Application of vertex and mass constraints in track-based alignment

Christophe Salzmann, Louis Nicolas, Géraldine Conti, Vincent Fave, Olivier Schneider, Frédéric Guillaume Dupertuis, Gerhard Raven, Matthew Needham, Maurizio Martinelli

The software alignment of planar tracking detectors using samples of charged particle trajectories may lead to global detector distortions that affect vertex and momentum resolution. We present an alignment procedure that constrains such distortions by mak ...
