We derive two field theory models of interacting dark energy, one in which dark energy is associated with the quintessence and another in which it is associated with the tachyon. In both, instead of choosing arbitrarily the potential of scalar fields, these are specified implicitly by imposing that the dark energy fields must behave as the new agegraphic dark energy. The resulting models are compared with the Pantheon supernovae sample, CMB distance information from Planck 2015 data, baryonic acoustic oscillations (BAO) and Hubble parameter data. For comparison, the noninteracting case and the [Formula: see text] model also are considered. By use of the AIC and BIC criteria, we have obtained strong evidence in favor of the two interacting models, and the coupling constants are nonvanishing at more than [Formula: see text] confidence level.

与暗物质相互作用的精髓和快子暗能量：观测约束和模型选择

我们推导出两种相互作用暗能量的场论模型，一种是暗能量与本质相关联，另一种是与快子相关联。在这两种情况下，不是任意选择标量场的潜力，而是通过强加暗能量场必须表现为新的时代暗能量来隐含地指定这些。将所得模型与万神殿超新星样本、Planck 2015 数据中的 CMB 距离信息、重子声学振荡 (BAO) 和哈勃参数数据进行比较。为了比较，还考虑了非交互情况和[公式：见文本]模型。通过使用 AIC 和 BIC 标准，我们获得了支持这两个相互作用模型的有力证据，并且耦合常数在超过 [公式：见文本] 置信水平时不为零。
