Searches for heavy stable charged particles and other exotic signatures with large ionization at the LHC

The signature of the large ionization is used to search for signals of heavy stable charged particles or other new particles foreseen by models beyond the Standard Model. The related searches in proton-proton collisions at the Large Hadron Collider (LHC) are reviewed. No excess events were found. Results obtained by two LHC experiments ATLAS and CMS with data at a centre-of-mass energy of 7 and 8 TeV collected in 2011 and 2012 are presented in terms of exclusion limits on the mass and the production cross section of hypothetical particles.
