The 3-3-1 Model with Exotic Electric Charges, Right-Handed Neutrinos with Type-I+ii Seesaw Mechanism and Its Effects on LFV
arxiv(2024)
摘要
In this research, we propose a modified version of the 3-3-1 model,incorporating a type I+II seesaw mechanism and Z4 discrete symmetry, as aframework for investigating lepton flavor-violating (LFV) decays. This modelsuccessfully yields the left-handed neutrinos mass square difference in the eVscale, with specific values of mass square differences; and generates mixingangles that align with experimental data. Furthermore, we develop SARAH andSPheno algorithms tailored for our modified model, enabling us to estimate themagnitude of LFV observables. Our calculations indicate favorable results forvarious LFV branching ratios. These findings demonstrate improved agreementwith experimental measurements compared to previously reported results, whichtypically fall within the range of 10^-2 to 10^-6.
