论文摘要
众所周知,中微子的偶极矩会导致重要的天体物理和宇宙学作用。在这方面,在$ u(1)_ {b-l} $模型的背景下,我们开发并提出了新颖的分析公式,以评估中微子的异常磁矩和电偶极矩对恒星能量损失速率的影响,通过对配对的$ e^+e^+e^to(tok,z,z,z,$ prime)的一些常见物理过程。我们的结果表明,恒星能量损耗速率在很大程度上取决于中微子的有效磁矩,也取决于所采用的$ u(1)_ {b-l} $模型的参数。
It is known that the dipole moments of the neutrino lead to important astrophysical and cosmological effects. In this regard, within the context of a $U(1)_{B-L}$ model, we develop and present novel analytical formulas to assess the effects of the anomalous magnetic moment and electric dipole moment of the neutrino on the stellar energy loss rates through some common physical process of pair-annihilation $e^+e^-\to(γ, Z, Z^{\prime})\toν\barν$. Our results show that the stellar energy loss rates strongly depends on the effective magnetic moment of the neutrino, but also on the parameters which characterize the adopted $U(1)_{B-L}$ model.
