Some of most spectacular light-induced phenomena\, such as superconducting-like phases\, transient charge density wave ordering\, and excitonic condensation\, are found to occur in materi als dominated by strong electronic correlations with a large susceptibilit y to external stimuli. A major need towards developing a microscopic under standing of these states of matter is the capability to directly measure t heir transient electronic dynamics and effective interactions.\n\nIn this talk\, I will show how novel ultrafast x-ray spectroscopic methods\, such as time-resolved x-ray absorption (trXAS) and time-resolved resonant inela stic x-ray scattering (trRIXS)\, enable tackling these questions with unpr ecedented detail [1]. I will particularly focus on light-driven Mott insul ators\, which are key to the emergence of light-induced superconductivity and are theoretically argued to host other exotic ordering phenomena upon photoexcitation\, such as h-pairing condensation. I will discuss how trXAS allows to accurately determine transient effective electronic interaction s in 1D and 2D copper oxides\, and how we can fully reconstruct the driven many-body state from the transient absorption spectrum [2\,3]. Further\, I will discuss how advances in trRIXS [1\,4\,5] enable mapping the excitat ion spectrum of the driven state\, and the implications of these experimen ts for the realization of new light-induced states in photoexcited Mott in sulators.\n\n[1] M Mitrano & Y.
