Search for light sterile neutrinos from $W^{\pm }$ decays at the LHC

Claudio O. Dib, Choong Sun Kim, Sebastian Tapia Araya

We study the feasibility to observe sterile neutrinos with masses in the range 5 GeV $<m_N<20$ GeV at the LHC, using exclusive semileptonic modes involving pions, $W\to \ell N \…
