| contents | This paper investigates the relationships between closed and mixed string amplitudes at the tree level in string theory. Through the analytic continuation of complex variables, we establish a factorization of closed string amplitudes into those involving ($n-2$) open strings and a single closed string. Expressions for four-, five-, and six-point amplitudes are provided, along with systematic formulations for $n$ strings. The paper addresses possible correction terms arising from integration along infinite tubes during the Wick rotation process. In the field theory limit, the correction terms become negligible due to being of subleading order. |
