Regularising experimental correlations in LHC data: theory and application to a global analysis of parton distributions
Abstract We show how an inaccurate determination of experimental uncertainty correlations in high-precision LHC measurements may undermine the reliability of the associated $$\chi ^2$$ χ 2 . We formulate the problem rigorously, and devise a regularisation procedure that increases the stability of th...
