Abstract

The linear collider experiments are a set of proposals for the next generation of particle collider experiments. These experiments are TeV scale e+e− colliders with an emphasis on precision measurements. The physics programme for the linear collider is designed to complement and extend the work done at the LHC and to develop our understanding of particle physics.

The detector design of these experiments is built around high-granularity Particle Flow Calorimetry that, in contrast to traditional calorimetry, uses the energy measurements for charged particles from the tracking detectors. This can only be realised if calorimetric energy deposits from charged particles can be separated from those of neutral particles. This is made possible with fine granularity calorimeters and sophisticated pattern recognition software, which is provided by the PandoraPFA algorithm. This presentation contains a discussion of the Pandora multi-algorithm approach to Particle Flow Calorimetry and includes the latest results showing the sensitivity of the linear collider experiments to the anomalous gauge couplings ⍺4 and ⍺5.
