摘要：

标准模型（SM）的扩展与两个复杂的$SU(2)_{L}$标量三元组，使一个有II型跷跷板机制与纹理零中微子质量矩阵的操作一致。这个框架预测额外的双电荷，单电荷和中性无自旋状态。我们发现，对于某些值的模型参数，有足够的质量分裂之间的两个双电荷状态（$H_1^{\pm\pm}, H_2^{\pm\pm}$），允许衰变$H_1^{\pm\pm} \to H_2^{\pm\pm} h $，从而导致这种情况下的一个独特的签名。我们表明，这种模式产生的最终状态$2(\ell^{\pm} \ell^{\pm}) + 4b + \mET~$可以观察到在高能量，高亮度（HE-HL）运行的14 TeV的大型强子对撞机（LHC），也在100 TeV的未来圆形对撞机（FCC-hh）。

英文摘要：

The extension of the Standard Model (SM) with two complex $SU(2)_{L}$ scalar triplets enables one to have the Type II seesaw mechanism operative consistently with texture-zero neutrino mass matrices. This framework predicts additional doubly charged, singly charged and neutral spinless states. We show that, for certain values of the model parameters, there is sufficient mass splitting between the two doubly charged states ( $H_1^{\pm\pm}, H_2^{\pm\pm}$) that allows the decay $H_1^{\pm\pm} \to H_2^{\pm\pm} h $, and thus leads to a unique signature of this scenario. We show that the final state $2(\ell^{\pm} \ell^{\pm}) + 4b + \mET~$ arising from this mode can be observed at the high energy, high luminosity (HE-HL) run of the 14 TeV Large Hadron Collider (LHC), and also at a 100 TeV Future Circular Collider (FCC-hh).
