Description
In this talk I will focus on the charged Higgs particles in the context of the LHC discovery physics. I will motivate them through low energy effects (rho-parameter, neutrino masses,...). A link between TeV scale effects and low energy physics (e.g. muon decay, neutrinoless double beta decay) will be shown. Production and decays of singly and doubly charged scalars will be discussed in more details in the framework of one of the simplest GUT models based on the left-right gauge symmetry. Status of those models will be presented. Beyond the Standard Model, spontaneous symmetry breaking effects bring relations among heavy particles' masses, thus possible LHC discovery signals connected with heavy gauge bosons and heavy neutrino particles will be also analyzed.
