Query: Luminosity Measurement Method for LHC: The theoretical precision and the
  experimental challenges   This is the first of the series of papers which present a precision method of
the day-by-day monitoring of the absolute LHC luminosity. The method is based
on the measurement of the rate of coplanar lepton pairs produced in peripheral
collisions of the beams' particles. In the present paper we evaluate the
modeling precision of the lepton pair production processes in proton-proton
collisions, optimize the measurement region to achieve better than 1% accuracy
of the predicted rates, and discuss the experimental challenges to filter out
the luminosity monitoring lepton pairs at LHC.
