Factorization of elastic, single, and double diffractive scattering
Philipp B. Aretz, Kyle Lee, Stella T. Schindler +1
We use effective field theory techniques to factorize elastic, single, and double diffractive forward scattering in the Regge limit , where is the squared moment…

A rigorous Keldysh functional integral for fermions
Philipp Benjamin Aretz, Manfred Salmhofer
We provide a mathematically rigorous Keldysh functional integral for fermionic quantum field theories. We show convergence of a discrete-time Grassmann Gaussian integral representa…

Families of periodic delay orbits
Peter Albers, Philipp Aretz, Irene Seifert
We construct and analyze families of periodic delay orbits for a class of delay differential equations in two dimensions depending on two real-valued functions. These families are…
