In this work the determination of low-energy bound states in quantum chromodynamics is
recast so that it is linked to a weak-coupling problem. This allows one to approach the …

The first part of this paper extends the Doplicher–Haag–Roberts theory of superselection
sectors to quantum field theory on arbitrary globally hyperbolic spacetimes. The statistics of …

Applications of relativistic light front dynamics to computing the nucleonic and mesonic
components of nuclear wave functions are reviewed. In this approach the fields are …

We both review and augment the lightcone conformal truncation (LCT) method. LCT is a
Hamiltonian truncation method for calculating dynamical quantities in QFT in infinite volume …

The focus of this review of null-plane dynamics is the fundamental principle of quantum
theory that states must form a linear manifold with a positive scalar product. The intent is to …

We study twistorial mechanics of particles and super-particles in six dimensions. To this end
we formulate (in a general division algebra framework) a twistor theory in D= 6 based on …

A bstract We present a new framework for studying conformal field theories deformed by one
or more relevant operators. The original CFT is described in infinite volume using a basis of …

A bstract We consider Lorentzian CFT Wightman functions in momentum space. In
particular, we derive a set of reference formulas for computing two-and three-point functions …

A bstract We use Lightcone Conformal Truncation (LCT)—a version of Hamiltonian
truncation—to study the nonperturbative, real-time dynamics of ϕ 4-theory in 2+ 1 …

A bstract We present a prescription for an effective lightcone (LC) Hamiltonian that includes
the effects of zero modes, focusing on the case of Conformal Field Theories (CFTs) …
