antiquark

[′an·tē¦kwärk]

(particle physics)

The hypothetical antiparticle of a quark, having electric charge, baryon number, and strangeness opposite in sign to that of the corresponding quark.

For one thing, it could end what had been a puzzling absence of evidence for particles with groupings containing more than three quarks or antiquarks, which theorists for decades have been expecting to show up in accelerators.

New quarktet: subatomic oddity hints at pentaparticle family

According to this consideration, the type-I quark-antiquark annihilation cancels only the color imaginary energies of a quark and a different flavor antiquark, while the type-II quark-antiquark annihilation cancels both the electric and color imaginary energies of a quark and a same flavor antiquark.

Predictions of high energy experimental results

The only difference between a quark and its corresponding antiquark is that their imaginary energies (thus their electric and color charges) have opposite signs.

Fundamental elements and interactions of nature: a classical unification theory

From the analysis, there are a set of allowed states J (PC) for a quark and an antiquark in net spin 0 and 1 coupled to orbital angular momentum, L, and total spin J = L + S.

Let's note by q = quark [member of] {Up, Down, Top, Bottom, Strange, Charm}, and by a = antiquark E {Up, Down, Top, Bottom, Strange, Charm}.

On emergent physics, "unparticles" and exotic "unmatter" states

So, physicists must turn to theory to distinguish those features due exclusively to the decay of the b quark from the elaborate dance of quarks, antiquarks, and gluons inside a decaying B meson.

Starting from square one: the intricate behaviors of quarks may finally yield to calculation

Each particle also has an antiparticle, such as an antiquark.

E (14 trillion electron-volts) = m (?) [c (close to the speed light).sup.2]: this fall, the massive Large Hadron Collider beneath France and Switzerland will switch on. Protons moving at almost the speed of light will collide with energies high enough, physicists hope, to solve matter's biggest mysteries

In meson for example (a simpler case) the quark and the antiquark must undergo rapid interchange of identity into each other (through exchange of force particles) to remain in a stable form.

Majorana particles: a dialectical necessity and not a quantum oddity

In one method, a quark pairs with one of its opposites, an antiquark, to create a type of matter called a meson.

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 ([14]), such as those shown in Fig.
