Pattern Recognition Algorithm for the High Angle TPCs of the T2K Near Detector Upgrade — Philip Hamacher-Baumann, •Paula Nehm, Paolina Noll, Thomas Radermacher, Stefan Roth, David Smyczek, and Nick Thamm — RWTH Aachen University - Physics Institute III B, Aachen, Germany

The T2K near detector upgrade includes the addition of two High Angle Time projection chambers (HATs). They will increase the selection efficiency of leptons for scattering angles larger than ca. 40 degrees by achieving a full polar angle coverage for muons produced in CC events. For these HATs the reconstruction algorithm needs to be reworked. As a first step the pattern recognition algorithm of the already installed time projection chambers of the T2K near detector has been adapted for the new HATs. This as well as the readjustment of the parameters of the algorithm to the new geometry will be presented.
