Track parameter propagation through the application of a new adaptive Runge-Kutta-Nyström method in the ATLAS experiment
Lund, Espen; Bugge, Lars; Gavrilenko, Igor; Strandlie, Are (Journal article; Peer reviewed, 2009)In this paper we study several fixed step and adaptive Runge-Kutta methods suitable for transporting track parameters through an inhomogeneous magnetic field. Moreover, we present a new adaptive Runge-Kutta-Nyström method ... -
Transport of covariance matrices in the inhomogeneous magnetic field of the ATLAS experiment by the application of a semi-analytical method
Lund, Espen; Bugge, Lars; Gavrilenko, Igor; Strandlie, Are (Journal article; Peer reviewed, 2009)In this paper we study the transport of track parameter covariance matrices - the so-called error propagation - in the inhomogeneous magnetic field of the ATLAS experiment. The Jacobian elements are transported in parallel ...
