Query: High Momentum Transfer HERA Events and pQCD at High x   We compare data on the proton structure function from SLAC experiments in the
range of x between 0.7 and 0.97 in and near the resonance region with previous
empirical fits to Deep Inelastic Scattering and with calculations from parton
distribution functions. The data is in rough agreement with the empirical fits,
but is an order of magnitude higher than the pQCD calculations at the highest
x. This compares with the two orders of magnitude increase in the quark
distributions at high x which seem to be necessary to explain the HERA high
momentum transfer events.
