Unification of topological invariants in Dirac models
Gero von Gersdorff, Shahram Panahiyan, Wei Chen
Topological phases of materials are characterized by topological invariants that are conventionally calculated by different means according to the dimension and symmetry class of t…
A Clockwork Solution to the Doublet-Triplet Splitting Problem
Gero von Gersdorff
Maybe the biggest puzzle in grand unified theories (GUTs) is the apparent large splitting of the doublet and triplet Higgs masses. We suggest a novel mechanism to solve this puzzle…
Realistic GUT Yukawa Couplings from a Random Clockwork Model
Gero von Gersdorff
We present realistic models of flavor in SU(5) and SO(10) grand unified theories (GUTs). The models are renormalizable and do not require any exotic representations in order to acc…
Searching for axion-like particles with proton tagging at the LHC
Cristian Baldenegro, Sylvain Fichet, Gero von Gersdorff +1
The existence of an axion-like particle (ALP) would induce anomalous scattering of light by light. This process can be probed at the Large Hadron Collider in central exclusive prod…
