Diffractive Production of Vector Mesons in High-Energy Neutrino Interactions

Results for diffractive production of vector mesons in high-energy neutrino-proton interactions are presented. Diffractive production of ${\rho }^{+}$ is observed with a cross section of (8 ± 3) × ${10}^{-40\mathrm{}}$ ${\mathrm{cm}}^2$ in agreement with recent theoretical predictions. Upper limits for ${A_1}^{+}$ and $B^{+}$ production are presented. The limit for $B^{+}$ production gives a new limit on the contribution of weak second-class currents.
