Description
In this talk I will review recent progress in the field of event shapes with massive particles. I will present "massive" schemes, emphasising their impact on the sensitivity to quark masses, and will show results for fixed-order and resummed computations up to $\rm N^2LL+ \mathcal{O}(\alpha_s)$ accuracy. For the 2-jettiness observable, cross sections at $\rm{N^3LL} + \mathcal{O}(\alpha_s^2)$ precision will be presented in the peak region, where the one is most sensitive to the top quark mass. If time permits, I will briefly cover exact computations in the large-$\beta_0$ limit of the relevant EFT matrix elements.
