We studied the model of the SU(N) gauge theory coupled to a Majorana fermion in adjoint representation. In order to calculate the spectrum we used light-cone quantization in 1+1 dimensions and discrete light-cone quantization, in which the mass-squared quantum operator can be described in terms of finite matrices that can be diagonalized numerically.CC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/Cromodinâmica quânticaEspectro de hádronsQuantização no cone de luzTeoria não-perturbativaQuantum chromodynamicsHadron spectroscopyLight-cone quantizationNon-perturbative theorybachelorThesis
