Query: Slepton pair production in e+e- collision in supersymmetric left-right
  model   The pair production of sleptons in electron-positron collisions is
investigated in a supersymmetric left-right model. The cross section is found
considerably larger than in the minimal supersymmetric version of the Standard
Model (MSSM) because of more contributing graphs. A novel process is a doubly
charged higgsino exchange in u-channel, which makes the angular distribution of
the final state particles and the final state asymmetries to differ from those
of the MSSM. It also allows for the flavour non-diagonal final states $\tilde
e\tilde\mu$, $\tilde e\tilde\tau$ and $\tilde \mu\tilde\tau$, forbidden in the
MSSM. These processes also give indirect information about neutrino mixings
since they depend on the same couplings as the Majorana mass terms of the
right-handed neutrinos.
