Observation of Single Top Quark Production

Understand

The field of experimental particle physics has become more sophisticated over time, as fewer, larger experimental collaborations search for small signals in samples with large components of background.

• The search for and the observation of electroweak single top quark production by the CDF and DZero collaborations at Fermilab's Tevatron collider are an example of an elaborate effort to measure the rate of a very rare process in the presence of large backgrounds and to learn about the properties of the top quark's weak interaction.
• We present here the techniques used to make this groundbreaking measurement and the interpretation of the results in the context of the Standard Model.
