... have eliminated T from the very beginning, so that we didn’t have to think about it at all! The above example is somewhat simplistic, as it only contains two objects moving in one dimension and so it is not very difficult to solve. Imagine instead a system of 10 objects moving in three dimensions, w ...

Hadronization of Quark Theories
Hadronization of Quark Theories

... At present it appears that a Lagrangian field theory of the Yang-Mills type is the correct fundamental theory of elementary particles. The gluon fields form flux tubes between quarks and antiquarks which have a fixed diameter of the order of the Compton wavelength of the pion. Since the field energy ...

... group of the field theory is SU (N ) when the flux through S 5 is N . In the case of large N and large effective coupling, Maldacena’s conjecture relates the corresponding field theory and the classical supergravity. Finite N effects contain important information about the qualitative novelties of q ...

... We believe it is a Higgs boson, a fundamental spin-0 particle, and its discovery has far-reaching consequences on our thinking about Nature. For the first time we have detected a fundamental scalar field! It is possible that fundamental scalar fields are responsible for the inflation in the early un ...

Propagator

In quantum mechanics and quantum field theory, the propagator gives the probability amplitude for a particle to travel from one place to another in a given time, or to travel with a certain energy and momentum. In Feynman diagrams, which calculate the rate of collisions in quantum field theory, virtual particles contribute their propagator to the rate of the scattering event described by the diagram. They also can be viewed as the inverse of the wave operator appropriate to the particle, and are therefore often called Green's functions.
