when matter and antimatter were created in equal amounts in the Big bang? Somehow this balance changed over time to a dominance of matter.
and antimatter lies with neutrinos which is why observing CP violation in neutrinos would be exciting Manly adds.#
#One in a trillionthe T2k experiment based in Tokai Japan expects to collect 10 times more data in the near future including data with an antineutrino beam.
and how other particles known as mesons are made from pairs of quarks and their antimatter counterparts, antiquarks.

#Tabletop accelerator shoots cheap antimatter bullets Make way for the antimatter gun. A tabletop device just 10 square metres in size can spit out energetic bursts of positrons as dense as those kicked out by the giant particle-factories at CERN.
Each positron-packed bullet lasts for just a fraction of a second so don't expect to fill the tank of your antimatter engine any time soon.
Antiparticles have the same mass as their ordinary particle counterparts but carry an opposite charge and spin.
Huge machines at particle physics labs such as CERN near Geneva Switzerland have been churning out antimatter for over a decade.
The team call their device an antimatter gun because the bursts of positrons last just 30 femtoseconds (quadrillionths of a second).
In 2008 scientists at the Lawrence Livermore National Laboratory in California produced large quantities of antimatter by directing an extremely powerful laser at a tiny gold disc.
This is similar to the powerful streams of matter-antimatter observed outside pulsars and black holes. CERN physicist Niels Madsen notes though that the tabletop device has limitations.
whereas to make an anti-atom you also need antiprotons which are almost 2000 times more massive.
For now he says making heavier antiparticles is not doable in a small lab in a cheap fashion.
Nor does the smaller machine address the problem of antimatter storage. To hold antimatter stable it must be chilled
and the tabletop method makes searing-hot beams of particles moving at near light speed. As an alternative says Sarri the beams can be used to mimic the way particle fountains from black holes

#Wrong Turn in the Skies Leads to Accidental Antimatter Discovery Antimatter plentiful in science fiction is a rare phenomenon in the real world
he was surprised to discover antimatter in their midst. Dr. Joseph Dwyer and the crew spent long minutes trying to find their way out,
and discover that he found antimatter in the thunderclouds. When antimatter comes into contact with a particle of normal matter
the two wipe out each other, and it doesn stick around long enough for scientists to study it at length.
Until now, scientists have theorized only that antimatter could exist in a thunderstorm actually discovering it was nothing short of a major shock. his was so strange that we sat on this observation for several years,
Dwyer is now chasing down antimatter by releasing weather balloons and planning more head-on flights into storms h
By making precise measurements of particle mass and electric charge, researchers from the University of São paulo (USP) and the University of Campinas (UNICAMP) confirmed the symmetry between the nuclei of particles and antiparticles in terms of charge, parity
and then compare that to how antiparticles join in the antinuclei. The researchers are also hoping ALICE will help them better understand how heavy quarks such as the charm
"After the Big bang, for every particle of matter an antiparticle was created. In particle physics, a very important question is
and combined it with recent high-resolution measurements comparing proton and antiproton properties. As we know
they produce a massive amount of particles and antiparticles. Data shows these particles combine to form nuclei as well as antinuclei at almost the same rate,
they will better grasp the relationship between matter and antimatter.""These laws describe the nature of all matter interactions,
unlike all known subatomic particles, serve as their own antiparticles. These theorized particles ave yet to be explored.
which are called subatomic particles mesons that are composed of one quark and one antiquark each. For a while, f0 (1500) was considered the more promising candidate of the two,
why there is more matter than antimatter in the Universe. Notes 1 The Ds3*(2860) particle is a meson that contains a charm antiquark and a strange quark.
The subscript 3 denotes that it has spin 3 while the number 2860 in parentheses is the mass of the particle in the units of Mev/c2 that are favoured by particle physicists.
