Pinched Gluon Vertex Operator in Super Worldline Formalism
We reformulate, using super worldline formalism, the pinched gluon vertex operator proposed by Strassler. The pinched vertex operator turns out to be the product of two gluon vertex operators with the insertion of δ-function which makes the super distances between them zero. Thus the pinch procedures turn out to be nothing but the insertions of δ-function. Applying our formulation to two-loop d...
متن کاملWorld-Line Formalism: Non-Perturbative Applications
This review addresses the impact on various physical observables which is produced by confinement of virtual quarks and gluons at the level of the one-loop QCD diagrams. These observables include the quark condensate for various heavy flavors, the Yang-Mills running coupling with an infra-red stable fixed point, and the correlation lengths of the stochastic Yang-Mills fields. Other non-perturba...
متن کامل1 PI Green functions in the world - line formalism
We demonstrate, at the one-loop level, how the theory-independent part of proper N-point Green functions at finite temperature and chemical potential can be formulated in the world-line formalism, where φ 3 theory, photon scattering, effective potential in a constant magnetic field, π 0 → 2γ decay are all described in a unified way. We then derive various useful formulae and check their consist...
متن کاملResummed effective action in the world-line formalism
Using the world-line method we resum the scalar one-loop effective action. This is based on an exact expression for the one-loop action obtained for a background potential and a Taylor expansion of the potential up to quadratic order in x-space. We thus reproduce results of Masso and Rota very economically. An alternative resummation scheme is suggested using “center of mass” based loops which ...
متن کاملthe tragedy of modern man in arthur millers world
what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...
