Resumo
The nature of the recently discovered Zc and Zb structures is intriguing. Their charge forces its minimal quark content to be Q¯ Qq¯ q (where Q = {c,b} and q = {u,d}). In this work we perform a molecular coupled-channels calculation of the IG(JPC) = 1+(1+−) charm and bottom sectors in the framework of a constituent quark model which satisfactorily describes a wide range of properties of (non-)conventional hadrons containing heavyquarks. Alltherelevantchannelsareincludedforeachsector, i.e.: The D(∗)¯ D∗+h.c., πJ/ψ and ρηc channels for the Zc and B(∗)B∗ and Υ(nS)π (n = 1,2,3) channels for the Zb analysis. Possible structures of these resonances will be discussed.
