A 95{\%} confidence level upper limit on the cross section times branching ratio of nonresonant production is set at 2.2 pb, while the expected limit is 1.0 pb. The difference derives from a modest excess of events, corresponding to 2.4 standard deviations from the background-only hypothesis. The limit observed in the search for a narrow X -> hh resonance ranges between 0.7 and 3.5 pb as a function of the resonance mass.", optnote="WOS:000350210600004", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=2161), last updated on Thu, 09 Apr 2015 15:52:52 +0000", issn="0031-9007", doi="10.1103/PhysRevLett.114.081802", opturl="http://arxiv.org/abs/1406.5053", opturl="https://doi.org/10.1103/PhysRevLett.114.081802", archivePrefix="arXiv", eprint="1406.5053", language="English" }
