Some remarks related to on-shell methods for amplitudes
I will discuss the group-theoretical approach to the amplitudes, employing spinor-helicity variables concentrating on the example of the description of massive spinning particles in four dimensions to illustrate the main concept. The generalizations to higher dimensions will be discussed briefly. This talk is based on earlier work [JHEP 1608 (2016) 040] with E. Conde and E. Joung and an ongoing work with E. Joung and M. Mojaza.
