Measurement of the right coupling constants of the weak hadronic neutral current in an antineutrino experiment in a 15-foot bubble chamber

Limitations on the chiral coupling constants of the weak hadronic neutral current are inferred from data (approx.13 000 events) obtained by bombarding the 15-foot Fermilab bubble chamber with a wide-band beam of antineutrinos. The squares of the right constants are found with the help of the left constants from neutrino experiments to be u/sup 2//sub R/ = 0.033 +- 0.017 and d/sup 2//sub R/ = 0.002 +- 0.017.
