By using excursion measure Poisson kernel method, we obtain a second-order differential equation of the intersection probability of Brownian motion andSLEκ. Moreover, we find a transformation such that the second-order differential equation transforms into a hypergeometric differential equation. Then, by solving the hypergeometric differential equation, we obtain the explicit formula of the intersection probability for the trace of the chordalSLEκand planar Brownian motion started from distinct points in an upper half-planeH-.
