Abstract

The nature of the recently discovered Zc and Zb structures is intriguing. Their charge forces its minimal quark content to be QˉQqˉq (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 heavy quarks. All the relevant channels are included for each sector, i.e.: The D()ˉD+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
