LHC double heavy particle to shine light on strong force

Scientists have detected a new particle at the Large Hadron Collider at Cern.

The discovery will help researchers learn more about the so-called "strong force" which holds the centres of atoms together.

The existence of the new particle was theoretically predicted but this is the first time it has been identified.

The details of the Xi-cc++ particle were presented at a high-energy physics conference in Venice.

[...] This is the first time that researchers have confirmed the existence of [a particle] with two heavy quarks. According to Prof Guy Wilkinson of Oxford University, there is an intriguing difference between the new particle and the ones that have been discovered before.

"In contrast to other particles of this type, in which the three quarks perform an elaborate dance around each other, a particle with two heavy quarks is expected to act like a planetary system, where the heavy quarks are like two stars orbiting one around the other, with the lighter quark orbiting around this binary system."

    I wonder what could be found with equipment that is able to sense probability densities?

    The amplitudes are mathematical abstractions - you don't detect them, you calculate them.
    Anything you detect has a near 100% chance of being what you detected (hence the almost paradox that if you examine something often enough, it will never change state. Weeping angels, and all that...)
