"The Lifetime of the Neutral Pion"

Dr. Ilya Larin
ITEP, Moscow, Russia


A precision measurement of the neutral pion lifetime via the Primakoff effect was carried out by the PrimEx experiment at Jefferson Lab using the Hall B photon tagger and a high-resolution electromagnetic calorimeter. The neutral pion lifetime was extracted from the measured cross sections using theoretical models. The result of this fundamental quantity is 2.5 times more precise than the present world average of all measurements as reported in the Particle Data Book and consistent with current theoretical predictions.
