Description
I will review gravitational form factors and their connection to the energy-momentum tensor, with emphasis on their pressure interpretation and conformal symmetry. I will then discuss the conformal window and some (old) open questions concerning the transition between conformal and chirally broken phases. If time permits, I will illustrate these ideas with applications to my own work, including the interpretation of the $\sigma$ meson as a dilaton—the pseudo-Goldstone boson associated with spontaneously broken conformal symmetry.
