In addition we study the asymptotic behavior of the two-, three- and four-point Green's functions with external electroweak bosons in the limit where the physical sparticle masses are very large in comparison with the electroweak scale. We find that in this limit all the effects produced by the supersymmetric particles can either be absorbed in the standard model parameters and gauge bosons wave functions, or else they are suppressed by inverse powers of the supersymmetric particle masses. This work, therefore, completes the proof of decoupling of the heavy supersymmetric particles from the standard ones in the electroweak bosons effective action and in the sense of the Appelquist-Carazzone theorem; we started this proof in a previous work. From the point of view of effective field theories this work can be seen as a (partial) proof that the SM can indeed be obtained from the MSSM as the quantum low-energy effective theory of the latter when the SUSY spectra are much heavier than the electroweak scale. eng The SM as the quantum low-energy effective theory of the MSSM journal article URL https://docta.ucm.es/bitstreams/580a207e-66bd-47f5-98ea-8c62cf73a0fd/download File MD5 8c07c6cec88c9157f948315a9d65a79e 398912 application/pdf DobadoAntonio54.pdf URL https://docta.ucm.es/bitstreams/6b24e23d-376d-4105-bd99-e04b3ccde55d/download File MD5 33c6e7a6a53487e284e3638906c0db0d 393881 application/pdf DobadoAntonio54preprint.pdf
