We study the model, where the same sector breaks the gauge symmetry and SUSY. In general, the SUSY breaking model without gauge symmetry has a flat direction at the minimum of F-term scalar potential. When we introduce U(1) gauge symmetry to such a SUSY breaking model, there can appear a runaway direction. Such a runway direction can be lifted by loop effects, and the gauge symmetry breaking and SUSY breaking are realized. The R-symmetry, that is assigned to break SUSY, is also spontaneously broken at the vacuum. This scenario can be extended to non-Abelian gauge theories. We also discuss application to the Pati-Salam model and the SU(5) grand unified theory. We see that non-vanishing gaugino masses are radiatively generated by the R-symmetry breaking and the gauge messenger contribution.SpringerJournal Articleapplication/pdfhttp://hdl.handle.net/2115/67916https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/67916/1/JHEP2017-11%2073.pdf1029-8479Journal of High Energy Physics201711732017-11-14enginfo:doi/10.1007/JHEP11(2017)073https://creativecommons.org/licenses/by/4.0/publisher
