BURSTS OF LOW-ENERGY ELECTRON-POSITRON PAIRS IN TeV-RANGE COLLIDER PHYSICS

In this letter we investigate the possible emission of low-energy electron neutrinos and electron-positron pairs of anomalously large multiplicity in close-to-central pp collisions at LHC. The scenario is based on confining SU(2) Yang-Mills dynamics of Hagedorn temperature similar to m(e) = 511 keV being responsible for the emergence of the lightest lepton family and the weak interactions of the Standard Model. Although cut off by LHC's detectors these electron-positron bursts would be seen indirectly by a large defect energy and thus an anomalously strong decrease of events with interesting high-energy secondaries for increasing root s. This is because the formation of superconducting (pre-confining) SU(2) hot-spots "steals" a large fraction of root s subsequently transferring it to a thermal spectrum of electron neutrinos, electrons, and positrons liberated through evaporation. We thus propose the detection of electrons and positrons of kinetic energy similar to m(e) and photons of energy similar to 2m(e).
