An evaluation of the analytic continuation by duality technique
In Nucl. Phys. B391 (1993) 127, Sundrum and Hsu estimated the value of the oblique correction parameter S for walking technicolor theories using a technique called Analytic Continuation by Duality (ACD). We apply the ACD technique to the perturbative vacuum polarization function and find that it fai...

| description | In Nucl. Phys. B391 (1993) 127, Sundrum and Hsu estimated the value of the oblique correction parameter S for walking technicolor theories using a technique called Analytic Continuation by Duality (ACD). We apply the ACD technique to the perturbative vacuum polarization function and find that it fails to reproduce the well known result S=1/6\pi. This brings into question the reliability of the ACD technique and the Sundrum and Hsu estimate of S. |
