AbstractWe consider baryon-number-violating nucleon and dinucleon decays to leptonic final states in the context of a left-right symmetric (LRS) model with large extra dimensions. Specifically, we study (a) nucleon to trilepton decays with $$\varDelta B=-1$$ Δ B = - 1 and $$\varDelta L=-3$$ Δ L = - 3 , and (b) dinucleon to dilepton decays with $$\varDelta B=-2$$ Δ B = - 2 and $$\varDelta L=-2$$ Δ L = - 2 . In the LRS model, $$B-L$$ B - L is gauged and is spontaneously broken by a Higgs vacuum expectation value $$v_R$$ v R , which characterizes the scale at which processes violating $$B-L$$ B - L occur. We show that together with the lower bound on $$v_R$$ v R from experimental limits on n-$${\bar{n}}$$ n ¯ oscillations, constraints from searches for other nucleon decay modes imply sufficient suppression of these nucleon to trilepton and dinucleon to dilepton decay modes in this model to agree with experimental bounds.
