Hints for a Geon from Causal Dynamic Triangulations
Axel Maas, Simon Plätzer, Felix Pressler
The existence of geons, physical states of self-bound gravitons, has long been proposed. In the context of four-dimensional causal dynamical triangulation simulations we investigat…
Spectrum of the SU(2) scalar-fermion-gauge system under the influence of the Brout-Englert-Higgs effect
Georg Wieland, Axel Maas
Gauge invariance requires physical states to be composite, even in the weak sector of the Standard Model (SM). The Fröhlich-Morchio-Strocchi (FMS) mechanism resolves this subtlety…
Composite objects in quantum (super)gravity
Axel Maas, Simon Plätzer, Felix Pressler
It has been a long entertained idea that self-bound gravitons, so-called geons, could be a dark matter candidate or form (primordial) black holes. The development of viable candida…
The observable spectrum for GUT-like theories
Elizabeth Dobson, Axel Maas, Simon Plätzer +1
The spectrum of nonabelian gauge theories cannot be described in terms of elementary particles, and so must be constructed from gauge-invariant composite operators, even in the pre…
