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…
