实射影平面上的偶层与共振

Even tiers and resonances on the Real Projective Plane

G. Cacciapaglia, B. Kubik

摘要:

在这项工作中,我们专注于各种唯象方面的最轻的甚至层,(2,0)和(0,2),在模型的基础上,在6维的真正的投影平面。我们讨论了由于环路修正的能级谱,以及当两个半径相等时的极限,在这种情况下,两个能级相互混合,并定义了一个新的基。我们还讨论了光谱对两个半径之比的依赖性。这些结果对于理解对撞机(LHC)模型的现象学和预测暗物质的残余丰度是必不可少的。最后,我们估计的半径上的界限,从共振衰变的偶数层在大型强子对撞机,表明它们可以在600 GeV的范围后,2011年的数据的完整分析。

英文摘要:

In this work we focus on various phenomenological aspects of the lightest even tiers, (2,0) and (0,2), in models based on a Real Projective Plane in 6 dimensions. We discuss the spectrum of the levels due to loop corrections, and the limit when the two radii are equal, in which case the two levels mix with each other and a new basis is defined. We also discuss the dependence of the spectrum on the ratio of the two radii. These results are essential to understand the phenomenology of the model at colliders (LHC) and to predict the relic abundance of Dark Matter. Finally, we estimate the bounds on the radius from resonant decays of the even tiers at the LHC, showing that they can be in the 600 GeV range after the complete analysis of the 2011 data.
