A Renormalization Group Improved Calculation of Top Quark Production near Threshold
A. H. Hoang, A. V. Manohar, I. W. Stewart +1
The top quark cross section close to threshold in annihilation is computed including the summation of logarithms of the velocity at next-to-next-to-leading-logarithmic ord…
The renormalization group for correlated scales: one-stage versus two-stage running
Aneesh V. Manohar, Joan Soto, Iain W. Stewart
Nonrelativistic bound states have two low energy scales, a soft scale mu_S of order mv and an ultrasoft scale mu_U of order mv^2. In two-stage running, the soft and ultrasoft scale…
The QCD Coupling Constant
Ian Hinchliffe, Aneesh V. Manohar
This paper presents a summary of the current status of determinations of the strong coupling constant alpha_s. A detailed description of the definition, scale dependence and inhere…
Logarithms of alpha in QED bound states from the renormalization group
Aneesh V. Manohar, Iain W. Stewart
The velocity renormalization group is used to determine ln(alpha) contributions to QED bound state energies. The leading order anomalous dimension for the potential gives the alpha…
The QCD heavy-quark potential to order v^2: one loop matching conditions
Aneesh V. Manohar, Iain W. Stewart
The one-loop QCD heavy quark potential is computed to order v^2 in the color singlet and octet channels. Several errors in the previous literature are corrected. To be consistent w…
Running of the heavy quark production current and 1/k potential in QCD
Aneesh V. Manohar, Iain W. Stewart
The 1/k contribution to the heavy quark potential is first generated at one loop order in QCD. We compute the two loop anomalous dimension for this potential, and find that the ren…
