Conformal Symmetry and the Standard Model
Krzysztof A. Meissner, Hermann Nicolai
We re-examine the question of radiative symmetry breaking in the standard model in the presence of right-chiral neutrinos and a minimally enlarged scalar sector. We demonstrate tha…
Curvature corrections and Kac-Moody compatibility conditions
Thibault Damour, Amihay Hanany, Marc Henneaux +2
We study possible restrictions on the structure of curvature corrections to gravitational theories in the context of their corresponding Kac--Moody algebras, following the initial…
IIA and IIB spinors from K(E10)
Axel Kleinschmidt, Hermann Nicolai
We analyze the decomposition of recently constructed unfaithful spinor representations of K(E10) under its SO(9) x SO(9), and SO(9) x SO(2) subgroups, respectively, where K(E10) is…
A note on gauge fixing in supergravity/Kac-Moody correspondences
Christian Hillmann, Axel Kleinschmidt, Hermann Nicolai
We explain how to achieve the traceless gauge for the spatial part of the spin connection in the framework of the recently proposed correspondence between the (appropriately trunca…
Loop and spin foam quantum gravity: a brief guide for beginners
Hermann Nicolai, Kasper Peeters
We review aspects of loop quantum gravity and spin foam models at an introductory level, with special attention to questions frequently asked by non-specialists.
