All quarks have a baryon number (B = 1/3) and a lepton number (L = 0).

The other four quarks are known as the Charm & Strange quarks, and Top & Bottom quarks which are also successively heavier but also both highly unstable. Don't worry about them. Now the key point: Several quarks can be combined using gluons. Any combination of a multiple of quarks is known as a hadron.

In the last weeks of 1999, folks weren’t just prepping the champagne and confetti for New Year’s Eve. Some people were stocking up on canned food and toilet paper, preparing for disaster to strike at the dawn of the new millennium.

Oct 18, 2023 · Quark “ colours” The interpretation of quarks as actual physical entities initially posed two major problems. First, quarks had to have half-integer spin (intrinsic angular momentum) values for the model to work, but at the same time they seemed to violate the Pauli exclusion principle, which governs the behaviour of all particles (called fermions) having odd half-integer spin. A supermultiplet of baryons that contain the up, down, strange and charm quarks with half-spin. Charm quarks can exist in either "open charm particles", which contain one or several charm quarks, or as charmonium states, which are bound states of a charm quark and a charm antiquark.
