Updated Standard Model Prediction for $K\to \pi \nu \bar{\nu }$ and ${\epsilon }_K$

Joachim Brod, Martin Gorbahn, Emmanuel Stamou

The rare $K\to \pi \nu \bar{\nu }$ decay modes and the parameter ${\epsilon }_K$ that measures CP violation in Kaon mixing are sensitive probes of physics beyond the standard model. In this article we…
