Softening the Supersymmetric Flavor Problem in Orbifold GUTs Kajiyama, Yuji 15408 Kubo, Jisuke 15093 40211213 40211213 40211213 Terao, Haruhiko 15015 40192653 40192653 AA00773624 The infrared attractive force of the bulk gauge interactions is applied to soften the supersymmetric flavor problem in the orbifold SU~5! grand unified theory of Kawamura. Then this force aligns in the infrared regime the soft supersymmetry breaking terms out of their anarchical disorder at a fundamental scale, in such a way that flavor-changing neutral currents as well as dangerous CP-violating phases are suppressed at low energies. It is found that this dynamical alignment is sufficiently good compared with the current experimental bounds, as long as the diagonalization matrices of the Yukawa couplings are CKM-like. 金沢大学理学部 journal article The American Physical Society 2004-06-11 VoR application/pdf Physical Review D 11 69 116006-1 116006-12 05562821 https://kanazawa-u.repo.nii.ac.jp/record/10282/files/SC-PR-TERAO-H-PhysRevD_69_116006.pdf http://hdl.handle.net/2297/1680 https://kanazawa-u.repo.nii.ac.jp/records/10282 eng https://doi.org/10.1103/physrevd.69.116006 © 2004 The American Physical Society
