| Abstract: | We explore the possibility that the excess neutral and charged current events seen by the H1 and ZEUS Collaborations at HERA at large x and Q2 could arise from a hard charm component of the nucleon. While the symmetric intrinsic charm hypothesis is unable to account for the HERA anomaly, a non-symmetric charm distribution generated non-perturbatively, for which c̄ is much harder than c, can produce significant enhancement of cross sections at the HERA kinematics. © 1997 Elsevier Science B.V. |
