Renormalizable and unitary Lorentz invariant model of quantum gravity

S. A. Larin

We analyze the R + R2 model of quantum gravity where terms quadratic in the curvature tensor are added to the General Relativity action. This model was recently proved to be a self…

The method of direct expansions of Feynman integrals

S. A. Larin

The universal method of expansion of integrals is suggested. It allows in particular to derive the threshold expansion of Feynman integrals.

Five-loop renormalization group functions of $O (n)$ -symmetric $ϕ^{4}$ -theory and $\ep$-expansions of critical exponents up to $\ep^5$

H. Kleinert, J. Neu, V. Schulte-Frohlinde +2

Motivated by the discovery of errors in six of the 135 diagrams in the published five-loop expansions of the $β$ -function and the anomalous dimensions of the $O (n)$ -symmetric $ϕ^…
