\begin{abstract} Nowadays, no dark matter candidates have been discovered. Weconsider two possible reasons for that, both related to the approach of on-peakresonance searching for. As is believed usually, a new particle suits theconditions that the ratio of the width to the mass is less than $1-3 \%$ and anarrow width approximation (NWA) is applicable to identify the such typeresonant peak in the invariant mass spectrum of collision products.  In the present paper, in the framework of generalized Yukawa model, we findout the properties of the searched particle when its width is larger than amaximal one expected during experiments and so this state could be missed as anoise. We also ascertain the values of particle's parameters when the NWA isnot applicable and estimate the width value when it happens. These estimationsare relevant to interactions between the Standard model and dark matterparticles. Such approach is focused on the role of couplings and mass valuesintroduced in the model describing interaction of visible and dark matter.  Key words: dark matter; resonance; narrow width approximation; mixing offields.
