扭曲的$R-$奇偶校验违反

Warped $R-$Parity Violation

B. C. Allanach, A. M. Iyer, K. Sridhar

摘要:

我们考虑了一个介于普朗克尺度和大统一尺度之间的修正的Randall-Sundrum(RS)框架。在这种情况下,RS作为一种风味理论而不是作为层次问题的解决方案。后者是解决了超对称的体积,使最小的超对称标准模型是有效的四维理论。物质场被局部化,以适应费米子质量和混合数据。如果$R$ -宇称违反条款是允许的超势,他们的数量级在整个味空间,然后预测,导致丰富的味纹理。如果$R$ -宇称违反中微子质量的贡献有所抑制,那么轻子数违反模型存在,它解释了中微子振荡数据,而不与当前的实验界限相矛盾。另一个有希望的模型是一个重子数被违反和狄拉克中微子质量的结果完全从费米子局域化。我们勾勒出可能的重子数和轻子数违反情况下的发现签名。

英文摘要:

We consider a modified Randall-Sundrum (RS) framework between the Planck scale and the GUT scale. In this scenario, RS works as a theory of flavour and not as a solution to the hierarchy problem. The latter is resolved by supersymmetrising the bulk, so that the minimal supersymmetric standard model being the effective 4-dimensional theory. Matter fields are localised in the bulk in order to fit fermion-mass and mixing-data. If $R$-parity violating terms are allowed in the superpotential, their orders of magnitude throughout flavour space are then predicted, resulting in rich flavour textures. If the $R$-parity violating contributions to neutrino masses are somewhat suppressed, then lepton-number violating models exist which explain the neutrino oscillation data while not being in contradiction with current experimental bounds. Another promising model is one where baryon number is violated and Dirac neutrino masses result solely from fermion localisation. We sketch the likely discovery signatures of the baryon-number and the lepton-number violating cases.
