The result obtained here (top red circle) is compared with those derived in midrapidity measurements of double-quarkonium and electroweak-boson-plus-quarkonium production22,24,25,57,58,59,60 (blue symbols), as well as in final states with jets19,51,52,62, γ + jets53,54,55,56, W + jets13,14 and same-sign W bosons18 (black symbols). The arrows indicate lower (or upper) limits at 95% (68%) confidence level. For the experimental results marked with a star, more recent theoretical reinterpretations based on more accurate calculations of the corresponding SPS cross-section are plotted. The original experimental results can be found in ref. 23 (CMS), ref. 26 (D0) and refs. 50,63 (ATLAS).
