  "abstract": "Context: Supernova (SN) 2023ixf is among the most nearby Type II SNe in the last decades. As such, there is a wealth of observational data of both the event itself and of the associated object identified in pre-explosion images. This allows to perform a variety of studies that aim at determining the SN properties and the nature of the putative progenitor star. Modelling of the light curve is a powerful method to derive physical properties independently of direct progenitor analyses. Aims: To investigate the physical nature of SN 2023ixf based on hydrodynamical modelling of its bolometric light curve and expansion velocities during the complete photospheric phase. Methods: A grid of one dimensional explosions was calculated for evolved stars of different masses. We derived properties of SN 2023ixf and its progenitor by comparing our models with the observations. Results: The observations are well reproduced by the explosion of a star with zero age main sequence mass of f $M_\\mathrm{ZAMS} = 12 M_\\odot$ , an explosion energy of $1.2 \\times 10^{51}$ erg, and a nickel production of 0.05M . This indicates that SN 2023ixf was a normal event. Our modelling suggests a limit of $M_\\mathrm{ZAMS} < 15 M_\\odot$ and therefore favours the low mass range among the results from pre-explosion observations.",
