  text: 'A new window is opening in high-energy astronomy: X-ray polarimetry. With
    many missions currently under development and scheduled to launch as early as
    2021, observations of the X-ray polarization of accreting X-ray pulsars will soon
    be available. As polarization is particularly sensitive to the geometry of the
    emission region, the upcoming polarimeters will shed new light on the emission
    mechanism of these objects, provided that we have sound theoretical models that
    agree with current spectroscopic and timing observation and that can make predictions
    of the polarization parameters of the emission. We here present a new model for
    the polarized emission of accreting X-ray pulsars in the accretion column scenario
    that for the first time takes into account the macroscopic structure and dynamics
    of the accretion region and the propagation of the radiation towards the observer,
    including relativistic beaming, gravitational lensing, and quantum electrodynamics.
    In this paper, we present all the details of the model, while in a companion paper,
    we apply our model to predict the polarization parameters of the bright X-ray
    pulsar Hercules X-1.'
