On the problem of the eta→π0γγ decay
Description
In the framework of the chiral quantum field theory it is shown that the process eta→π0γγ is related to the process eta→π+π-π0 and can not proceed via the baryonic loops like the decay eta→γγ. The theoretical estimates for the width of this decay are in sharp disagreement with the experimental data available at present
