Title: Recent theoretical results for 0νββ-decay including R0νECEC and 0νββM

The most recent (2015) results for 0νββ nuclear matrix elements in the interacting boson model (IBM-2) with light and heavy neutrino exchange, including R0νECEC, are given for all nuclei of interest from {sup 48}Ca to {sup 238}U. Predictions for half-lives and limits for average neutrino mass are also made. Possible additional scenarios, such as Majoron emission, is also discussed.
