We study two and three-point tree-level amplitudes of open strings. These amplitudes are reduced from higher-point correlation functions by using mostly BRST exact operators for gauge fixing. For simplicity. we focus on an open string tachyon. https://www.ivoryjinelle.com/limited-value-Hunting-Camo-iPhone-SE-2nd-3rd-Gen-Pro-Case-p79729-hot-value/
