: We study the existence of collision local time of two independent subfractional Brownian motions with different coefficients in ( − 12 , 12 ) using an alternative expression. We prove that the collision local time is a Hida distribution based on the canonical framework of white noise analysis, and get chaos expansions. Finally, we show that the collision local time exists in ( L 2 ) under appropriate conditions.
