拉格朗日標準模型是粒子物理學中的一種基本模型，用于描述基本粒子之間相互作用的方式。它是由意大利物理學家拉格朗日在19世紀初提出的，后來被愛因斯坦等人進一步發(fā)展和完善。

拉格朗日標準模型包括了四種基本相互作用：強相互作用、弱相互作用、電磁相互作用和重力相互作用。其中前三種相互作用是通過交換粒子進行傳遞的，而重力是通過曲率來傳遞的。

拉格朗日標準模型中的基本粒子包括：夸克、輕子、光子和引力子。其中夸克和輕子是構成物質(zhì)的基本粒子，光子是電磁相互作用的載體，引力子是重力相互作用的載體。

拉格朗日標準模型是現(xiàn)代粒子物理學的基礎，它成功地解釋了許多實驗觀測到的現(xiàn)象，但也存在一些未解決的問題，例如暗物質(zhì)和暗能量的本質(zhì)。以下為拉格朗日標準模型：
