The nucleon transverse quark spin densities are presented. The densities are extracted from the unpolarized and transversity generalized form factors using three Nf = 2 + 1 + 1 twisted mass fermion ensembles simulated with physical quark masses. The results obtained for three lattice spacings are extrapolated to the continuum limit directly at the physical pion mass. The isovector tensor anomalous magnetic moment is determined to be κT = 1.051(94), which confirms a negative and large Boer-Mulders function, h⊥1 , in the nucleon.
