Do leptoquarks manifest themselves in ultra-high energy neutrino interactions?

Abstract

It is assumed that neutrino-nucleon scattering at ultra-high energies effectively proceeds through excitations of leptoquarks in neutrino-quark subprocesses. This approach reproduces the behavior of the energy dependence of the ultra-high energy neutrino-nucleon scattering cross sections and allows to estimate masses as well as the decay widths of the involved leptoquarks. For instance, this leads to the leptoquark mass $1353\pm 230$ GeV in a way independent on the leptoquark quantum numbers. The discovery potential of the LHC for the leptoquarks is evaluated.
