The behavior of the corresponding branching ratios are then analyzed within the type-II THDM in a region of the parameter space around the alignment limit and still consistent with experimental data. It is found that the $A\\to Z\\gamma\\gamma$ branching ratio is only relevant when $m_A>m_H+m_Z$, but it is negligible otherwise.
