Confinement and the Transverse Lattice∗
Deep inelastic lepton-hadron scattering has played a fundamental role in the investigation of hadron structure. For example, the discovery of Bjorken scaling confirmed the existence of point-like charged objects inside the nucleon (quarks). Besides such fundamental discoveries, deep inelastic scattering (DIS) revealed surprising and interesting details about the structure of nucleons and nuclei...
متن کاملGlueballs on a transverse lattice
Accurate non-perturbative calculations of glueballs are performed using light-front quantised SU(N) gauge theory, to leading order of the 1/N expansion. Based on early work of Bardeen and Pearson, disordered gauge-covariant link variables M on a coarse transverse lattice are used to approximate the physical gauge degrees of freedom. Simple energetics imply that, at lattice spacings of order the...
متن کاملQcd on a Transverse Lattice
The transverse lattice 1 is an attempt to combine advantages of the light-front (LF) and lattice formulations of QCD. In this approach to QCD the time and one space direction (say x) are kept continuous, while the two ‘transverse’ directions x⊥ ≡ (x , x) are discretized. Keeping the time and x directions continuous has the advantage of preserving manifest boost invariance for boosts in the x di...
متن کاملMesons on a transverse lattice
The meson eigenstates of the light-cone Hamiltonian in a coarse transverse lattice gauge theory are investigated. Building upon previous work in pure gauge theory, the Hamiltonian and its Fock space are expanded in powers of dynamical fields. In the leading approximation, the couplings appearing in the Hamiltonian are renormalised by demanding restoration of space-time symmetries broken by the ...
متن کاملTransverse Lattice QCD in 2+1 Dimensions
Based on an idea due to Bardeen and Pearson, we formulate the light-front Hamiltonian problem for SU(N) Yang-Mills theory in (2+1)-dimensions using two continuous space-time dimensions and the remaining space dimension discretised on a lattice. We employ analytic and numerical methods to investigate the continuum limit and the glueball spectrum for N = ∞. In this limit, EguchiKawai reduction to...
