摘要：
Classical arguments are used to show that the decay D(s)+ --> pnBAR could be an indicator of whether or not the axial current is conserved at large q2. Keeping the pi(1300) as the most relevant contribution to the form factor associated to the four-divergence of the axial constant we find indications that the decay BR(D(s)+ --> pnBAR) could be as large as approximately 1%.
