Re: Tevatron accelerator yields hints of new particle
Reconstruction (adding the daughter particles to work out the parent particle) at these powerful all purposes detectors are is not fantastically accurate, you get plenty of false candidates. To work out if you have found something real you plot all the results in a histogram and something genuine should leave a "bump".
With statistics you can work out the likelihood that what you are looking at is a genuine bump or just randomness producing a bump.
