    Transverse momentum-dependent heavy-quark fragmentation at next-to-leading order

    The transverse momentum-dependent fragmentation functions (TMD FFs) of heavy (bottom and charm) quarks, which we recently introduced, are universal building blocks that enter predictions for a large number of ...

    Transverse momentum distributions of heavy hadrons and polarized heavy quarks

    We initiate the study of transverse momentum-dependent (TMD) fragmentation functions for heavy quarks, demonstrate their factorization in terms of novel nonperturbative matrix elements in heavy-quark effective...
