Query: Detection of SUSY in the Stau-Neutralino Coannihilation Region at the
  LHC   We study the feasibility of detecting the stau neutralino
(stau_1-neutralino_1)coannihilation region at the LHC using tau leptons. The
signal is characterized by multiple low energy tau leptons from
neutralino_2-->tau stau_1-->tau tau neutralino_1 decays, where the stau_1 and
neutralino_1 mass difference (Delta M) is constrained to be 5-15 GeV by current
experimental bounds including the bound on the amount of neutralino cold dark
matter. Within the framework of minimal supergravity models, we show that if
hadronically decaying tau's can be identified with 50% efficiency for visible
pt >20 GeV the observation of such signals is possible in the final state of
two tau leptons plus large missing energy and two jets. With a gluino mass of
830 GeV the signal can be observed with as few as 3-10 fb^-1 of data (depending
on the size of Delta M). Using a mass measurement of the tau pairs with 10
fb^-1 we can determine dM with a statistical uncertainty of 12% for Delta M =
10 GeV and an additional systematic uncertainty of 14% if the gluino mass has
an uncertainty of 5%.
