TL;DR: In this article, the authors used the ZEUS detector to study diffractive DIS and its diffractive component at HERA with an integrated luminosity of 4.2 pb −1, showing that the ratio of diffractive to total cross section is constant as a function of energy W (37-245 GeV), photon virtuality Q2 (2.2-80 GeV2) and mass M X (0.28-35 GeV).

TL;DR: In this article, angular correlations between the three jet axes were analyzed to determine the spin of the gluon in the reaction e+e- → qqg, and it was shown that scalar gluons are disfavoured by 3.8 standard deviations, corresponding to a confidence level of about 10-4.
