Description

Using an anomalous Ward identity for (trace of the stress-energy-momentum tensor) times (electromagnetic current)2 with PCDC (partially conserved dilation current) via two isoscalars epsilon (700) and S* (980) we get lim/subs/ /sub arrow-right//sub infinity/sigma (e+e- → hadrons) / sigma (e+e- → μ+μ-) approx. = 24m/subP/ 2/m/sub epsilon/ 2 approx. = 8 m/subP/ 2 being the average mass2 of the pseudoscalar SU(3) octet
