6}(11N$--$2N_{f})$, for SU($

Renormalon Singularities of the QCD Vacuum Polarization Function to Leading Order in $1/N_{f}$

Autor: Lovett-Turner, C. N., Maxwell, C. J.

Publikováno v: Nucl.Phys. B432 (1994) 147-162

We explicitly determine the residues and orders of all the ultra-violet (UV) and infra-red (IR) renormalon poles in the Borel plane for the QCD vacuum polarization function (Adler D-function), to leading order in an expansion in the number of quark f

The Three-Jet Rate in $e^{+}e^{-}$ Annihilation

Autor: Lovett-Turner, C. N.

Publikováno v: Phys.Lett. B329 (1994) 361-363

Progress has been made on the calculation of $R_{3}$, the three-jet rate in $e^{+}e^{-}$ annihilation, in the $k_\bot $ (Durham) scheme. Using the coherent branching formalism \cite{b,c,d}, an explicit expression for $R_{3}$ is calculated. In
