The angular and frequency characteristics of the gravitational radiation emitted in collisions of massless particles are studied perturbatively in the context of classical General Relativity for small values of the ratioα ≡ 2rS/bof the Schwarzschild radius over the impact parameter. The particles are ...
We shall study in this chapter the internal space-time symmetries of massless particles. As was noted in Chapter III, the little group for massless particles is locally isomorphic to the group of Euclidean transformations on a two- dimensional plane which is often called E(2). Therefore, the ...
In particle physics, massless particles are those that literally have an invariable mass of zero regardless of their energy levels. Gluons are one example of a massless particle, and they're the fundamental particles that act as the force carriers of the strong nuclear charge. ...
particles of helicity ±1. It is clear from the indecomposability of S under P that direct integral decompositions could not have achieved this reduction. We now turn to the (‘second’) quantization of S (from an algebraic point of view, the object that is quantized is actually the Poisson...
New simulations of these events show hot neutrinos -- tiny, essentially massless particles that rarely interact with other matter -- that are created during the collision can be briefly trapped at these interfaces and remain out of equilibrium with the cold cores of the merging stars for 2 to ...

A sourceof the divergences in QED is proposed, and a theory in which the Lamb shift andelectron's anomalous magnetic moment are calculated free of divergences isreviewed. It is shown that Dirac's equation for a relativistic electron can beinferred from a Lorentz invariant having the form of ...
