- The majority of research and data analysis is computerized.
- The new particle discovered is in the excited state.
- CERN uses five-sigma for the experiment purposes.
A new neural network has been developed by Russian researchers. It became possible while analyzing data from the world’s large Hadron collider. The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. The Collider has been operational, since 2009.
The LHC is a project of the European Organization for Nuclear Research (CERN). It is located outside of Geneva. Switzerland. During the experiment the LHC is sending beams of protons and ions at a velocity approaching the speed of light. Researchers then observe them colliding and record the data. New particles are being discovered during the process. A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. An ion is an atom or molecule that has a net electrical charge. Since the charge of the electron is equal and opposite to that of the proton, the net charge of an ion is non-zero due to its total number of electrons being unequal to its total number of protons.
Furthermore, the new particle discovery is a surprise and it was never expected to be found. This is the first observation of excited Ω−b.

What does it mean?
This is the omega baryons in an excited state. The omega baryons are a family of subatomic Hadron (a baryon) particles that are represented by the symbol Ω and are either neutral or have a +2, +1 or −1 elementary charge. They are baryons containing no up or down quarks. The new particle can be analyzed as having very unique charm. Also, the particle energy is bigger than anyone thought possible for the omega-baryon. Hence, the state of excitement and why it is such an important new finding in physics.
A majority of research is now computerized. The researchers are using algorithms to analyze large initial data and narrow the data that will be analyzed further. computers also allow large amounts of data to be processed at record speeds.
The new particle has been found during four different events as reported by the Russian researchers. The golden standard to be sure is five-sigma. The Greek letter sigma is used to represent standard deviation. Standard deviation measures the distribution of data points around a mean, or average, and can be thought of as how “wide” the distribution of points or values is.
A three sigma means the probability is only a fraction of a percentage. The five-sigma corresponds to a p-value, or probability, of 3×10-7, or about 1 in 3.5 million. This is not the probability that the Higgs boson does or doesn’t exist; rather, it is the probability that if the particle does not exist, the data that CERN scientists collected in Geneva, Switzerland, would be at least as extreme as what they observed.
The LHC continues to bring exiting findings and very interesting discoveries in the world of physics.
