Query: Probing charged lepton number violation via $\ell^\pm \ell^{\prime \pm}
  W^\mp W^\mp$   We study impacts of dimension-five lepton-number violating operators
associated with two same-sign weak bosons, $\ell^\pm \ell^{\prime \pm} W^\mp
W^\mp$, on current and future experiments for neutrino oscillation,
lepton-number violating rare processes and high-energy collider experiments.
These operators can contain important information on the origin of tiny
neutrino masses, which is independent of that from the so-called Weinberg
operator. We examine constraints on the coefficients of the operators by the
neutrino oscillation data. Upper bounds on the coefficients are also
investigated by using the data for processes of lepton number violation such as
neutrinoless double beta decays and $\mu^-$-$e^+$ conversion. These operators
can also be directly tested by searching for lepton-number violating dilepton
production via the same-sign W boson fusion process at high-energy hadron
colliders like the Large Hadron Collider. We find that these operators can be
considerably probed by these current and future experiments.
