# $b\bar b u\bar d$ four-quark systems in the Born-Oppenheimer approximation: prospects and challenges

## Speakers

• Ms. Antje PETERS

## Content

We summarize previous work on $\bar b \bar b u d$ four-quark systems in the Born-Oppenheimer approximation and discuss first steps towards an extension to the theoretically more challenging $b \bar b u \bar d$ system. Strategies to identify a possibly existing $b \bar b u \bar d$ bound state are discussed und first numerical results are presented.
