We explore the convergence of the light-front coupled-cluster (LFCC) method in the context of two-dimensional quenched scalar Yukawa theory. This theory is simple enough for higher-order LFCC calculations to be relatively straightforward. The quenching is to maintain stability; the spectrum of the full theory with pair creation and annihilation is unbounded from below. The basic interaction...

In this presentation we will discuss some interesting properties of the off-shell scattering amplitudes in the framework of the light-front perturbation theory. It is shown that certain recursion relation between tree level off-shell amplitudes in this formalism actually resums whole classes of graphs into a Wilson line. More precisely, we demonstrate a correspondence between the light-front...

The MHV Lagrangian is the Yang-Mills Lagrangian quantized on the light cone, where the two transverse gluonic degrees of freedom have been canonically transformed to a set of new fields, in which the vertices become a series of the maximally helicity violating (MHV) amplitudes continued off-shell. The usage of the MHV vertices to construct amplitudes is also known as the...

The expectation value of the quantum energy-momentum tensor (EMT) for an unpolarized proton target in the Breit frame can be matched with an anisotropic perfect fluid EMT. This matching offers the possibility of interpreting the EMT form factors in terms of the internal energy and transverse/radial pressure inside an unpolarized proton target. The generalization of this result to a more...

The advent of approaches based on the Euclidean space for studying hadron observables, such as lattice QCD and Schwinger-Dyson equations, has been remarkable and responsible to produce important understanding on the non-perturbative dynamical regime. However, the quantum field theory formulation in Minkowski space has subtle and essential signatures as, e.g., the ones related to...
