Departmental Colloquium: Dr. Victor Bazterra
“Single top quark production at D0”
The top quark plays a special role within the Standard Model description of the fundamental interactions. Within this model, top quarks can be produced at hadron colliders in pairs via the strong interaction, or singly via the electroweak interaction. Pair production was observed for the first time by the CDF and D0 collaborations in 1995 at the Tevatron collider. However, it took another 14 years and 50 times more data for the observation of the single top quark production.
In this talk I will describe the challenges of studying single top production at the Tevatron and I will introduce some of the multivariate and statistical analysis techniques required to make this study possible. I will concentrate on the most recent results that allow us to learn more about the details of the production and also to measure some top quark properties such as its lifetime. I will also show how the analysis can be used to search for physics beyond the Standard Model.
