Ultraviolet divergences in extended supergravity
M. J. Duff
TL;DR
This paper reviews the ultraviolet divergence behavior in extended supergravity theories, highlighting how increasing the number of supersymmetries N improves their ultraviolet properties.
Contribution
It provides a comprehensive review of the ultraviolet divergences in N-extended supergravity, summarizing recent findings and their implications.
Findings
Ultraviolet divergences decrease with higher N
Enhanced supersymmetry improves ultraviolet behavior
Recent calculations support improved ultraviolet finiteness
Abstract
Recent calculations have confirmed the belief that the ultraviolet behaviour of N-extended supergravities improves with increasing N. We give a comprehensive review.
