Detailed Description

Calculation of Decay Significance.

Jet flavour tagging parameter algorithm that calculates the most significant decay length between vertices present in the inputted DecayChain. The algorithm calculates the distance between all consecutive vertices (i.e. with respect to the previous Vertex) in the Jet and the error of the distance. The significance is defined as the distance divided by the error. The algorithm then outputs the significance and the length of the most significant decay length. The class does not have any input parameters.
