Resumen:
A search is presented for heavy-quark pair production
(QQbar) under the decay hypothesis QQbar to WqWq with q = u,d,c,s,b. The
search is performed with 1.04 fb^-1 of integrated luminosity from pp
collisions at sqrt(s) = 7 TeV collected by the ATLAS detector at the
CERN LHC. Dilepton final states are selected, requiring large missing
transverse momentum and at least two jets. Mass reconstruction of heavy
quark candidates is performed by assuming that the W boson decay
products are nearly collinear. The data are in agreement with Standard
Model expectations/ a heavy quark with mass less than 350 GeV is
excluded at 95% confidence level.
