If a paired quark and antiquark
come into contact, they annihilate each other and the flux tube linking them disappears as well.
Previous work found differences between matter and antimatter for mesons, which consist of one quark and one antiquark
In reality, the strong force is so strong that all color-charged gluons and quarks are bound tightly together into color neutral hadrons, either the mesons which consist of a quark and antiquark
with corresponding color and anticolor, or the baryons, which consist of three quarks of the three colors, which cancel to color-neutrality.
ascertain to date whether a quark or an antiquark
is smaller than a
In one method, a quark pairs with one of its opposites, an antiquark
, to create a type of matter called a meson.

gaging intrauterine rhoduline astigmatism.
There were but a few of these quarks, each accompanied by an antiquark
, and by grouping them in different combinations, either two or three at a time, the various hadrons could be accounted for.
While mesons are made up of a quark and an antiquark
, baryons (such as protons and neutrons) are composed of three quarks, of which at least two are light.
, of Brinscombe, said 63 jobs will go at its Wimberley Mills factory, leaving 83 workers to produce the resin models loved by collectors.
The basic idea is that a meson is a quark and antiquark
bound together, and our understanding is that the glue holds those together.
For example, a baryon is predominantly formed from three quarks, and a meson is mainly composed of a quark and an antiquark
in the models of Sakata, or Gell-Mann and Ne'eman on hadrons (), such as those shown in Fig.
LHCb examines the decay of B mesons, particles composed of a specific pairing of a quark and antiquark
--the bottom antiquark
and either an up or a down quark.
