Query: Two-body hadronic decay of $K^{+}$ in the presence of a circularly
  polarized laser field   In this study, we have investigated the two-body hadronic decay of the
charged kaon, $ K^{+}\rightarrow\pi^{+}+\pi^{0} $, in the presence of a laser
field with circular polarization. We have derived, by analytical techniques,
the laser-assisted decay width and the branching ratio of the charged kaon
decay via the two-body hadronic channel. We have also taken into consideration
the impressive results obtained for the laser-assisted charged kaon decay via
the leptonic mode in order to understand more clearly the effect of the laser
field on the quantities related to the charged kaon decay such as the decay
width, the branching ratio and lifetime. A precise comparison of the ratios of
hadronic to muonic decay in the presence of the laser field is made to show
that the hadronic mode becomes slightly more important by increasing the laser
field intensity.
