Like-sign dileptons with mirror type composite neutrinos at the HL-LHC

Abstract

Within a mirror type assignment for the excited composite fermions the neutrino mass term is built up from a Dirac mass, $m_{\ast }$, which gives the mass of charged lepton component of the $SU(2)$, right-handed, doublet, and a Majorana mass, $m_L$, for the left-handed component (singlet) of the excited neutrino. The mass matrix is diagonalized leading to two Majorana mass eigenstates. The active neutrino field ${\nu }_R^{\ast }$ is thus a superposition of the two mass eigenstates with mixing coefficients which depend on the ratio $m_L/m_{\ast }$. We discuss the prospects of discovery of these physical states at the HL-LHC as compared with the previous searches of composite Majorana neutrinos at the LHC based on sequential type Majorana neutrinos.
