    • Experiments report a wide range of values for (Formula presented). Reference 12 gives a “world average” value of (Formula presented) in excellent agreement with ISGW2 3, but experiments quote inconsistent values from (Formula presented) [ALEPH Collaboration, D. Buskuvic, Phys. Lett. B 395, 373 (1997)] to (Formula presented)
