Angular Functions with Complex Angular Momenta | | Ya.I. Azimov
; | | Date: |
8 Jul 2013 | | Abstract: | In the study of the amplitudes for many-particle processes, and also for
processes involving particles with spin, the use is made of matrix elements of
the rotation group d^j_{mu
u}(z). In this paper the generalization of the
functions d^j_{mu
u}(z) to arbitrary arguments and indices is studied. At the
same time the functions of the second kind, analogous to Legendre functions of
the second kind, are investigated. The results obtained play an important part
in the introduction of complex angular momenta in many-particle processes.
[Added in 2013: The generalized Legendre functions considered here may be
applied as well to many other problems.] | | Source: | arXiv, 1307.2116 | | Services: | Forum | Review | PDF | Favorites | |
