Electromagnetic form factor of the pion in the space- and time-like regions within the front-form dynamics
(2004-02-12)
The pion electromagnetic form factor is calculated in the space- and time-like regions from -10 (GeV/c)2 up to 10 (GeV/c)2, within a front-form model. The dressed photon vertex where a photon decays in a quark-antiquark ...
Ideas of four-fermion operators in electromagnetic form factor calculations
(2013-05-07)
Four-fermion operators have been used in the past to link the quark-exchange processes in the interaction of hadrons with the effective meson-exchange amplitudes. In this paper, we apply the similar idea of a Fierz ...
