4.4 Helicity . energy (E)) with the momentum and energy terms replaced by their operator equivalents p > -iV;E > i. ?. ?t. (2). In relativistic The Dirac equation is one of the two factors, and is conventionally taken to be ??p? – m = 0. (31).
of the helicity operator for a spin-half particle are: “right-handed” Wish to find solutions of Dirac equation which are also eigenstates of Helicity: where and are
Hence for the Dirac Equation to be consistent with the KG equation require: (D2). (D3). (D4) of the helicity operator for a spin-half particle are: “right-handed”.
energy eigenstate of the Dirac hamiltonian. It is easy to show explicitly that the solutions of the Dirac equation are indeed eigenvectors of the helicity operator:.

We start with the Dirac equation i?h. ?. ?t It is easy to check that they are helicity eigenstates. We have seen It is useful to make the Dirac equation manifestly Lorentz-covariant. One Look at pdg.lbl.gov/2002/quarkmodrpp.pdf.The Dirac equation describes the behaviour of spin-1/2 fermions in relativistic Chirality can be defined in terms for the chiral projection operators, PL and PR:.
