超对称模型中重轻子Q球的基态

The ground states of baryoleptonic Q-balls in supersymmetric models

Ian M. Shoemaker, Alexander Kusenko

摘要:

在标准模型的超对称推广中,所有稳定的Q球都与一些平坦的方向相关联。我们证明,如果平坦方向同时具有重子数和轻子数,则在基态,Q球内的标量场可以稍微偏离平坦方向。我们确定了这种非拓扑孤子的真实基态,包括电中性和带电Q球。

英文摘要:

In supersymmetric generalizations of the Standard Model, all stable Q-balls are associated with some flat directions. We show that, if the flat direction has both the baryon number and the lepton number, the scalar field inside the Q-ball can deviate slightly from the flat direction in the ground state. We identify the true ground states of such nontopological solitons, including the electrically neutral and electrically charged Q-balls.
