Web9 de abr. de 2024 · 8. 2. I have this Lagrangian for a free massless left Weyl spinor, so it’s just the kinetic term, that can be written embedding the field into a larger Dirac spinor and then taking the left projector in this way: Srednicki says that the momentum space propagator can be immediately read off as. I don't understand how this can be … Web27 de abr. de 2016 · Several powerful techniques for evaluating massless scalar Feynman diagrams are developed, viz: the solution of recurrence relations to evaluate diagrams with arbitrary numbers of loops in...

WebIn Ref. massless scalar field theory was constructed in Snyder space while still maintaining continuous momentum space variables, an approach very different from that of prior … WebCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): In this paper we investigate massless scalar field theory on non-degenerate algebraic curves. The propagator is written in terms of the parameters appearing in the polynomial defining the curve. This provides an alternative to the language of theta functions. The main result is …
Webencounter: real and complex scalar, spinor and massless vector. Section 3 contains identities useful for performing loop calculations (Feynman parameters, gamma functions and so on). In section 4 I list various facts that possibly come in handy when computing scattering amplitudes at tree level, including facts about gamma matrices and similar ... Web23 de nov. de 2024 · The modified propagator for the scalar field due to the presence of a Dirichlet boundary is computed, and the interaction between the plate and a point-like scalar charge is analysed.

The … Web25 de abr. de 2024 · The dynamics of the scalar field and particle in a conformal frame are considered. The conformal Klein-Gordon equation describing the scalar field is transformed into the quantum Telegraph equation in Minkowski space-time. The conformal factor acts like a background field having a perfect energy-momentum tensor. The scalar field …
