From Pentaquarks to Dibaryons in Lambda_b(5620) decays

Abstract

Pentaquarks and dibaryons are natural possibilities if diquarks are used as the building blocks to assemble hadrons. In this short note, motivated by the very recent discovery of two pentaquark states, we highlight some possible channels to search for dibaryons in Lambda_b(5620) decays.
