Counting of generalized polarizabilities

Research output: Contribution to journalArticle

1 Scopus citations


We demonstrate a concise method to enumerate the number of generalized polarizabilities - quantities characterizing the independent observables in singly virtual Compton scattering - for a target particle of arbitrary spin s. By using crossing symmetry and JPC conservation, we show that this number is (10s+1+δs,0).
