超无标度F-SU(5):动态测定M_{1/2}和tan β

Super No-Scale F-SU(5): A Dynamic Determination of M_{1/2} and tan beta

Tianjun Li, James A. Maxin, Dimitri V. Nanopoulos, Joel W. Walker

摘要:

我们研究了无标度F-SU(5)中的Higgs势,F-SU(5)是建立在Flipped SU(5)x U(1)X大统一理论的三脚架基础上的一个模型,额外的F理论导出的TeV标度类矢量粒子多重态,以及无标度超引力的高标度边界条件。V_min是辐射电弱对称性破缺后的最小势,它是普适加耿诺边界质量M_{1/2}在固定Z玻色子质量下与Higgs真空期望值之比tanβ的函数。边界处的双线性Higgs软项B_mu的无标度无效将V_min(M_{1/2})减小为一维依赖性,其可以被二次最小化。这种“超级无标度”条件动态地将tan β和M_{1/2}固定在V_min的局部最小值。令人难以置信的是,这种理论上建立的二次势的壁在下降中与以前现象学上青睐的“黄金点”和“黄金带”合并成惊人的并发性。

英文摘要:

We study the Higgs potential in No-Scale F-SU(5), a model built on the tripodal foundations of the Flipped SU(5) x U(1)_X Grand Unified Theory, extra F-theory derived TeV scale vector-like particle multiplets, and the high scale boundary conditions of No-Scale Supergravity. V_min, the minimum of the potential following radiative electroweak symmetry breaking, is a function at fixed Z-Boson mass of the universal gaugino boundary mass M_{1/2} and tanβ, the ratio of Higgs vacuum expectation values. The No-Scale nullification of the bilinear Higgs soft term B_mu at the boundary reduces V_min(M_{1/2}) to a one dimensional dependency, which may be secondarily minimized. This "Super No-Scale" condition dynamically fixes tan beta and M_{1/2} at the local minimum minimorum of V_min. Fantastically, the walls of this theoretically established secondary potential coalesce in descent to a striking concurrency with the previously phenomenologically favored "golden point" and "golden strip".
