2 00 1 An example of resonance saturation at one loop
We argue that the large-Nc expansion of QCD can be used to treat a La-grangian of resonances in a perturbative way. As an illustration of this we compute the L 10 coupling of the Chiral Lagrangian by integrating out resonance fields at one loop. Given a Lagrangian and a renormalization scheme, this is how in principle one can answer in a concrete and unambiguous manner questions such as at what...

متن کاملAn explicit example of HQET at one-loop order of perturbation theory
The axial current of one light and one heavy quark flavour is phenomenologically interesting, as the decay constant fB of the B-meson is defined by a matrix element of such a current. This matrix element requires a non-perturbative treatment, i.e. a lattice calculation. Since the bottom quark is too heavy to be included directly in Monte Carlo simulations on today’s computers, the use of effect...
متن کاملAdS4/CFT3 at One Loop
I consider semi-classical type IIA strings rotating in the AdS4 part of AdS4 × CP . The one loop sigma model corrections to this classical solution are used to compute the energy shift, and the result is found to be E − S = f(λ) lnS with f(λ) = √ 2λ− 5 ln 2 2π +O (
متن کاملOne Loop at a Time
Classic techniques for proving termination require the identification of a measure mapping program states to the elements of a well founded domain and to show that this measure decreases with each iteration of a loop in the program. This is a global termination condition — there is a single measure which must be shown to decrease over all of the loops in the program. In this abstract we look at...
