## Abstract

Properties of the noise-driven escape kinetics are mainly determined by the stochastic component of the system dynamics. Nevertheless, the escape dynamics is also sensitive to deterministic forces. Here, we are exploring properties of the overdamped drifted escape from finite intervals under the action of symmetric $\\alpha$-stable noises. We show that the properly rescaled mean first passage time follows the universal pattern as a function of the generalized P\\'ecklet number, which can be used to efficiently discriminate between domains where drift or random force dominate. Stochastic driving of the $\\alpha$-stable type is capable of diminishing the significance of the drift in the regime when the drift prevails.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
