广义轻子数与暗左右规范模型

Generalized Lepton Number and Dark Left-Right Gauge Model

Shaaban Khalil, Hye-Sung Lee, Ernest Ma

摘要:

在粒子相互作用的左右规范模型中,左手费米子偶(nu,e)_L和右手费米子偶(n,e)_R通过一个标量双偶偶连接,使得e_L和e_R,nu_L和n_R成对形成质量项。假设后一种联系被切断而不影响前一种联系,那么nR就不是nu L的质量伙伴,并且正如我们在本文中所表明的,成为暗物质的候选者,这与最近的PAMELA和ATIC观测有关。我们在一个特定的非超对称模型中实现了这一点,在这个模型中可以定义一个广义轻子数,使得在R =(-1)^{3B+L+2 j}下n_R和W_R是奇数。也预言了费米轻子夸克。

英文摘要:

In a left-right gauge model of particle interactions, the left-handed fermion doublet (nu,e)_L is connected to its right-handed counterpart (n,e)_R through a scalar bidoublet so that e_L pairs with e_R, and nu_L with n_R to form mass terms. Suppose the latter link is severed without affecting the former, then n_R is not the mass partner of nu_L, and as we show in this paper, becomes a candidate for dark matter which is relevant for the recent PAMELA and ATIC observations. We accomplish this in a specific nonsupersymmetric model, where a generalized lepton number can be defined, so that n_R and W_R are odd under R = (-1)^{3B+L+2j}. Fermionic leptoquarks are also predicted.
