论文摘要
我们发现，是否具有超重的Higgs三胞胎具有具有标准型号的Higgs Doublet的特殊尺寸-6操作员，即三联三联三联双轴耦合的平方，其标量（伪量表）组件可以得到一个小Quadratic术语，而pseudo-scalar（scaludo-scalar（Scalcalar）的巨额构成量和加重量的scalen and periveent and pendered cancal and gendered scal scal and scalar and scalar and scalar and scalar and scalar and scalar and scalar and scalar。这种分裂的希格斯三重态可以自发地发展一个较小的真空期望值，以实现Majorana Neutmino质量产生，而不会造成任何高维的Lepton数字违规行为，包括著名的Weinberg Dimension-5操作员。另外，它可以介导通过解决哈勃恒定测量中的张力来促进的非标准中微子自我交往。这种有效的理论具有丰富的可观察现象可以由树级的Georgi-Machacek Higgs三胞胎或以一环阶的某些暗物质领域引起的。
We find if a Higgs triplet with hypercharge has a special dimension-6 operator with the standard model Higgs doublet, i.e. a square of the trilinear triplet-doublet coupling, its scalar(pseudo-scalar) component can obtain a small quadratic term while its pseudo-scalar(scalar) and charged-scalar components can hold their masses heavy enough. Such split Higgs triplet can spontaneously develop a small vacuum expectation value to realize a Majorana neutrino mass generation without causing any high-dimensional lepton number violations including the well-known Weinberg dimension-5 operator. Alternatively it can mediate a non-standard neutrino self-interaction motivated by resolving the tension in Hubble constant measurements. This effective theory with rich observable phenomena can be induced by the Georgi-Machacek Higgs triplets at tree level or some dark matter fields at one-loop order.
