    Separating single top quark signal from background using distribution mixture model

  • Original language description

    A very common situation in experimental high energy physics is signal which cannot be separated from background by use of any cut. Application of the distribution mixtures, a modified iterative Expectation-Maximization algorithm for weighted data, and taking advantage of Bayesian statistics represents promising multivariate technique in this area. The paper presents statistical theory, computational aspects of the algorithm, and work- ing results of signal from background separation obtained by application of the proposed method to a single top analysis with the full D0 Run II dataset of 9.7 fb-1 of integrated luminosity with corresponding signal and background Monte Carlo.
