Kalman Filter Track Fits and Track Breakpoint Analysis
We give an overview of track fitting using the Kalman filter method in the NOMAD detector at CERN, and emphasize how the wealth of by-product information can be used to analyze track breakpoints (discontinuities in track parameters caused by scattering, decay, etc.). After reviewing how this information has been previously exploited by others, we describe extensions which add power to breakpoin...
متن کاملFast SIMDized Kalman filter based track fit
Modern high energy physics experiments have to process terabytes of input data produced in particle collisions. The core of the data reconstruction in high energy physics is the Kalman lter. Therefore, the speed of Kalman lter based algorithms is of crucial importance in on-line data processing. This is especially true for the combinatorial track nding stage where the Kalman lter based track t ...
متن کاملCovariance Matrices for Track Fitting with the Kalman Filter
We present a simple and intuitive derivation of the track parameter covariance matrix due to multiple Coulomb scattering for use in track fitting with the Kalman filter. We derive all the covariance matrix elements for two experimentally relevant track parameterizations (i.e. x and y slopes and intercepts, and direction cosines and intercepts) in the presence of thin scatterers and absence of m...
متن کاملPorting a Kalman filter based track fit to NVIDIA CUDA
Finding particle trajectories is usually the most time consuming part of modern experiments in high energy physics. In many present experiments with high track densities and complicated event topologies a Kalman filter based track fit is used already at this combinatorial part of the event reconstruction. Therefore speed of the track fitting algorithm becomes very important for the total proces...
متن کاملThe Kalman Filter Technique Applied to Track Fitting in Glast
Using the iterative property of the Kalman Filter technique an estimate of the track parameter resolution for the case of the GLAST design (straight line tracks and periodic hits measurements) has been computed at the vertex position.
