四维Scherk-Schwarz超对称破缺

Scherk-Schwarz Supersymmetry Breaking in 4D

Nathaniel Craig, Hou Keong Lou

摘要:

利用维数解构技术,我们提出了完全再现在S^1/Z_2轨道上紧化的具有一般Scherk-Schwarz超对称破缺(SSSB)边界条件的5D超对称理论物理的4D模型。与以前的方法不同,我们的解构只涉及软超对称破缺。解构主义保留了SSSB的许多吸引人的特征,而没有完整的第五维的繁琐架构,紫外线完成的模糊性,或与稳定大半径紧致化相关的挑战。我们继续解构各种具有Scherk-Schwarz边界条件的五维模型,包括折叠超对称性。

英文摘要:

Using the techniques of dimensional deconstruction, we present 4D models that fully reproduce the physics of 5D supersymmetric theories compactified on an S^1/Z_2 orbifold with general Scherk-Schwarz supersymmetry breaking (SSSB) boundary conditions. In contrast to previous approaches, our deconstruction involves only soft supersymmetry breaking. Deconstruction preserves many of the attractive features of SSSB without the cumbersome architecture of a full fifth dimension, ambiguity of the ultraviolet completion, or challenges associated with stabilizing a large radius of compactification. We proceed to deconstruct various five-dimensional models featuring Scherk-Schwarz boundary conditions, including folded supersymmetry.
