No excesses over the Standard Model predictions are observed. Bayesian lower limits at the 95% credibility level are placed on the mass of a Z' boson, the mass of a supersymmetric tau-sneutrino, and on the threshold mass for quantum black-hole production. For the Z' and sneutrino models, upper cross-section limits are converted to upper limits on couplings, which are compared with similar limits from low-energy experiments and which are more stringent for the e tau and mu tau modes.eninfo:eu-repo/semantics/openAccessPROTON-PROTON COLLISIONSPLUS PLUSDECAYHIERARCHYPHYSICSArticle2-s2.0-8505812109210.1103/PhysRevD.98.092008Q1WOS:000450140200001
