Abstract
We propose new topological vertex formalism for Type IIB 5-brane web with an O5-plane. We apply our proposal to 5d Sp(1) gauge theory with flavors to compute the topological string partition functions and check the agreement with the known results. Especially for the case, which corresponds to E-string theory on a circle, we obtain a new, yet simple, expression of the partition function with two Young diagram sum.
