Symmetry-preserving discretization of variational field theories
A. C. Casimiro, C. Rodrigo
The present paper develops a variational theory of discrete fields defined on abstract cellular complexes. The discrete formulation is derived solely from a variational principle a…
Writing CFT correlation functions as AdS scattering amplitudes
Joao Penedones
We explore the Mellin representation of conformal correlation functions recently proposed by Mack. Examples in the AdS/CFT context reinforce the analogy between Mellin amplitudes a…
Finite temperature corrections and embedded strings in noncommutative geometry and the standard model with neutrino mixing
Rachel A. D. Martins
The recent extension of the standard model to include massive neutrinos in the framework of noncommutative geometry and the spectral action principle involves new scalar fields and…
Few body impulse and fixed scatterer approximations for high energy scattering
R. Crespo, A. M. Moro, I. J. Thompson
The elastic scattering differential cross section is calculated for proton scattering from He at 717 MeV, using single scattering terms of the multiple scattering expansion of…
