摘要:

本文研究了紧$SU\left( 3\right)_C\otimes SU\left( 4\right)_{L}\otimes U\left( 1\right)_X$模型中的重子生成问题。利用有限温度有效势方法,结合么正性、稳定性和无鬼质量约束,在模型规范对称性自发破缺的所有步骤中,证明并数值检验了强一级电弱相变(EWPT)的存在.满足EWPT标准的希格斯质量区域进行了讨论。此外,作为我们研究的副产品,通过sphaleron的B-破坏也被强调。

英文摘要:

Baryogenesis in the context of the compact $SU\left( 3\right)_C\otimes SU\left( 4\right)_{L}\otimes U\left( 1\right)_X$ model is investigated. Using the finite temperature effective potential approach together with unitarity, stability and no ghost masses constraints, the existence of a strong first order electroweak phase transition (EWPT) was shown and checked numerically during all steps of the spontaneous breakdown of the gauge symmetry of the model. Higgs masses regions fulfilling the EWPT criteria are also discussed. Moreover, and as a byproduct of our study, the B-violation via sphaleron was also emphasized.
