Abstract:We propose 5-brane webs for 5d N=1 G_2 gauge theories. From a Higgsing of the SO(7) gauge theory with a hypermultiplet in the spinor representation, we construct two types of 5-brane web configurations for the pure G_2 gauge theory using an O5-plane or an \tilde{O5}-plane. Adding flavors to the 5-brane web for the pure G_2 gauge theory is also discussed. Based on the obtained 5-brane webs, we compute the partition functions for the 5d G_2 gauge theories using the recently suggested topological vertex formulation with an O5-plane, and we find agreement with known results.
