  Core-collapse supernovae are a useful laboratory to probe the nature of
exotic particles. If axionlike particles (ALPs) are produced in supernovae,
they can affect the transfer of energy and leave traces in observational
signatures. In this work, we present results from two-dimensional supernova
models including the effects of the production and the absorption of ALPs that
couple with photons. It is found that the additional heating induced by ALPs
can enhance the diagnostic energy of explosion, E_diag. For example, for
moderate ALP-photon coupling, we find explosion energies ~0.6*10^51 erg
compared to our reference model without ALPs of ~0.4*10^51 erg in the first
~0.5 s postbounce explored in this work. Our findings indicate that when the
coupling constant is sufficiently high, the neutrino luminosities and mean
energies are decreased because of the additional cooling of the proto-neutron
star via ALPs. The gravitational wave amplitude is also reduced because the
mass accretion on the proto-neutron star is suppressed. Although the ALP-photon
coupling can foster explodability, including enhancing the explosion energy
closer to recent observations, more long-term simulations in spatially
three-dimension are needed to draw robust conclusions
