We present the first extraction of the transversity distribution based on the\nglobal analysis of pion-pair production in deep-inelastic scattering and in\nproton-proton collisions with one transversely polarized proton. The extraction\nrelies on the knowledge of di-hadron fragmentation functions, which are taken\nfrom the analysis of electron-positron annihilation data. For the first time,\nthe chiral-odd transversity is extracted from a global analysis similar to what\nis usually done for the chiral-even spin-averaged and helicity distributions.\nThe knowledge of transversity is important among other things for detecting\npossible signals of new physics in high-precision low-energy experiments.\n
