Query: Displaced vertices and long-lived charged particles in the NMSSM with
  right-handed sneutrinos   We study LHC signatures of displaced vertices and long-lived charged
particles within the context of the Next-to-Minimal Supersymmetric Standard
Model with right-handed (RH) sneutrinos. In this construction the RH neutrino
can be produced directly from Higgs decays or in association with a RH
sneutrino when the latter is the lightest supersymmetric particle. The RH
neutrino is generally long-lived, since its decay width is proportional to the
neutrino Yukawa, a parameter which is predicted to be small. The RH neutrino
late decay can therefore give rise to displaced vertices at the LHC, which can
be identified through the decay products, which involve two leptons (2l+ MET)
or a lepton with two jets (ljj). We simulate this signal for the current LHC
configuration (a centre of mass of 8 TeV and an integrated luminosity of L=20
fb^-1), and a future one (13 TeV and L=100 fb^-1). We show that a region of the
parameter space of this model can be probed and that the RH neutrino mass can
be reconstructed from the end-point of the two-lepton invariant mass
distribution or the central value of the mass distribution for two jets plus
one lepton. Another exotic signature of this construction is the production of
a long-lived stau. If the stau is the next-to-lightest supersymmetric particle,
it can decay through diagrams involving the small neutrino Yukawa, and would
escape the detector leaving a characteristic trail. We also simulate this
signal for various benchmark points and show that the model can be within the
reach of the future run of the LHC.
