Search for a Light Scalar Boson Emitted in Nuclear Decay

Abstract
The possibility that a scalar boson is sometimes emitted in the decay of He4(20.1 MeV, 0+) is examined experimentally. Finding no positive evidence the authors exclude scalars with Higgs-like couplings for 3mϕ14 MeV/c2, where the precise range depends upon the model.
