Description

We present recent NOMAD measurements on neutrino-induced coherent
production of $\pi^0$, $\rho^+$ and $\rho^0$ mesons. The NOMAD detector
is based upon a low density design (0.1 g/cm^3) offering excellent momentum,
energy and angular resolutions, which are well suited for the measurement
of the coherent production processes.

The new NOMAD measurements are compared with different models for the
coherent scattering off nuclei, in which all nucleons participate in the interaction and the
nucleus recoils intact. These measurements can also provide a test of our
understanding of the weak current at small momentum transfer, namely the PCAC and CVC hypotheses, which are used to model the processes. As a utilitarian application of the measurements, we will discuss the use of coherent $\pi$ and $\rho$ to provide constraints on neutrino fluxes and energy scales.
