Perturbative expansion of the QCD Adler function improved by renormalization-group summation and analytic continuation in the Borel plane
We examine the large-order behavior of a recently proposed renormalization-group-improved expansion of the Adler function in perturbative QCD, which sums in an analytically closed form the leading logarithms accessible from reno...

On Renormalization of Poisson-Lie T-plural Sigma Models
Covariance of the one-loop renormalization group equations with respect to Poisson?Lie T-plurality of sigma models is discussed. The role of ambiguities in renormalization group equations of Poisson?Lie sigma model...

Rigorous Wilsonian renormalization group for impurity models with a spectral gap
The Anderson impurity model (AIM) has long served as a cornerstone in the study of correlated electron systems. While numerical renormalization group (RG) offers great flexibility for metallic reservoirs, it becomes impossi...

Atom diffusion in a simple cubic lattice: Real-space renormalization group and Monte Carlo calculations
A three-dimensional simple cubic lattice gas is investigated by using the real-space renormalization group approach with blocks of different size and symmetries.All quantities have also been obtained by Monte Carlo simulations......

Renormalization effects on the MSSM from a calculable model of a strongly coupled hidden sector
the hidden sector to the MSSM renormalization group flows is computed. For concretenessWe investigate possible renormalization effects on the low-energy mass spectrum chromodynamics with gauge group SU(2)xU(1) and...
