6D strings and exceptional instantons
6D strings and exceptional instantons
We propose new ADHM-like methods to compute the Coulomb branch instanton partition functions of 5D and 6D supersymmetric gauge theories, with certain exceptional gauge groups or exceptional matters. We study ${G}_{2}$ theories with ${n}_{\mathbf{7}}\ensuremath{\le}3$ matters in $\mathbf{7}$ and $SO(7)$ theories with ${n}_{\mathbf{8}}\ensuremath{\le}4$ matters in the spinor representation $\mathbf{8}$. We also …
