N to Delta transition form factors with Nf=2+1 domain wall fermions
C. Alexandrou, G. Koutsou, J. W. Negele +3
The electromagnetic, axial and pseudoscalar nucleon to Delta form factors are calculated using dynamical domain wall fermions at a lattice spacing of a = 0.114 fm on a lattice of s…

Delta electromagnetic form factors and quark transverse charge densities from lattice QCD
C. Alexandrou, T. Korzec, G. Koutsou +5
We discuss the techniques to extract the electromagnetic Delta form factors in Lattice QCD. We evaluate these form factors using dynamical fermions with smallest pion mass of about…

Schwinger-Dyson approach for a Lifshitz-type Yukawa model
J. Alexandre, K. Farakos, P. Pasipoularides +1
We consider a 3+1 dimensional field theory at a Lifshitz point for a dynamical critical exponent z=3, with a scalar and a fermion field coupled via a Yukawa interaction. Using the…
