Physicists discover new sub-atomic particle using Large Hadron Collider

  1. Physicists running experiments using the Large Hadron Collider (LHC) have confirmed the existence of a new class of sub-atomic particles called pentaquarks.

    The existence of sub-atomic particles called quarks was first theorized in the 1960s by physicists Murray Gell Mann and George Zewig. As Gizmodo explains, quarks come together to form larger particles – such as protons or neutrons – in groups of three.

    Physicists speculated that quarks can form other entities as well, like the proposed pentaquark which was believed to consist of four quarks and an anti-quark.

    To confirm its existence, physicists observed how a sub-atomic particle called Lambda b decayed into three other particles inside the LHC. The team took note of a transition state in which two previously unidentified particles – Pc(4450)+ and Pc(4380)+ – were identified.

    LHC physicist Tomasz Skwarnicki said they examined all possibilities and conclude that they can only be explained by pentaquark states.

    Gary Wilkinson, a spokesperson for LHCb, said the pentaquark is not just any new particle. It represents a way to aggregate quarks, namely the fundamental constituents of ordinary protons and neutrons, in a pattern that has never been observed before in over 50 years of experimental searches.

    During the mid-2000s, multiple scientific teams claimed to have detected pentaquarks. Unfortunately for the scientific community, subsequent experiments showed those results were actually fluctuations and not real signals like the ones seen from the LHC.

    The team has submitted their findings to the Physical Review Letters journal for those wishing to dig deeper.

    I would like to postulate existence of a particle, aptly called "ops! particle", as the very last discovery by every civilized world, hence the name.

    I'm not yet ready to describe its full set of properties, except to say that it is a very mean one, and definitively not as funny as pentaquarks, while looking at the article's picture, to assume that the new particle must look like a meat and two wedges. Otherwise, what are they laughing at?

    If the first image is any indication of what it looks like - that is just bollocks! And evidently that's enough for a bunch of nerds to have so much fun. Why not? It's a 13 billion installation that costs in excess of 100 million a year to run, and it makes bollocks. Tax payer's money well spent.

    P.S. If you take in of these seriously, they've got a jacket with your name on it ;)

    I might would get excited, if I understood how this is an actual advancement.

    Hmm, you should probably keep in mind that Gizmodo is not a credible source. It is Gawker after all.
     
  6. By using a such LHC machine is possible to build different structures of particles, the problem is to found the rule of organization inside. The correct news isn't to say it was discovered a new particle, it is to say it was "builded" a new particle as by using the collision pp energy by extraction from the vacuum the quarks and the gluons, see my works on Research Gate.

    No one should ever say "builded", try the word "built".
