Mesons are built from a quark plus an antiquark, while baryons are composed of three quarks. The proton is a combination of two up quarks plus a down quark (written The Discovery of the Top Quark [From the Archive] Finding the sixth quark involved the world's most energetic collisions and a cast of thousands By Tony M. Liss , Paul L. Tipton on September 29, 2011 Discovery of the top quark. On March 2, 1995, physicists at Fermilab's CDF and DZero experiments announced the discovery of the top quark, the last undiscovered quark of the six predicted to exist by current scientific theory.
The Quark Discovery. Fifty years have passed since the publication of two articles in Physical Review Letters on October 20, 1969 [ 1 , 2 ]. These articles marked the discovery of the quark and led to the 1990 Nobel Prize in Physics for Jerome Friedman, Henry Kendall and Richard Taylor. The symposium features presentations by theorists and

In the period following World War II, there was a rapid development of particle physics. With the construction of synchrotrons and the development of detector technology, many new particles were discovered and the systematics of their interactions investigated. In 1964, Gell-Mann and Zweig proposed B = 1/3 quarks to explain hadron spectroscopy, using an isodoublet.

The strange quark or s quark is the third lightest of all quarks, a type of elementary particle. Strange quarks are found in subatomic particles called hadrons. Examples of hadrons containing strange quarks include kaons, strange D mesons, Sigma baryons, and other strange particles. According to the IUPAP the symbol s is the official name, while "strange" is to be considered only as a mnemonic. The name sideways has also been used because the s quark has an I3 value of 0 while the u and d quarks

All Quark Expeditions include a parka designed to protect you during your expedition. These will be distributed to you onboard the vessel for ship programs or once you arrive at your camp (for land expeditions). The Quark Expeditions Parka is yours to keep!

All combinations of 3 quarks and 3 antiquarks. give the observed 9 pseudoscalar. mesons. It is no accident that the quark—the building block of protons and neutrons and, by extension, of you and everything around you—has such a strange and charming name. The physicist who discovered it, Murray Gell-Mann, loves words as much as he loves physics.
