Method of Studying Decays with One Missing Particle

Predictions from [4]. (a) Inflaton branching ratios to various two-body final states as functions of inflaton mass for GeV. Above 2.5 GeV only quark-antiquark and dilepton modes are predicted. In the intermediate region no reliable prediction is given. (b) Inflaton lifetime as a function of the inflaton mass . The lifetime can be up to two times smaller, depending on model-dependent parameters.
