We detect an electron beam that only appears with few-cycle pulses (< 10 fs) and large plasma scale lengths ($L > \\lambda_0$). Numerical simulations, in agreement with the experiments, reveal that these electrons are accelerated by a laser wakefield. Plasma waves are indeed resonantly excited by the few-cycle laser pulses in the near-critical-density region of the plasma. Electrons are then injected by ionization into the plasma waves and ac","authors_text":"A. Vernier, F. B\\\"ohle, J. Faure, L. Videau, M. Bocoum, N. Za\\\"im, R. Lopez-Martens, S. Haessler, X.
