Sentences with phrase «charm quarks»
Charm quarks are tiny particles that make up matter. They are part of a group called quarks, which are the building blocks of protons and neutrons. The term "charm" refers to one of their properties, which is related to their behavior and interactions with other particles. Full definition
LUCKY CHARM Scientists with the LHCb experiment near Geneva have found a new particle (illustrated) that has two heavy quarks, known as charm quarks, and one up quark.

Baryons can be composed of a variety of quark combinations, two up quarks and one charm quark, for example, or one «strange» quark and two «down» quarks.
Mass and energy are equivalent at these small scales, so Giorgi and his colleagues reason that they can get the mass of Ds (2317) to fall within the right range by tinkering with the strength of the strong nuclear force that binds the charm quarks and the strange antiquarks.
In 2002, scientists with the SELEX experiment, located at Fermilab in Batavia, Ill., reported that they had discovered a particle composed of two charm quarks and a down quark (SN: 7/6/02, p. 14).
Because the charm quarks are a particularly heavy variety of quark, scientists should be able to use the new particle to perform different types of tests of their theories of particle interactions.

Theories predicted the new particle — dubbed Ξc + c + (pronounced ka - sigh - see - see - plus - plus)-- more than 30 years ago, but charm quarks are rare and about five times heavier than up quarks, making them unlikely particle ingredients.
The new particle is ideal for this purpose because it is the first known that both contains a charm quark and has spin 3.»
The scientists have often created baryons containing two and even three strange quarks, but no one had ever detected a baryon containing more than one charm quark, at least no one thought so.
