Spinning amplitudes from scalar amplitudes
نویسندگان
چکیده
We provide a systematic method to compute tree-level scattering amplitudes with spinning external states from scalar in arbitrary spacetime dimensions. write down analytic answers for various amplitudes, including the four graviton amplitude due massive spin $J$ exchange. verify results by computing angular distributions 3 + 1 dimensions using identities involving Jacobi polynomials.

Scalar Mesons and Multichannel Amplitudes
Properties of scalar–isoscalar mesons are analysed in an unitary model using separable interactions in three decay channels: ππ , KK and an effective 2π2π. We obtain different solutions by fitting various data on the ππ and KK phase shifts and inelasticities including the CERN-Cracow-Munich measurements of the πp↑ → π+π−n reaction on a polarized target. Analytical structure of the meson-meson m...
متن کاملOn the Construction of Scattering Amplitudes for Spinning Massless Particles
In this paper the general form of scattering amplitudes for massless particles with equal spins s (ss → ss) or unequal spins (sasb → sasb) are derived. The imposed conditions are that the amplitudes should have the lowest possible dimension, have propagators of dimension m−2, and obey gauge invariance. It is shown that the number of momenta required for amplitudes involving particles with s > 2...
متن کاملMassive Loop Amplitudes from Unitarity
We show, for previously uncalculated examples containing a uniform mass in the loop, that it is possible to obtain complete massive one-loop gauge theory amplitudes solely from unitarity and known ultraviolet or infrared mass singularities. In particular, we calculate four-gluon scattering via massive quark loops in QCD. The contribution of a heavy quark to five-gluon scattering with identical ...
متن کاملRelating spectral indices to tensor and scalar amplitudes in inflation.
Within an expansion in slow-roll in ation parameters, we derive secondorder expressions relating the ratio of tensor to scalar density perturbations and the spectral index of the scalar spectrum. We nd that \corrections" to previously derived formulae can dominate if the tensor to scalar ratio is small. For instance, if V V 00=(V ) 6= 1 or if mP l=(4 ) jV 000=V j > 1, where V ( ) is the in aton...
متن کاملScalar diagrammatic rules for Born amplitudes in QCD
We show that all Born amplitudes in QCD can be calculated from scalar propagators and a set of threeand four-valent vertices. In particular, our approach includes amplitudes with any number of quark pairs. The quarks may be massless or massive. The proof of the formalism is given entirely within quantum field theory.
