چکیده انگلیسی
In our earlier paper [1] we have proposed a new luminosity measurement method for the LHC collider. It is based on the detection of lepton pairs produced in the peripheral collisions of the LHC beam particles and allows to reach better than 1% accuracy of the theoretical control of the event rate. In order to implement this method a new, specialized luminosity detector must be incorporated within the fiducial volume of one of the existing LHC detectors. In this paper the requirement studies for such a detector are presented. They are driven, almost exclusively, by its capacity to identify, within the level 1 trigger latency of the host detector, the bunch crossings with exclusive, coplanar pairs of opposite charge particles. It is shown that a tracking detector with the azimuthal hit resolution of 2Â mrad allows us to reduce the rate of background events to the requisite O(1kHz) level while retaining a sufficiently large fraction of the signal events for the precise luminosity measurement.
