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…
Subleading Higgs effects at lepton colliders
Axel Maas, Duifje M. van Egmond, Simon Plätzer
Subtle field-theoretical effects suggest the presence of additional Higgs contributions in standard model processes. This has been supported by electroweak lattice calculation, e.\…
