非超对称SO(10)大统一中的中间质量标度:重新评价

Intermediate mass scales in the non-supersymmetric SO(10) grand unification: a reappraisal

Stefano Bertolini, Luca Di Luzio, Michal Malinsky

摘要:

本文系统地讨论了非超对称SO(10)方案中规范统一对中间质量尺度的限制。在已有的研究基础上,我们在单圈和双圈水平上引入了U(1)规范混合重整化,并重新评估了双圈β系数。我们评估的影响,额外的希格斯多重态需要在中间阶段的一个现实的质谱,并更新讨论到今天的数据。在所得结果的基础上,讨论了SO(10)破裂模式与两个中间质量尺度的潜在相关性和模式预报性。

英文摘要:

The constraints of gauge unification on intermediate mass scales in non-supersymmetric SO(10) scenarios are systematically discussed. With respect to the existing reference studies we include the U(1) gauge mixing renormalization at the one- and two-loop level, and reassess the two-loop beta-coefficients. We evaluate the effects of additional Higgs multiplets required at intermediate stages by a realistic mass spectrum, and update the discussion to the present day data. On the basis of the obtained results, SO(10) breaking patterns with up to two intermediate mass scales are discussed for potential relevance and model predictivity.
