The antimatter particles corresponding to electrons, protons, and neutrons are called positrons (e+), antiprotons (p), and antineutrons (n. Now researchers are looking into the actual transition process of the charm meson itself, according to the press release. antimatter, substance composed of subatomic particles that have the mass, electric charge, and magnetic moment of the electrons, protons, and neutrons of ordinary matter but for which the electric charge and magnetic moment are opposite in sign. 'By comparing the charm meson particles that decay after travelling a short distance with those that travel a little further, we have been able to measure the key quantity that controls the speed of the charm meson oscillation into anti-charm meson – the difference in mass between the heavier and lighter versions of charm meson,' he continued. The virtual absence of antimatter and preponderance of matter in the Universe today remains one of the biggest conundrums facing physics. The matter and antimatter pairs have the same mass but opposite electrical charges. For example, proton and antiproton are a pair of matter and antimatter, respectively. Therefore, antimatter is the opposite of matter. 'Charm meson particles are produced in proton–proton collisions and they travel on average only a few millimeters before transforming, or decaying, into other particles,' Tim Gershon, professor in the Department of Physics at the University of Warwick, said in a press release from the University of Oxford. Antimatter is the matter containing antiparticles that contribute to the formation of matter. They were able to measure this via proton collisions using the Large Hadron Collider. In fact, the scientists found that the matter and antimatter in the charm meson had a difference of just 0.00000000000000000000000000000000000001 grams. An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at 6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current technology.
