Search for long-lived particles decaying to $e^{\pm} μ^{\mp} ν$

LHCb collaboration, R. Aaij, C. Abellán Beteta +975

Long-lived particles decaying to $e^{\pm} μ^{\mp} ν$ , with masses between 7 and $50$ GeV/c $^{2}$ and lifetimes between 2 and $50$ ps, are searched for by looking at displaced vertices co…

Search for heavy neutral leptons in $W^{+} \to μ^{+} μ^{\pm} jet$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +980

A search is performed for heavy neutrinos in the decay of a $W$ boson into two muons and a jet. The data set corresponds to an integrated luminosity of approximately $3.0 \text{ fb…
