WMAP-Compliant Benchmark Surfaces for MSSM Higgs Bosons

J. Ellis, T. Hahn, S. Heinemeyer, K. A. Olive, G. Weiglein

摘要:

我们探索“基准面”适合研究希格斯玻色子的现象学在最小的超对称扩展的标准模型(MSSM),这是选择,使超对称遗迹密度一般是兼容的范围内的冷暗物质密度首选WMAP和其他观测。这些基准面的规定假设,高根质量m_{1/2},软三线性超临界破坏参数A_0和软超临界破坏贡献m_0的夸克和slepton质量是普遍的,但不是那些与希格斯多重态(NUHM框架)。基准面可以表示为M_A-tan_beta平面,其具有固定或系统变化的其他NUHM参数值,例如m_0、m_{1/2}、A_0和Higgs混合参数μ。我们讨论了在Tevatron对撞机,大型强子对撞机,ILC,在B物理和直接暗物质探测实验中,实验探测这些基准表面的前景。附录记录了FeynHiggs代码的发展,使用户能够自己探索符合WMAP的基准表面。

英文摘要:

We explore `benchmark surfaces' suitable for studying the phenomenology of Higgs bosons in the minimal supersymmetric extension of the Standard Model (MSSM), which are chosen so that the supersymmetric relic density is generally compatible with the range of cold dark matter density preferred by WMAP and other observations. These benchmark surfaces are specified assuming that gaugino masses m_{1/2}, soft trilinear supersymmetry-breaking parameters A_0 and the soft supersymmetry-breaking contributions m_0 to the squark and slepton masses are universal, but not those associated with the Higgs multiplets (the NUHM framework). The benchmark surfaces may be presented as M_A-tan_beta planes with fixed or systematically varying values of the other NUHM parameters, such as m_0, m_{1/2}, A_0 and the Higgs mixing parameter mu. We discuss the prospects for probing experimentally these benchmark surfaces at the Tevatron collider, the LHC, the ILC, in B physics and in direct dark-matter detection experiments. An Appendix documents developments in the FeynHiggs code that enable the user to explore for her/himself the WMAP-compliant benchmark surfaces.
