从标准模型到字符串的CP破坏

CP Violation From Standard Model to Strings

Tarek Ibrahim, Pran Nath

摘要:

从标准模型到弦的CP破坏的审查,其中包括粒子物理模型的广泛景观,包括非超对称的4D扩展的标准模型,模型的基础上超对称,额外的维度,弦和膜。讨论的超对称模型包括复杂的mSUGRA及其扩展,而基于额外维度的模型包括5D模型,包括基于扭曲几何的模型。超越标准模型的CP破坏是通过重子生成和轻子生成在宇宙中实现所需重子不对称性的核心。它们也影响各种粒子物理现象:电偶极矩,$g-2$,遗迹密度和超对称理论中的中性伴子暗物质的检测率,大统一和基于弦的模型中的汤川统一,以及sparticle生产截面,以及它们在强子对撞机上的衰变模式和签名。此外,CP破坏可以产生CP偶-CP奇混合,影响中性希格斯谱,并导致在对撞机上可检测到的现象。其中突出的是中性和带电希格斯玻色子玻色子衰变中的CP破坏效应。中微子质量引入了新的CP破坏源,这将在未来的中微子工厂中进行探索。这样的阶段也可以进入质子稳定性粒子相互作用的统一模型。讨论了CP破坏的实验现状,并展望了未来的可能性.

英文摘要:

A review of CP violation from the Standard Model to strings is given which includes a broad landscape of particle physics models, encompassing the non-supersymmetric 4D extensions of the standard model, and models based on supersymmetry, on extra dimensions, on strings and on branes. The supersymmetric models discussed include complex mSUGRA and its extensions, while the models based on extra dimensions include 5D models including models based on warped geometry. CP violation beyond the standard model is central to achieving the desired amount of baryon asymmetry in the universe via baryogenesis and leptogenesis. They also affect a variety of particle physics phenomena: electric dipole moments, $g-2$, relic density and detection rates for neutralino dark matter in supersymmetric theories, Yukawa unification in grand unified and string based models, and sparticle production cross sections, and their decays patterns and signatures at hadron colliders. Additionally CP violations can generate CP even-CP odd Higgs mixings, affect the neutral Higgs spectrum and lead to phenomena detectable at colliders. Prominent among these are the CP violation effects in decays of neutral and charged Higgs bosons. Neutrino masses introduce new sources of CP violation which will be explored in neutrino factories in the future. Such phases can also enter in proton stability in unified models of particle interactions. The current experimental status of CP violation is discussed and possibilities for the future outlined.
