These are naturally associated to Hitchin systems with wild ramification whose spectral curves provide the relevant Seiberg-Witten geometries. We propose that the prepotential of these gauge theories on the Omega-background can be obtained from the corresponding irregular conformal blocks on the Riemann surfaces via a generalization of the coherent state construction to the case of higher order singularities.</p>1 aBonelli, Giulio1 aMaruyoshi, Kazunobu1 aTanzini, Alessandro  uhttp://hdl.handle.net/1963/5184
