We discuss a low energy e+e− collider for production of the not yet observed (μ+μ−) bound system (dimuonium). Collider with large crossing angle for e+e− beams intersection produces dimuonium with non-zero momentum; therefore, its decay point is shifted from the beam collision area providing effective suppression of the elastic e+e− scattering background. The experimental constraints define subsequent collider specifications. We show preliminary layout of the accelerator and obtained main parameters. High luminosity in chosen beam energy range allows to study π± and η-mesons.

We report the integral elastic cross section for low-energy electron scattering by CS2 molecules. To perform our calculations we used the Schwinger multichannel method with pseudopotentials.We have found, in a static-exchange calculation, a shape resonance around 1 eV that belongs to the Π u symmetry.With the inclusion of polarisation effects only in that symmetry, we show that the resonance becomes a bound state. This result is in agreement with other results available in the literature.

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 ~ me = 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 [Formula: see text]. This is because the formation of superconducting (preconfining) SU(2) hot-spots "steals" a large fraction of [Formula: see text] 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 ~ me and photons of energy ~ 2me.
