Testing B-violating signatures from Exotic Instantons in future colliders

Understand

We discuss possible implications of Exotic Stringy instantons for Baryon-violating signatures in future colliders.

• In particular, we discuss high-energy quarks collisions and $\Lambda-\bar{\Lambda}$ transitions.
• In principle, $\Lambda-\bar{\Lambda}$ 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 $NN\rightarrow \pi\pi,KK$.
