- I have been involved in all searches for exotic baryons at LHCb since 2014, developing analysis techniques and leading analyses. I led the development of detailed particle identification techniques, including the construction of the RICH detectors and the calibration package PIDCalib that defines the particle identification of all tracks from these decays. This paper is the first discovery (greater than 6 sigma) of a five-quark state (uudc c-bar) known as a pentaquark, a previously unobserved quark configuration. This paper was acknowledged as the most significant CERN discovery of 2015 and one of the scientific breakthroughs of 2015.
