没有希格斯玻色子的大统一

Grand Unification without Higgs Bosons

Stephen M. Barr, Xavier Calmet

摘要:

我们将讨论如何将一个没有希格斯粒子的电弱相互作用模型嵌入到大统一理论中。在弱相互作用的SU(2)扇区中需要一个非平凡的不动点,再加上规范耦合的数值统一的要求,导致了在不动点区域中SU(2)规范耦合值的预测。为了解决W玻色子弹性散射中的么正性问题,不动点区域必须在TeV区域。我们发现统一尺度大约在10^{14} GeV。因此,可行的大统一理论必须保持重子数守恒。我们讨论如何建立这样一个模型,而不使用希格斯玻色子玻色子。

英文摘要:

We discuss how a model for the electroweak interactions without a Higgs could be embedded into a grand unified theory. The requirement of a non-trivial fixed point in the SU(2) sector of the weak interactions together with the requirement of the numerical unification of the gauge couplings leads to a prediction for the value of the SU(2) gauge coupling in the fixed point regime. The fixed point regime must be in the TeV region to solve the unitarity problem in the elastic scattering of W bosons. We find that the unification scale is at about 10^{14} GeV. Viable grand unified theories must thus conserve baryon number. We discuss how to build such a model without using Higgs bosons.
