Test of {CP} Invariance in $\Lambda^0$ Decay

In an experiment at the CERN intersecting storage rings with √ s = 31 GeV, we have measured αP , the product of asymmetry parameter and polarization, for Λ 0 's and Λ 0 's produced in p p and pp interactions, respectively. The ratio, (αP) Λ /(αP Λ = −1.04±0.29 , is consistent with the value −1, and constitutes the first test of CP invariance in Λ decay.

The ratio CONST/CONST is obtained under assumption of POL(LAMBDA) = POL(LAMBDABAR).

POLARIZATION AND ANGULAR DISTRIBUTIONS IN ELASTIC P P SCATTERING AT 100-GEV AND 300-GEV.

Snyder, J.H. ; Auer, I.P. ; Bruckner, W. ; et al.
Phys.Rev.Lett. 41 (1978) 781-784, 1978.
Inspire Record 132550 DOI 10.17182/hepdata.20889

Measurements of the polarization parameter and angular distributions in pp elastic scattering at incident energies of 100 and 300 GeV are reported. The data cover the kinematic range 0.18<−t<2.0 GeV2. They are found to be consistent with absorption-model predictions.
