Testing B-violating signatures from exotic instantons in future colliders
Résumé
We discuss possible implications of exotic stringy instantons for baryon-violating signatures in future colliders. In particular, we discuss high-energy quark collisions and transitions. In principle, the process can be probed by high-luminosity electron-positron colliders. However, we find that an extremely high luminosity is needed in order to provide a (somewhat) stringent bound compared to the current data on NN --> pipi,KK. On the other hand, (exotic) instanton-induced six-quark interactions can be tested in near future high-energy colliders beyond LHC, at energies around 20--100 TeV. The Super proton-proton Collider (SppC) would be capable of such measurement given the proposed energy level of 50--90 TeV. Comparison with other channels is made. In particular, we show the compatibility of our model with neutron-antineutron and NN --> pipi,KK bounds.
