Abstract

We discuss possible implications of Exotic Stringy instantons for Baryon-violating signatures in future colliders. In particular, we discuss high-energy quarks collisions and ΛΛˉ\Lambda-\bar{\Lambda} transitions. In principle, ΛΛˉ\Lambda-\bar{\Lambda} 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 NNππ,KKNN\rightarrow \pi\pi,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 20100TeV20-100\, \rm TeV. Super proton-proton collider (SppC) is 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 NNππ,KKNN\rightarrow \pi\pi,KK bounds.
