Sumario:The Standard Model has withstood precision tests for the last 30 years and offers a plausible theory of particles and there interactions at the TeV scale. The one element which has not been directly explored experimentally is the explanation of the origin of mass and electroweak symmetry breaking. Further, there are well known theoretical issues that are not completely satisfactory in the model (the hierarchy problem, triviality, naturalness, amongst others). Recently a recurrence of "Little Higgs" models which offer a solution to the the problem of electroweak symmetry breaking without the known problems have been proposed. These theories offer a rich phenomenology including an extended Higgs sector, new gauge bosons, and new fermions. All of these can be explored by the Atlas and CMS detectors at the LHC. This talk explores the initial studies carried out by the two collaborations which estimate the sensitivity to the variety of new particles that are predicted by this class of theories.
