Neutralino Decay Rates with Explicit R-parity Violation

We compute the neutralino decay rate in the minimal supersymmetric standard model with the addition of explicit R-parity violation. We include the complete squark and slepton mixing matrices, previously neglected, and we improve and correct published formulas. These decays are relevant to accelerator and non-accelerator searches for R-parity violation, and are especially interesting in light of the reported high Q^2 anomaly at HERA.
