Description
In the talk, I will summarize our recent works on the study of baryon-number-violating nucleon decay modes, either with or without a new light particle in the final state. In light of the current and upcoming neutrino expriments, a solid theoretical description of all possible kinematically allowed decay modes is urgent. We work within the low energy effective field theory (LEFT) plus chiral perturbation theory (ChPT) framework, and construct the relevant LEFT operators and their corresponding hadronic chiral counterparts. Within the chial framework, we formulate the general expressions of the nucleon decay widths and analyze their characteristic experimnetal signatures, which facilitate experimental searches for those nucleon decays.
