N=4 superconformal mechanics in the pp-wave limit

We constructed the pp-wave limit of N=4 superconformal mechanics with the off-shell $(\mathbf{3},\mathbf{4},\mathbf{1})$ multiplet. We present the superfield and the component actions which exhibit the interesting property that the interaction parts are completely fixed by the symmetry. We also explicitly demonstrate that the passing to the pp-wave limit can be achieved by keeping at most quadratic nonlinearities in the action of (super)conformal mechanics.
