MSSM的手性延伸

Chiral Extensions of the MSSM

Gabriele Ferretti, Denis Karateev

摘要:

我们给出了一类MSSM的推广,其特征是由于额外的U '(1)规范对称性,在超势中没有重子或轻子数违反项,并且具有完全手征场内容(没有μ项).极小模型由通常的物质扇区和族相关的U '(1)电荷,六个希格斯弱二重态和三个单重态组成,这些单重态需要给希格斯玻色子以质量并消除异常。我们讨论了它的主要特点,如树级质谱和风味变化过程的限制。

英文摘要:

We present a class of extensions of the MSSM characterized by a fully chiral field content (no mu-terms) and no baryon or lepton number violating term in the superpotential due to an extra U'(1) gauge symmetry. The minimal model consist of the usual matter sector with family dependent U'(1) charges, six Higgs weak doublets, and three singlets required to give masses to the Higgsinos and cancel anomalies. We discuss its main features such as the tree level mass spectrum and the constraints on flavor changing processes.
