The data are compared with predictions from perturbative quantum chromodynamics at next-to-next-to-leading order, including electroweak corrections.The distributions are used to search for proposed signatures of quark compositeness, extra spatial dimensions, quantum black holes, axion-like particles, and anomalous gluon couplings.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.167852.v1/t1","@type":"Dataset","description":"Normalized CHI = exp(|Y1-Y2|) distributions (1/N)*D(N)/DCHI in 2.4 &lt; M(JJ) &lt; 3.0 TeV with |Y1+Y2|/2&lt; 1.1.
