Single top quark production is a relatively rare but highly interesting process to study at the Large Hadron Collider (LHC). It provides a direct probe of the electroweak couplings of the top quark, allowing for the exploration of signatures beyond the Standard Model of particle physics, including anomalous couplings, fourth-generation fermions, and new resonances such as W' and charged Higgs bosons. Furthermore, this process offers insights into the structure of protons through parton distribution functions. Various measurements of the top quark's properties — including its spin polarization, mass, and decay width — in single top processes yield valuable information about the impact of different systematic sources, aiding in their control across multiple measurements. In this talk, I will summarize the latest findings related to single top production and discuss the interpretation of the acquired results using essential concepts from modern statistical analyses of LHC collision data.
