# Testing B-violating signatures from Exotic Instantons in future colliders

## TL;DR

This paper explores how exotic stringy instantons could lead to baryon number violation detectable at future high-energy colliders, with potential signals in six-quark interactions and Lambda-antiLambda transitions.

## Contribution

It proposes a novel connection between exotic instantons and baryon-violating signatures, analyzing their detectability at colliders beyond the LHC, especially at energies around 20-100 TeV.

## Key findings

- Lambda-antiLambda transitions require extremely high luminosity to detect.
- Exotic instanton-induced six-quark interactions could be tested at future colliders like SppC.
- Model is compatible with existing neutron-antineutron and meson decay bounds.

## 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 $\Lambda-\bar{\Lambda}$ 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 $NN\rightarrow \pi\pi,KK$. On the other hand, (exotic) instanton-induced six quark interactions can be tested in near future high-energy colliders beyond LHC, at energies around $20-100\, \rm TeV$. 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 $NN\rightarrow \pi\pi,KK$ bounds.
