论文摘要
\ begin {Abstract}如今,没有发现暗物质候选者。我们考虑了两个可能的原因,这两者都与搜索峰值共振的方法有关。通常,新粒子适合宽度与质量的比率小于$ 1-3 \%$,并且狭窄的宽度近似值(NWA)适用于识别碰撞产物不变的质谱中的这种类型的共振峰。 在本文中,在广义Yukawa模型的框架中,当搜索粒子的宽度大于实验过程中预期的最大值时,我们发现了搜索粒子的特性,因此可以遗漏该状态作为噪声。当NWA不适用并在发生时估计宽度值时,我们还确定了粒子参数的值。这些估计与标准模型和暗物质颗粒之间的相互作用有关。这种方法集中在描述可见光和暗物质相互作用的模型中引入的耦合和质量值的作用。 关键词:暗物质;谐振;狭窄的宽度近似;田野的混合。
\begin{abstract} Nowadays, no dark matter candidates have been discovered. We consider two possible reasons for that, both related to the approach of on-peak resonance searching for. As is believed usually, a new particle suits the conditions that the ratio of the width to the mass is less than $1-3 \%$ and a narrow width approximation (NWA) is applicable to identify the such type resonant peak in the invariant mass spectrum of collision products. In the present paper, in the framework of generalized Yukawa model, we find out the properties of the searched particle when its width is larger than a maximal one expected during experiments and so this state could be missed as a noise. We also ascertain the values of particle's parameters when the NWA is not applicable and estimate the width value when it happens. These estimations are relevant to interactions between the Standard model and dark matter particles. Such approach is focused on the role of couplings and mass values introduced in the model describing interaction of visible and dark matter. Key words: dark matter; resonance; narrow width approximation; mixing of fields.
