of small mass of the pseudoscalar mesons (Goldstone bosons). In Refs. [@hidden1; @hidden2; @hidden4; @Yama; @hideko; @derafael], and particularly in Refs. [@Yama; @derafael], one can see that the terms of the chiral Lagrangians can be obtained from the exchange of vector mesons in the local hidden gauge. Ref. [@derafael] also shows that the consideration of vector mesons is necessary to implement vector meson dominance. Both in Ref. [@derafael] and Ref. [@Yama] it is also shown that the formalisms using antisymmetric tensors for the vector mesons, and the use of ordinary vector fields in the local hidden gauge are equivalent. If one specifies to the meson-baryon Lagrangians [@ecker], it is easy to show that the exchange of vector mesons gives rise exactly to the lowest order chiral Lagrangian in the limit of small momentum transfer compared to the vector meson mass. All this occurs within SU(3), involving $u$, $d$, $s$ quarks. The local hidden gauge in the unitary gauge in SU(3), can be found in Ref. [@derafael] and with more detail in Ref. [@hideko]. The extrapolation to SU(4) to incorporate $c$ quarks, or even higher with $b$ quarks, is not straightforward, as one cannot invoke the Goldstone boson character for $D$
