Abstract: (arXiv)

We report results of a search for particles with anomalously high ionization in events with a high transverse energy jet and large missing transverse energy in

2.4

fb

^{-1}

of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron

p\bar{p}

collider. Production of such particles (quirks) is expected in scenarios with extra QCD-like {\it SU(N)} sectors, and this study is the first dedicated search for such signatures. We find no evidence of a signal and set a lower mass limit of 107 ~GeV for the mass of a charged quirk with strong dynamics scale

\Lambda

in the range from 10 keV to 1 MeV.
