Contribution

It introduces a novel detector design that is scalable and suitable for shallow water environments for proton decay searches beyond current limits.

Findings

Potential to detect proton decay with lifetime beyond 10^35 years

Scalable design allows for larger detector volumes in shallow water

Enhanced sensitivity compared to existing detectors

Abstract

In this report, we will show a detector which can be used to search for proton decay in the lifetime region beyond 10$^{35}$ years. We will briefly review the current experimental status and discuss the sensitivity of the future proton decay detectors, and we specifically present a possibility of a scalable multi-megaton water Cherenkov detector immersed in the shallow water.
