Processes that violate baryon number, most notably proton decay and $n\bar n$ transitions, are promising probes of physics beyond the Standard Model (BSM) needed to understand the lack of antimatter in the Universe. To interpret current and forthcoming experimental limits, theory input from nuclear matrix elements to UV complete models enters. Thus, an interplay of experiment, effective field theory, lattice QCD, and BSM model building is required to develop strategies to accurately extract information from current and future data and maximize the impact and sensitivity of next-generation experiments. Discussions to foster the exchange among the different communities, including the identification of promising search strategies and channels, took place during the workshop ``INT-25-91W: Baryon Number Violation: From Nuclear Matrix Elements to BSM Physics,'' see arXiv:2504.16983 for a more detailed write-up of the main results and discussions as well as extended abstracts for all presentations.
