M. Arneodo et al., A SPECTROMETER TO STUDY ELASTIC AND DIFFRACTIVE PHYSICS AT LHC, International journal of modern physics A, 13(23), 1998, pp. 3993-4009
The possibility to study elastic and diffractive physics in pp collisi
ons at LHC is discussed. For this purpose we have considered detectors
close to the beam in conjunction with the magnetic elements of the ac
celerator to provide a high precision spectrometer for very forward fi
nal state protons. The geometrical acceptance is given and the momentu
m resolution is calculated for different spatial resolution detectors.
