Description
We report on the search for charged long-lived heavy particles,
predicted by several theories beyond the Standard Model. Such
particles are potentially detectable at the LHC, given either their
anomalous dE/dx loss measurable in the ATLAS Pixel detector, or their
slow motion (beta<1) which can be detected by the Tile Calorimeter,
or even their possible muon-likeness identified by the Muon
Spectrometer. In particular, the Pixel-based search, measuring the
track parameters in the vicinity of the interaction point, is
eagerly sensitive to possible metastable particles, or to changes in
the charge due to interactions with the detector material, which may
make the particles invisible to farther subdetectors. Results of this
search on a data sample corresponding to a large fraction of the
luminosity collected in 2011 are shown.
