Orbital Angular Momentum in the Nucleon
Gerald T. Garvey
TL;DR
This paper explores how the flavor asymmetry in the nucleon’s sea quarks is directly related to the orbital angular momentum generated by nucleon fluctuations into baryon-pion states, emphasizing angular momentum conservation.
Contribution
It demonstrates that the orbital angular momentum in the nucleon equals the measured flavor asymmetry, linking nucleon fluctuations to angular momentum conservation.
Findings
The measured ar-ar asymmetry is 0.147 b1 0.027.
Orbital angular momentum from nucleon fluctuations equals the flavor asymmetry.
Nucleon fluctuations into baryon plus pion account for the observed asymmetry.
Abstract
Analysis of the measured value of the integrated \bar{d}-\bar{u} asymmetry (Ifas = 0.147+-0.027) in the nucleon show it to arise from nucleon fluctuations into baryon plus pion. Requiring angular momentum conservation in these fluctuations shows the associated orbital angular momentum is equal to the value of the flavor asymmetry.
