SDO/HMI observations reveal a class of solar flares with substantial energy and momentum impacts in the photosphere, resulting in white-light emission and helioseismic response (sunquakes). Previous radiative hydrodynamic modeling using the RADYN code showed that such impacts could not be explained in the framework of the standard flare model with electron beam heating. One of the possibilities to explain the observed white-light emission and sunquakes is to consider additional heating mechanisms involved in solar flares, for example, Alfvén wave heating and heating by the proton beams. In this work, we analyze the single-loop RADYN proton beam simulations for a wide set of beam parameters. Using the output of the RADYN models, we calculate synthetic HMI-line Stokes profiles and line-of-sight (LOS) observables as well as the 3D helioseismic response and compare them with the corresponding observed characteristics. The initial results show that the RADYN models with proton beam heating are substantially closer to the HMI observations than the standard electron-beam thick-target models.
