abstract
We have searched for proton decay via $p \rightarrow \nu K^{+}$ using Super-Kamiokande data from April 1996 to February 2013, 260 kiloton$\cdot$year exposure in total. No evidence for this proton decay mode is found. A lower limit of the proton lifetime is set to $5.9 \times 10^{33}$ years at 90% confidence level.

Introduces echo signatures from vector long-lived particles in nucleon decay, showing high geometric acceptance up to 80% in Super-K, Hyper-K and JUNO for a range of decay lengths.
Extended SU(5) GUT with 45 Higgs and DFSZ axion uses one-loop unification to correlate proton decay modes with axion mass and couplings.
Multiple vector-like fermions in SU(5) GUT raise the unification scale to about 10^15.5 GeV, suppress proton decay operators via multiplet admixtures, and relax rigid Yukawa relations to better match observed fermion masses.
The authors use Adam optimization over a 33-dimensional parameter space in an SU(5) model with 45 and 45bar Higgs representations to search for Yukawa values that make the proton lifetime exceed the Super-Kamiokande bound of 5.9e33 years.
