The three extra quasi-Dirac neutrinos are needed to cancel the quadratically divergent contributions of the mirror leptons to the Higgs mass. If the T-parity of the heavy neutrino singlets is chosen to be even, their contributions to lepton avor violating transitions are one-loop nite. The most stringent limits on this scenario result from the non-observation of these transitions. Constraints on neutrino mixing imply an upper bound on the mass of the T-odd mirror leptons at the reach of the LHC and/or future colliders.}, organization = {This work has been supported in part by the Ministry of Science, Innovation and Universities, under grant numbers FPA2016-78220-C3-1,2,3-P (fondos FEDER), and by the Junta de Andalucía grants FQM 101 and SOMM17/6104/UGR.}, publisher = {Springer Nature}, keywords = {Beyond Standard Model}, keywords = {Neutrino physics}, title = {Inverse see-saw neutrino masses in the Littlest Higgs model with T-parity}, doi = {10.1007/JHEP12(2019)154}, author = {Águila Giménez, Francisco Del and Illana Calero, José Ignacio and Pérez Poyatos, José María and Santiago Pérez, José}, }
