幻影型号面对LHC：I. Kahler稳定的杂种优势弦论
Mirage Models Confront the LHC: I. Kahler-Stabilized Heterotic String Theory
摘要：
我们从欧洲核子研究中心（CERN）大型强子对撞机（LHC）的现有数据出发，开始研究一类由弦激发的有效超引力理论。我们将首先考虑杂合弦论的情况，在这种情况下，介子通过对卡勒度规的非微扰修正而稳定。该模型具有高度约束性，因此具有预测性。我们发现，大部分合理的参数空间提供给模型-代表强动力学的假设高根诺凝聚在隐藏的部门-现在观测不赞成的大型强子对撞机的结果。剩余的大部分理论驱动的参数空间可以用已经收集的数据进行探测，剩余的大部分将在质心能量为13 TeV的运行的第一年内进行明确的探索。一些基准点的预期签名进行了讨论。我们发现，该模型的生存空间作出了精确的预测，许多超伙伴质量的关系，以及正确的暗物质遗迹密度的获得方式。对当前和未来的暗物质搜索实验的影响进行了讨论。
英文摘要：
We begin the study of a class of string-motivated effective supergravity theories in light of current data from the CERN Large Hadron Collider (LHC). The case of heterotic string theory, in which the dilaton is stabilized via non-perturbative corrections to the Kahler metric, will be considered first. This model is highly constrained and therefore predictive. We find that much of the reasonable parameter space afforded to the model -- representing the strong dynamics of a presumed gaugino condensation in the hidden sector -- is now observationally disfavored by the LHC results. Most of the theoretically-motivated parameter space that remains can be probed with data that has already been collected, and most of the remainder will be definitively explored within the first year of operation at center of mass energy of 13 TeV. Expected signatures for a number of benchmark points are discussed. We find that the surviving space of the model makes a precise prediction as to the relation of many superpartner masses, as well as the manner in which the correct dark matter relic density is obtained. Implications for current and future dark matter search experiments are discussed.
