Boron 12 in Double Chooz — Dennis Dietrich, Josef Jochum, Tobias Lachenmaier, Markus Röhling, and •Lee Stokes — Physikalisches Institut, Universität Tübingen

The Double Chooz reactor neutrino experiment is designed with the intention of measuring the disappearance of ν_e and therefore the third mixing angle Θ₁₃.
The far detector has been taking data since April 2011 and the near detector is currently under construction. With the arrival of the near detector comes a lesser overburden of roughly 120 m.w.e, giving rise to a higher muon rate in comparison to the far detector and consequently an increase in the amount of potential background in the form of cosmogenically created isotopes.
¹²B is one of these such isotopes and needs to be better understood with the possibility of constraining the ⁹Li background. In this talk I give an overview of what has been achieved so far.
