True muonium (TM) (μ ⁺ μ ⁻) is the heaviest and smallest bound state not containing hadrons, after TM (τ ⁺ τ ⁻) and mu-tauonium (μ ^± τ ^∓). One of the proposed methods to observe the spin 1 fundamental state of TM, which has the smallest lifetime among TM spin 1 states, was to build an e ⁺ e ⁻ collider with a large crossing angle (θ ∼ 30°) in order to provide TM with a large boost and detect its decay vertex in e ⁺ e ⁻. The following paper will instead show that TM excited states can be observed in relatively large quantities ( O (10)/month) at a e ⁺ e ⁻ collider with standard crossing angle, after setting their center-of-mass energy to the TM mass (∼2m _μ = 211.4 MeV).

在具有标准交叉角的 e + e − 对撞机上产生真正的锷共振

真锷 (TM) (μ ⁺ μ ⁻ ) 是不包含强子的最重和最小束缚态，在 TM (τ ⁺ τ ⁻ ) 和 mu-tauium (μ ^± τ ^∓）。所提出的观察 TM 自旋 1 基本态（TM 自旋 1 态中寿命最短）的方法之一是建立一个e ⁺ e ⁻具有大交叉角的对撞机 (θ∼ 30°），以便为TM提供较大的提升并检测其衰减顶点e ⁺ e ^- .接下来的论文将表明可以观察到相对大量的 TM 激发态（ 氧 (10)/月)e ⁺ e ⁻将质心能量设置为 TM 质量后，具有标准交叉角的对撞机 (∼2米 _μ = 211.4 MeV）。
