The Dirac-like nodal excitations were analyzed by investigating the effects of quasiparticle interactions on disorder induced localizations in superconducting high critical temperature cuprates. The exchange by fluctuations of the new order parameter leads to the long-ranged interactions between the quasiparticles at the quantum critical point. The noninteracting random Dirac fermions to the cuprates were analyzed by finding the interaction corrections to the density of states, specific heat, conductivity and phase and energy relaxation rates.
