Abstract
In this Letter we evaluate the probability rate for the Schwinger production of baryons in an external electric field in the worldline instanton approach in holographic QCD. The new exponentially suppressed processes in a constant electric field involving the composite worldline instantons are suggested which include the non-perturbative decay of a neutron into proton and charged meson and the spontaneous production of p$$\bar {n}$$π– and n$$\bar {p}$$π+ states.
