摘要:

研究了额外单态对电弱相变强度和相应的引力波谱的影响。我们考虑的标准模型(SM)扩展的单重标量与多重数N耦合到SM希格斯偶线。在施加所有的理论和实验的限制,并定义的区域,EWPT是强一阶,我们得到的区域中的GWs频谱可以达到不同的未来的实验,如LISA和DECIGO。

英文摘要:

We investigate the effect of extra singlets on the electroweak phase transition (EWPT) strength and the spectrum of the corresponding gravitational waves (GWs). We consider here the standard model (SM) extended with a singlet scalar with multiplicity N coupled to the SM Higgs doublet. After imposing all the theoretical and experimental constraints and defining the region where the EWPT is strongly first order, we obtain the region in which the GWs spectrum can be reached by different future experiments such as LISA and DECIGO.
