      abstract     = {X-ray cavity quantum optics with inner-shell transitions
                      has been limited by the spectral overlap between resonant
                      and continuum states. Here, we report the first experimental
                      demonstration of cavity-controlled core-to-core resonant
                      inelastic x-ray scattering (RIXS). We suppress the
                      absorption-edge effects by monitoring the RIXS profile,
                      thereby resolving the resonant state from the overlapping
                      continuum. We observe distinct cavity-induced energy shifts
                      and cavity-enhanced decay rates in the
                      2⁢𝑝⁢3⁢𝑑RIXS spectra of WSi$_2$. These effects,
                      manifesting as stretched or shifted profiles in the RIXS
                      planes, enable novel spectroscopic applications via
                      cavity-controlled core-hole states. Our results establish
                      core-to-core RIXS as a powerful tool to manipulate
                      inner-shell dynamics in x-ray cavities, offering new avenues
                      for integrating quantum optical effects with x-ray
                      spectroscopy.},
