Without going into details of a sound engineering, we have here only scratched the surface of a basic theory describing the ability of a system composed of antiparticles to interact with a specific refracting and dispersive material in order to exhibit a dynamical negative mass.
Specifically, the UCLA researchers write, the asymmetry may have been produced as a result of the motion of the Higgs field, which is associated with the Higgs boson, and which could have made the masses of particles and antiparticles in the universe temporarily unequal, allowing for a small excess of matter particles over antiparticles.
Then there are "secondary colors," or the stranger sub-atomic particles that started to appear in scientists' heads and as unexpected by-products of experiments around WWII: pions, muons, antiparticles, quarks, positrons and other strange particles.
Antiprotons, the relatively exotic antiparticles of the proton, are difficult to create and were not to be squandered.
Subatomic particles are usually emitted as an atom decays and loses protons, neutrons, electrons, or their antiparticles.
At the subatomic level, for example, particles should behave like their alter egos, called antiparticles.
According to superstring theory, to describe the motion of a string we need eleven dimensions, plus antiparticles and a mirror image of particles, called superparticles.
Like Eagleton's abyss of the other in the self, the quantum world presents us with "a fuzzy, amorphous, probabilistic mixture of all possibilities" (Greene 112), a dizzying and dazzling sub-atomic world of interchangeable forces, migrations, exchanges, particles, fields, antiparticles, and trajectories.
After mixing cold clouds of trapped positrons and antiprotons - the antiparticles of the familiar electron and proton - under closely-monitored conditions, researchers identified antihydrogen atoms, formed when positrons bind together with antiprotons.
Life is universal like elementary particles--protons, neutrons, and electrons or in some places antiparticles of the matter.
A Japanese-led team of international researchers said Monday it has discovered more evidence suggesting that particles and antiparticles may not be completely symmetrical, which could explain why antiparticles vanished at an early stage in the history of the universe.
The trouble is that K-mesons are unstable, and die within less than a millionth of a second, leaving a trail of other particles or antiparticles.
Thus, for instance, positrons and antiprotons are the antiparticles of electrons and protons, respectively.
After most of these particles and antiparticles killed each other off, there was just enough matter left to make a universe.
C means changing particles for antiparticles, P means taking the mirror image, so left and right are interchanged.
