Quarks

The name quark was first used in physics by physicist Murray Gell-Mann, from a line in James Joyce's "Finnegans Wake": 'Three quarks for Muster Mark'. Although Joyce appears to have meant it to be pronounced as it is spelt, physicists pronounce it to rhyme with fork.

Pronunciation: quork


Quark "menu"

Like ice cream, quarks come in different "flavors".
There are six basic quark flavors and six more "anti-flavors".

Quarks are believed to be one of the basic building blocks of matter
They combine to form "hadrons", particles of matter and anti-matter.

Flavor Particle Anti-particle
Up u u-bar
Down d d-bar
Strange s s-bar
Charm c c-bar
Top t t-bar
Bottom b b-bar

For your "hadron", choose a combination of two, three, four, or five of the above.
(No "single scoops" are allowed.)

A typical nucleon includes three quarks.

NEUTRON = 2d + u

PROTON = 2u + d

Mesons are particles that have one quark and one anti-quark. There are many types. One type is:

B MESON = b-bar + (u or d) [regular matter]

B-BAR MESON = b + (u-bar or d-bar) [anti-matter]
