Those not familiar with special relativity should consult a textbook on the subject for the physics background necessary to appreciate the significance of Minkowski space and its Lorentz group of invariances. An example of a suitable such book aimed at mathematics students is Woodhouse’s Special Relativity [105].
Most quantum field theory textbooks have some sort of discussion of the Lorentz group and its Lie algebra, although the issue of how complexification works in this case is routinely ignored (recall the comments in section 5.5). Typical examples are Peskin-Schroeder [67], see the beginning of their chapter or chapter II.3 [106] of
