TL;DR
This paper explores how new physics, such as heavy neutrino mixing and lepton flavor violation, could be detected in future neutrino factory experiments through modifications in neutrino oscillation patterns, especially in specific channels and baselines.
Contribution
It provides first-order formulas and numerical analysis for detecting new physics effects in neutrino oscillations at future experiments, considering realistic experimental errors.
Findings
Potential for discovering new physics in channels without electron neutrinos.

Enhanced sensitivity with future experimental precision.
Abstract
An extension of the New Standard Model, by introducing a mixing of the low mass ``active'' neutrinos with heavy ones, or by any model with lepton flavor violation, is considered. This leads to non-orthogonal neutrino production and detection states and to modifications of neutrino oscillations in both, vacuum and matter. The possibility of the discovery of such effects in current and future neutrino oscillation experiments is discussed. First order approximation formulas for the flavor transition probabilities in constant density matter, for all experimentally available channels, are given. Numerical calculations of flavor transition probabilities for two sets of New Physics parameters describing a single ``effective'' heavy neutrino state, both satisfying present experimental constraints, have been performed. Two energy ranges and several baselines, assuming both the current…
