On a General Spin Dirac Equation
نویسنده
چکیده
In its bare and natural form, the Dirac Equation describes only spin-1/2 particles. The main purpose of this reading is to make a valid and justified mathematical modification to the Dirac Equation so that it describes any spin particle. We show that this mathematical modification is consistent with the Special Theory of Relativity (STR). We believe that the fact that this modification is consistent with the STR gives the present effort some physical justification that warrants further investigations. From the vantage point of unity, simplicity and beauty, it is natural to wonder why should there exist different equations to describe particles of different spins? For example, the Klein-Gordon equation describes spin-0 particles, while the Dirac Equation describes spin-1/2, and the Rarita-Schwinger Equation describes spin-3/2. Does it mean we have to look for another equation to describe spin-2 particles, and then spin-5/2 particles etc? This does not look beautiful, simple, or at the very least suggest a Unification of the Natural Laws. Beauty of a theory is not a physical principle but, one thing is clear to the searching mind – i.e., a theory that possesses beauty, appeals to the mind, and is (posteriori) bound to have something to do with physical reality if it naturally submits itself to the test of experience. The effort of the present reading is to make the attempt to find this equation.

Global Solutions of Einstein–dirac Equation
The conformal space M was introduced by Dirac in 1936. It is an algebraic manifold with a spin structure and possesses naturally an invariant Lorentz metric. By carefully studying the birational transformations of M, we obtain explicitly the transition functions of the spin bundle over M. Since the transition functions are closely related to the propagation in physics, we get a kind of solution...
متن کاملDirac Equation in Kerr Geometry
We are familiar with Dirac equation in flat space by which we can investigate the behaviour of half-integral spin particle. With the introduction of general relativistic effects the form of the Dirac equation will be modified. For the cases of different background geometry like Kerr, Schwarzschild etc. the corresponding form of the Dirac equation as well as the solution will be different. In 19...

Hybrid Dirac fields are fields that are general superpositions of the annihilation and creation parts of four Dirac spin 1/2 fields, ψ (±) (x; ±m), whose annihilation and creation parts obey the Dirac equation with mass m and mass −m. We discuss a specific case of such fields, which has been called " homeotic. " We show for this case, as is true in general for hybrid Dirac fields (except the or...

The main objective of this paper is to clarify the ontology of DiracHestenes spinor fields (DHSF ) and its relationship with sum of even multivector fields, on a general Riemann-Cartan spacetime M=(M, g,∇, τg, ↑) admitting a spin structure and to give a mathematically rigorous derivation of the so called Dirac-Hestenes equation (DHE ) when M is a Lorentzian spacetime. To this aim we introduce t...
