Contribution

It introduces a covariant framework to analyze deep inelastic scattering kinematics, emphasizing the role of symmetry constraints on quark momenta.

Findings

Constraints on quark intrinsic momenta derived from symmetry considerations

Comparison with experimental data supports the theoretical constraints

Highlights importance of Lorentz invariance in scattering kinematics

Abstract

We study the kinematics of deep inelastic scattering corresponding to the rotationally symmetric distribution of quark momenta in the nucleon rest frame. It is shown that rotational symmetry together with Lorentz invariance can in leading order impose constraints on the quark intrinsic momenta. Obtained constraints are discussed and compared with the available experimental data.
