The particle involved in the experiment claiming superluminal speed was the neutrino. The results were later attributed to experimental errors, specifically a faulty cable connection in the GPS timing system and an oscillator issue, and the initial claim was retracted.
In the recent past, a fundamental particle has been claimed to be experimentally observed, at a European Laboratory in Geneva, to travel at a speed greater than that of light in vacuum. The name of the particle is
