The difference of the cross sections for deep inelastic scattering of muons with average momenta 21 GeV/c with right and left helicity at large angles, i.e., with large momentum transfer, has been measured. No statistically-significant dependence of cross sections on the longitudinal polarization of muons has been found, i.e. no parity-nonconservation effects in deep inelastic μN interaction have been observed. The magnitude of the cross-section asymmetry R = [〈σ R 〉 − 〈σ L 〉] [〈σ R 〉+ + 〈σ L 〉] may be represented as R = β〈Q2〉 = (− 4 ± 6) × 10−3 〈Q2, (GeV/c)2〉. The limitations Go(μ) = (+ 6 ± 10)G have been obtained for the constant Go(μ) of vector-axial interaction ( G o (μ) 2 ) [ μ γα(1 + γ 5 )μ] J α o (hadron, V-A). |
