Simultaneous Block Diagonalization of Matrices of Finite Order
Ingolf Bischer, Christian Döring, Andreas Trautner
It is well known that a set of non-defect matrices can be simultaneously diagonalized if and only if the matrices commute. In the case of non-commuting matrices, the best that can…
A fully basis invariant Symmetry Map of the 2HDM
Miguel P. Bento, Rafael Boto, João P. Silva +1
We derive necessary and sufficient conditions for all global symmetries of the most general two Higgs doublet model (2HDM) scalar potential entirely in terms of reparametrization i…
Neutrino self-interactions and XENON1T electron recoil excess
Andreas Bally, Sudip Jana, Andreas Trautner
The XENON1T collaboration recently reported an excess in electron recoil events in the energy range between . This excess could be understood to originate from t…
The Hubble tension and a renormalizable model of gauged neutrino self-interactions
Maximilian Berbig, Sudip Jana, Andreas Trautner
We present a simple extension of the Standard Model that leads to renormalizable long-range vector-mediated neutrino self-interactions. This model can resolve the Hubble tension by…
On the systematic construction of basis invariants
Andreas Trautner
We describe a new, generally applicable strategy for the systematic construction of basis invariants (BIs). Our method allows one to count the number of mutually independent BIs an…
