Analytic Representations of Yang-Mills Amplitudes

N. E. J. Bjerrum-Bohr, Jacob L. Bourjaily, Poul H. Damgaard +1

Scattering amplitudes in Yang-Mills theory can be represented in the formalism of Cachazo, He and Yuan (CHY) as integrals over an auxiliary projective space---fully localized on th…

New Representations of the Perturbative S-Matrix

Christian Baadsgaard, N. E. J. Bjerrum-Bohr, Jacob L. Bourjaily +3

We propose a new framework to represent the perturbative S-matrix which is well-defined for all quantum field theories of massless particles, constructed from tree-level amplitudes…

New Ways to Determine Low-Energy Constants with Wilson Fermions

P. H. Damgaard, U. M. Heller, K. Splittorff

We show how the leading physical and Wilson low-energy constants associated with Wilson fermions in lattice gauge theory can be determined individually by using spectral informatio…

Hamiltonian N=2 Superfield Quantization

I. A. Batalin, P. H. Damgaard

We present a superfield construction of Hamiltonian quantization with N=2 supersymmetry generated by two fermionic charges Q^a. As a byproduct of the analysis we also derive a clas…

On Finite-Volume Gauge Theory Partition Functions

G. Akemann, P. H. Damgaard

We prove a Mahoux-Mehta--type theorem for finite-volume partition functions of SU(N_c\geq 3) gauge theories coupled to fermions in the fundamental representation. The large-volume…

The QCD Dirac Operator Spectrum and Finite-Volume Scaling

P. H. Damgaard

Random matrix theory and chiral Lagrangians offer a convenient tool for the exact calculation of microscopic spectral correlators of the Dirac operator in a well-defined finite-vol…
