Mass estimates of the SU(2) glueball from spectral methods
David Dudal, Orlando Oliveira, Martin Roelfs
The estimation of the Källén-Lehmann spectral density from gauge invariant lattice QCD two point correlation functions is proposed, and explored via an inversion strategy based on…
Graded Symmetry Groups: Plane and Simple
Martin Roelfs, Steven De Keninck
The symmetries described by Pin groups are the result of combining a finite number of discrete reflections in (hyper)planes. The current work shows how an analysis using geometric…
Källén-Lehmann Spectral Representation of the Scalar SU(2) Glueball
David Dudal, Orlando Oliveira, Martin Roelfs
The estimation of the Källén-Lehmann spectral density from gauge invariant lattice QCD two point correlation functions is proposed, and explored via an appropriate inversion method…
Geometric invariant decomposition of SU(3)
Martin Roelfs
A novel invariant decomposition of diagonalizable matrices into commuting matrices is presented. This decomposition is subsequently used to split the fundamental r…
