The K−K^-K− meson (suˉs\bar{u}suˉ) is produced in cosmic ray interactions and can undergo a strong interaction with a stationary proton (p\text{p}p) according to the following equation:
K−+p→K++X K^- + \text{p} \rightarrow K^+ + \text{X} K−+p→K++XWhat is the quark composition of particle X\text{X}X?
