粒子物理学的金字塔方案
A Pyramid Scheme for Particle Physics
摘要：
我们介绍了一个新的模型，金字塔计划，直接调解超对称性破缺，这是兼容的宇宙学超对称性破缺（CSB）的想法。它使用了大统一的三位一体化方案，避免了标准模型规范耦合中的朗道极点问题。它还避免了最近曝光的问题，这些问题与由于自发破缺的隐藏扇区重子数的伪南武-戈德斯通玻色子（PNGB）的发射而导致的快速恒星冷却有关。有了一定的R对称性破缺质量模式（CSB或多或少需要这种模式），金字塔方案导致了一种暗物质候选者，它主要衰变为轻子，其截面与各种最近的观测结果一致。暗物质粒子不是热WIMP，而是具有新的强相互作用的粒子，产生于其他标量的晚期衰变，可能是QCD轴子的超伴子，再加热温度在TeV范围内。这与重子发生的各种情况是兼容的，包括一些利用金字塔计划的特定功能的新情况。
英文摘要：
We introduce a new model, the Pyramid Scheme, of direct mediation of SUSY breaking, which is compatible with the idea of Cosmological SUSY Breaking (CSB). It uses the trinification scheme of grand unification and avoids problems with Landau poles in standard model gauge couplings. It also avoids problems, which have recently come to light, associated with rapid stellar cooling due to emission of the pseudo Nambu-Goldstone Boson (PNGB) of spontaneously broken hidden sector baryon number. With a certain pattern of R-symmetry breaking masses, a pattern more or less required by CSB, the Pyramid Scheme leads to a dark matter candidate that decays predominantly into leptons, with cross sections compatible with a variety of recent observations. The dark matter particle is not a thermal WIMP but a particle with new strong interactions, produced in the late decay of some other scalar, perhaps the superpartner of the QCD axion, with a reheat temperature in the TeV range. This is compatible with a variety of scenarios for baryogenesis, including some novel ones which exploit specific features of the Pyramid Scheme.
