Nel<strong>so</strong>n & SeibergR-symmetry causing problemsThe argument of Nel<strong>so</strong>n & SeibergDynamical <strong>SUSY</strong> breaking in a generic, calculable model requires aspontaneously broken R-symmetry.Global U(1) R symmetry: W eff carries charge 2, <strong>so</strong> it must be possibleto write it in terms of a new holomorphic function:W eff= φ 2/qnn f (X a )Vacuum equations: ∂ a f (X b ) = 0f (X b ) = 0 (if 〈 φ n〉≠ 0)n equations in n − 1 unknowns — in<strong>so</strong>luble.(I.P.P.P. — Durham University) <strong>SUSY</strong> <strong>Breaking</strong> Heidelberg 17 / 27
