Abstract
In this paper we present a technique to reconstruct the
scaling variables defining ep deep inelastic scattering by
performing a kinematic fit. This reconstruction technique makes use
of the full potential of the data collected. It is based on Bayes'
Theorem and involves the use of informative priors. The kinematic
fit method has been tested using a simulated sample of ep neutral
current events at a center of mass energy of 318 GeV with
Q
2 > 400 GeV2. In addition to the scaling variables, this
method is able to estimate the energy of possible initial state
radiation (Eγ
) which otherwise goes undetected. A better
resolution than standard electron and double angle techniques in the
reconstruction of scaling variables is achieved using a kinematic
fit.
