Query: Search for heavy long-lived charged particles in pp collisions at
  sqrt(s) = 7 TeV   The result of a search for heavy long-lived charged particles produced in pp
collisions at sqrt(s) = 7 TeV at the LHC is described. The data sample has been
collected using the CMS detector and corresponds to an integrated luminosity of
5.0 inverse femtobarns. The inner tracking detectors are used to define a
sample of events containing tracks with high momentum and high ionization
energy loss. A second sample of events with high-momentum and high-ionization
tracks satisfying muon identification and long time-of-flight criteria is
analyzed independently. In both cases, the results are consistent with the
expected background estimated from data. The results are used to establish
cross section limits as a function of mass within the context of models with
long-lived gluinos, scalar top quarks and scalar taus. Cross section limits on
hyper-meson particles, containing new elementary long-lived hyper-quarks
predicted by a vector-like confinement model, are also presented. Lower limits
at 95% confidence level on the mass of gluinos (scalar top quarks) are found to
be 1098 (737) GeV. A limit of 928 (626) GeV is set for a gluino (scalar top
quark) that hadronizes into a neutral bound state before reaching the muon
detectors. The lower mass limit for a pair produced scalar tau is found to be
223 GeV. Mass limits for a hyper-kaon are placed at 484, 602, and 747 GeV for
hyper-rho masses of 800, 1200, and 1600 GeV, respectively.
