Are quarks nonrelativistic in the nucleon?

  • Published:
Il Nuovo Cimento A (1971-1996)

Summary

The ratio of structure functions of deep inelastic electron-nucleon scatteringR=F en2 (x)/F ep2 (x) is studied in QCD in the framework of a formalism with wave functions of a composite particle in the rest system. The analysis of the spin degrees of freedom can be made owing to the rotation invariance of those functions. It is shown that the ratioR may be lower than 3/7 whenX→1 only if we assume that the relative motion of quarks in a nucleon is relativisti. We also discuss to what extent are quarks relativistic.
