Query: Collinearity approximations and kinematic shifts in partonic shower
  algorithms   We study kinematic effects due to the approximation of on-shell, collinear
partons in shower Monte Carlo event generators. We observe that the
collinearity approximation, combined with the requirements of energy-momentum
conservation, gives rise to a kinematic shift, event by event, in longitudinal
momentum distributions. We present numerical results in the case of jet and
heavy flavor production processes measured at the LHC.
