Application of liquid-core fibres for a radiation-hard vertex detector

We propose a novel vertex detector based on liquid-core fibers which can reach and exceed the performance of the current HERA-B vertex detector, while offering even greater resistance to aging due to radiation effects. This radiation resistance would provide an improved vertex resolution by allowing one to place the detector elements closer to the particle beam, and thus provide an improvement in the measurement of Bs, mixing while extending the accessible region of xs.
