A new method of function minimization is developed and a new code (called FUMIVI) is created. Its main features are: i) regular functions of arbitrary structure can be minimized, ii) when minimizing χ 2 -like functions or functionals of a more gener

The structure of traditional data processing systems looks approximately like this: space coordinates of events C i are searched, parameters X j (angles, momenta and so on) are estimated together with their covariance matrix and then kinematical anal

The problem of minimization of the functional χ 2 = ∑ i, j nf, nf [C i (X)−C m i ]G ij [C j (X)−C m j ]; i, j=1… nf , with the constraints ƒ λ (X)=0; λ=1…nc , is considered. Here: X is the vector of the parameters to be estimated, Ci(X)

A method for calculation of the momentum of a charged particle in magnetic spectrometers in high energy experiments with fixed targets is proposed. It is compared with the widely used method of Lechanoine, Martin and Wind [Nucl. Instr. and Meth. 69 (

We have observed 150 double charge exchange events, π − + 7 Li → π + + anything , at an incident π − lab kinetic energy of 102 MeV. The π + were recorded in an emulsion stack at 30° to the incident π − beam. No significant peak due to t

The parameter estimation method and the goodness-of-fit test generalizing the well-known χ 2 are proposed. The expression for a covariance matrix is obtained. The asymptotic efficiency of the proposed method is proved.
