And they hypothesized that the anomaly could be explained by a new particle, which they’re temporarily calling an " X boson, " and a fifth fundamental force.

他们假设这种异常现象可以用一种新粒子和第五种基本力来解释，他们暂时将其称为“X 玻色子”。

Since then, a team of theoretical physicists in California have looked at the data, and think the anomaly could be explained by a fifth fundamental force of nature.

从那以后，加州的一组理论物理学家研究了这些数据， 认为这种异常现象可以用自然界的第五种基本力来解释。

The hypothetical new interaction could be what he and his colleagues call the flavour force—a fifth fundamental force of nature besides gravity and the three of the Standard Model.

假设的新相互作用可能是他和他的同事所说的味道力——除了重力和标准模型中的三种自然力之外的第五个基本自然力。
