Two models in which the new heavy particle is a color singlet or a color triplet are considered, decaying, respectively, to (t)over-barq or tq, leading to a resonance within the t(t)over-bar + jets signature. The full 2011 ATLAS pp collision data set from the LHC (4.7 fb(-1)) is used to search for t(t)over-bar events produced in association with jets, in which one of the W bosons from the top quarks decays leptonically and the other decays hadronically. The data are consistent with the Standard Model expectation, and a new particle with mass below 430 Gev for both W{\textquoteright} boson and color triplet models is excluded at 95{\%} confidence level, assuming unit right-handed coupling.", optnote="WOS:000311547400001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=1244), last updated on Tue, 25 Dec 2012 19:08:09 +0000", issn="1550-7998", doi="10.1103/PhysRevD.86.091103", opturl="http://arxiv.org/abs/1209.6593", opturl="https://doi.org/10.1103/PhysRevD.86.091103", archivePrefix="arXiv", eprint="1209.6593", language="English" }
