A bstract We fill up the missing piece in our own re-analysis of long-distance electromagnetic radiative corrections to semileptonic kaon decays by performing a rigorous study K → πμ + ν μ ( γ ) channels. With appropriate experimental and lattice inputs, we achieve precision level 10 − 4 these This is comparable previous analysis πe e this new result, present an updated global extract Standard ...

Background and Objectives: A major challenge that affects the longitudinal studies is the problem of missing data. Missing in the data may result in the loss of part of the information which reduces the accuracy of the estimator and obtain the results will be biased and inaccurate. Therefore, it is necessary to evaluate the missing data mechanism from a longitudinal research and to consider thi...
