Elastic ${\pi }^{+}p$ and ${\pi }^{+}{\pi }^{+}$ scattering at LHC

Abstract

We discuss the possibility of measuring leading neutron production at the LHC. These data could be used to extract from it ${\pi }^{+}p$ and ${\pi }^{+}{\pi }^{+}$ cross-sections. In this note we give some estimates for the case of elastic cross-sections and discuss related problems and prospects.
