charm quark

The D mesons are the lightest particle containing charm quarks.

The charm quarks were observed bound with charm antiquarks in mesons.

Some of the hadrons containing charm quarks include:

Charm quarks or c quarks are the third most massive of the six quarks.

In this case, it was examining the decay of particles that contain charm quarks and antiquarks, called D mesons.

Charm quarks are found in hadrons, which are subatomic particles made of quarks.

All bottom quarks will decay into charm quarks or up quarks in about 10, due to weak force.

A number of theorists believe the particle is a kind of charmonium - the term for a pair of charm quarks orbiting each other.

The discovery of charm quarks - and J/ψ mesons - led to a rapid series of scientific breakthroughs.

As speedy as pions, muons, and charmed quarks, they were all places at once, the possessors of pure and boundless energy.

The first generation includes up and down quarks, the second strange and charm quarks, and the third bottom and top quarks.

In particle physics, a hyperon is any baryon containing one or more strange quarks, but no charm quarks or bottom quarks.

Their world abounds in gluons that stitch particles together, charmed quarks and antiquarks with more colors than Joseph's coat and imaginary axions, photinos and gravitons.

Baryons with strange and charm quarks have been spotted in various particle accelerators over the years, but those containing a heavy, bottom quark have been harder to come by.

What makes them different from other baryons (particles made of three quarks) is that they must have at least one strange quark, but no charm quarks or bottom quarks.

He said he's been around long enough to remember when the discovery of charm quarks set off 18 months of confusion, and called them "the most exciting months of my physics lifetime."

Since they are fermions (particles that can not have more than one of that particle at the same place at the same time), charm quarks have a spin of 1/2.

Since it decays into J/ψ and φ mesons, it has been suggested that this particle is composed of charm quarks and charm antiquarks, possibly even a four quark combination.

They include detection of many more particles that contain strange quarks than an ordinary smash-up would produce, and fewer particles containing charm quarks - the indications seen by the Geneva lab's detectors.

Physicists at Brookhaven National Laboratory and SLAC National Accelerator Laboratory had in 1974 discovered particles made up of charm quarks and their antimatter partners, anticharm quarks.

The title references quarks which are sub-atomic particles; "Strangeness" and "Charm" are playful terms used by physicists to refer to how many Strange and Charm quarks are within a particle.

From the intricately arcing debris, which resembles the explosions of a fireworks display, physicists have managed to deduce the existence of such invisible, ephemeral beasts as charm quarks, tau leptons, colored gluons and Z bosons.

Studies of rare decays and searches for exotic particles and precision measurements of phenomena associated with mesons containing bottoms and charm quarks, as well as phenomena associated with tau leptons are possible.

The resulting electroweak theory and Standard Model have correctly predicted (among other discoveries) weak neutral currents, three bosons, the top and charm quarks, and with great precision, the mass and other properties of some of these.
