Modified parton distributions and the HERA high-Q^2 anomaly
A recent proposal seeks to explain the anomaly in the HERA high-Q^2 neutral current e^+p data by modifying the parton distribution functions at moderate-to-high-x and large Q^2. We investigate the consequences of this proposal for the HERA high-Q^2 data itself, in the neutral current e^-p channel an...

| description | A recent proposal seeks to explain the anomaly in the HERA high-Q^2 neutral current e^+p data by modifying the parton distribution functions at moderate-to-high-x and large Q^2. We investigate the consequences of this proposal for the HERA high-Q^2 data itself, in the neutral current e^-p channel and especially in the charged current e^\pm p channels. We find that there are striking signatures in the charged current which already serve to rule out many possibilities, including the (symmetric) intrinsic charm hypothesis. For those not ruled out, interesting signals are predicted in e^-p scattering. |
