A bstract We consider the off-shell momentum space Green’s functions in closed superstring field theory. Recently [1], — after explicitly removing contributions of massless states have been shown to be analytic on a domain (to called LES domain) complex external momenta variables. Analyticity local QFTs without primitive is well-known result. Using Lorentz transformations and Bochner’s theorem ...

Using the helicity amplitudes formalism, we study deeply virtual exclusive electron photoproduction off an unpolarized nucleon target, $ep\ensuremath{\rightarrow}{e}^{\ensuremath{'}}{p}^{\ensuremath{'}}\ensuremath{\gamma}$, through a range of kinematics both in fixed target setting with initial energies 6, 11, and 24 GeV for ion collider. We reformulate cross section bringing to forefront defin...
