Covariant Variable Front Quark Model
Abstract
We study the implications of Lorentz symmetry for hadronic structure by formulating a manifestly covariant constituent quark model and find full covariance for any Lorentz transformation requires utilizing a variable quantization surface. Even though time-reversal invariance mandates a unique orientation for the surface's direction, we investigated alternative choices and find small numerical sensitivity to different directions. We also calculate the static properties of the low lying pseudoscalar mesons and compare results with existing noncovariant calculations. We conclude that there is a little sensitivity of the calculated observables to the choice of the formalism, provided relativity is properly implemented.
