Hi! I was taught that the dirac matrices are AT LEAST 4x4 matrices, so that means that I can find also matrices of higher dimensions. The question is: what do these higherdimensionmatrices represent? Are they just mathematical stuff or have they got a physical meaning? I ask that because in every textbook and in every course I used only the 4x4 matrices...
Thanks
