Abstract
The role of the triangle mechanism in the decay processes
and
is probed. In these processes, the triangle singularity appears from the decay of
into
, and then, ϕ decays into
and
merged into
or
, which finally decay into
and
, respectively. We find that this mechanism leads to a triangle singularity around
and gives sizable branching fractions
and
. This investigation can help us obtain the information of the scalar meson
or
.
