Faster than light

The article entitled "Measurement of the neutrino velocity with the OPERA detector in the CNGS beam" published in arXiv.org e-Print archive http://arxiv.org/abs/1109.4897 by Adam et al has generated a lot of attention it talks about "An early arrival time of CNGS muon neutrinos with respect to the one computed assuming the speed of light in vacuum of (60.7 ± 6.9 (stat.) ± 7.4 (sys.)) ns was measured. This anomaly corresponds to a relative difference of the muon neutrino velocity with respect to the speed of light (v-c)/c = (2.48 ± 0.28 (stat.) ± 0.30 (sys.)) ×10-5." In layman terms it says that the neutrinos travel faster than light.
Science now (http://www.wired.com/wiredscience/2011/09/neutrinos-faster-than-light/) says that "If it’s true, it will mark the biggest discovery in physics in the past half-century: Elusive, nearly massless subatomic particles called neutrinos appear to travel just faster than light, a team of physicists in Europe reports. If so, the observation would wreck Einstein’s theory of special relativity, which demands that nothing can travel faster than light.
It must be noted that the authors say "Despite the large significance of the measurement reported here and the stability of the analysis, the potentially great impact of the result motivates the continuation of our studies in order to investigate possible still unknown systematic effects that could explain the observed anomaly. We deliberately do not attempt any theoretical or phenomenological interpretation of the results.
