Abstract
Supersymmetry provides a wellestablished theoretical framework for extensions of the standard model of particle physics and the general understanding of quantum field theories We summarise here our investigations of mathcalN=1 supersymmetric YangMills theory with SU2 gauge symmetry using the nonperturbative firstprinciples method of numerical lattice simulations The strong interactions of gluons and their superpartners the gluinos lead to confinement and a spectrum of bound states including glueballs mesons and gluinoglueballs emerges at low energies For unbroken supersymmetry these particles have to be arranged in supermultiplets of equal masses In lattice simulations supersymmetry can only be recovered in the continuum limit since it is explicitly broken by the discretisation We present the first continuum extrapolation of the mass spectrum of supersymmetric YangMills theory The results are consistent with the formation of supermultiplets and the absence of nonperturbative sources of supersymmetry breaking Our investigations also indicate that numerical lattice simulations can be applied to nontrivial supersymmetric theoriesThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
