Decay Chain Fitting with a Kalman Filter
arXiv:physics/0503191 · doi:10.1016/j.nima.2005.06.078
Abstract
We present a method to perform a least squares fit of a decay chain involving multiple decay vertices. Our technique allows for the simultaneous extraction of decay time, position and momentum parameters and their uncertainties and correlations for all particles in a decay chain.
