1. j particle

   The J/ψ (J/psi) meson or psion is a subatomic particle, a flavor-neutral meson consisting of a charm quark and a charm antiquark. Mesons formed by a bound state of a charm quark and a charm anti-quark are generally known as "charmonium". The J/ψ is the most common form of charmonium, due to its spin of 1 and its low rest mass. The J/ψ has a rest mass of 3.0969 GeV/c2, just above that of the ηc (2.9836 GeV/c2), and a mean lifetime of 7.2×10−21 s. This lifetime was about a thousand times longer than expected.Its discovery was made independently by two research groups, one at the Stanford Linear Accelerator Center, headed by Burton Richter, and one at the Brookhaven National Laboratory, headed by Samuel Ting of MIT. They discovered they had actually found the same particle, and both announced their discoveries on 11 November 1974. The importance of this discovery is highlighted by the fact that the subsequent, rapid changes in high-energy physics at the time have become collectively known as the "November Revolution". Richter and Ting were awarded the 1976 Nobel Prize in Physics.

1. j particle

   A J particle is a term used in particle physics usually referring to the J/Psi Particle, which is a subatomic particle that consists of a charm quark and a charm antiquark. It was independently discovered by teams led by Samuel Ting at the Brookhaven National Laboratory and Burton Richter at Stanford Linear Accelerator Center in 1974. This type of particle is also known as a meson and is part of the hadron family in quantum physics.

Examples of j particle in a Sentence

1. Harold Wimmer:

   The nation has known for some time that long-term exposure to particle pollution can worsen symptoms of lung disease, increase susceptibility to lung infection, trigger heart attack and stroke, and can even cause lung cancer and premature death, this new research from Harvard University now links particle pollution exposure to a dramatically higher death rate from Covid-19.

2. Vanna Bonta:

   How do we define consciousness, or what has been called the human soul or the spirit, if it can't be quantified as matter or a particle? ... it can be quantified or observed just by a process of elimination.

3. Gabriella Sciolla:

   Z-prime is much heavier than a Z particle, something like tens of times the mass, z-prime can decay in a very simple way that yields two very energetic muons, which are basically heavier versions of electrons. If we can detect the muon signature of Z-prime, that would support models that predict the existence of Z-prime.

4. Tom Giblin:

   When were studying the early universe, what were really doing is a particle experiment at very, very high temperatures, the transition from the cold inflationary period to the hot period is one that should hold some key evidence as to what particles really exist at these extremely high energies.

5. Dante Lauretta:

   Among Bennus many surprises, the particle ejections sparked our curiosity, and weve spent the last several months investigating this mystery, this is a great opportunity to expand our knowledge of how asteroids behave.
