Abstract

Measurements by various international groups of researchers determine the strength of the weak interaction of the neutron, which gives us unique information on the question of the quark mixing. Neutron decay experiments now challenge the Standard Model of elementary particle physics with a deviation, 2.7 times the stated error.
