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.
A blip of electric current at the end of an atom-thick wire has brought physicists one step closer to confirming the existence of Majorana particles, entities that are their own
antiparticles.
In general, for any particle A and its
antiparticle [bar.
In other cases, one plus one equals one: Whitehead mentions the drops of water; candle flames also qualify and the so-called annihilation of matter (that refers to transformation of one particle and one
antiparticle into one photon) would do as well.
The hunt for a long-sought particle that does not have a distinct
antiparticle twin might be over.
I don't doubt I'd be pants at puffing hard in hot places, and though I do know some cracking science words, like positron (that's your basic electron
antiparticle, of course), my knowledge of physics is full of black holes.
The hole left behind in the negative energy spectrum is the
antiparticle (positron in this case) that also occupies a positive energy state.
It presumably has a neutrino of its own, and there is surely an
antiparticle for each, so that twelve leptons are now known.
Furthermore, for each particle there is a mirror image with identical mass and opposite charge(s): its
antiparticle.
More specifically, when a gamma-ray photon enters into contact with a diffuse photon it may 'disappear', giving rise to an electron and its
antiparticle, a positron, which reduces the intensity of the beam.
First proposed more than 70 years ago, a Majorana fermion is a theoretical type of particle that is its own
antiparticle.
