Heat Kernel Methods for Multiloop Calculations in Curved Spacetime: Nonzero Spin
Igor Carneiro, Gero von Gersdorff
In a previous paper we have presented a general formalism for computing Feynman diagrams for scalar fields in curved spacetime at any loop order using heat kernel methods. The main…
Inequalities for Standard Model Yukawa Couplings
Gero von Gersdorff, Lucas Modesto
We show that the Standard Model Yukawa matrices satisfy a set of simple yet nontrivial inequalities. The relations we derive are independent of the basis used to define the fermion…
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…
