We present data obtained at the ISR, on the determination of the ratio of photons and pi0 at 30.6 and 53.2 GeV center of mass and we compare the results with our previous measurement at View the MathML source GeV. The ratio View the MathML source integrated over the interval 0.1 ⩽ χT ⩽ 0.2 is (1.6 ± 0.5) × 10−2 and we obtain an indication of a universal χT dependence.

Abstract

We present data obtained at the ISR, on the determination of the ratio of photons and pi0 at 30.6 and 53.2 GeV center of mass and we compare the results with our previous measurement at View the MathML source GeV. The ratio View the MathML source integrated over the interval 0.1 ⩽ χT ⩽ 0.2 is (1.6 ± 0.5) × 10−2 and we obtain an indication of a universal χT dependence.
