Abstract 摘要	5d superconformal field theories (SCFTs) have various string constructions, one of which is type IIB (p,q) 5-brane web, and the 5-brane web is a useful tool to study qualitative and quantitative aspects of 5d SCFTs. We discuss 5d N=1 theories of gauge groups SO(N) and Sp(N) which can be constructed using 5-brane webs with an O5-plane. In this talk, we propose topological vertex formalism with an O5-plane, which enables one to compute the Nekrasov partition functions for 5d theories of gauge groups SO(N) and Sp(N). As an example, we apply the formalism to 5d Sp(1) gauge theory with Nf=0 and 8 flavors. We further explore 5d brane constructions for 5d G2 gauge theories through the Higgsing of SO(7) gauge theory with a hypermultiplet in the spinor representation, and then compute their partition functions based on 5-brane webs, by utilizing the topological vertex method with an O5-plane.
