An analysis of anti matter

Antimatter

If a particle has other attributes such as an electric charge Qthen the anti-particle has the opposite attributes or An analysis of anti matter charge of -Q. If the matter body in Figure 1 d is replaced by a same mass antimatter body. Previously, scientists were stumped by the fact that it seemed to predict that particles could have energies lower than when they were at "rest" ie pretty much doing nothing.

This means that the laws of physics for antiparticles are almost identical to those for particles; any difference is a tiny effect. It is one of the biggest mysteries in physics to date.

People have asked "what is matter? On Paul Dirac, who predicted the existence of antiparticles Image: So it can be concluded that the antimatter gravity must be positive, this means that the gravitational force between matter and antimatter is attractive and is same as that between matter and matter.

When a particle and its antiparticle meet, they annihilate each other — disappearing in a burst of light. Indeed, atoms are made of electrons that whiz around the fixed protons and neutrons in their nuclei, which are made of quarks.

InCarl Anderson discovered the positron while measuring cosmic rays in a Wilson chamber experiment.

Recent data released by CERN states that, when fully operational, their facilities are capable of producing ten million antiprotons per minute. The total energy of electron is as follow, 12 The total energy of positron is as follow, 13 So for energy conservation before and after ray photon transfer into electron and positronfollow equation is gained 14 Consider Equation 711 and 14the potential energy of ray photon before and after transfers into electron and positron is gained as follow, 15 So it can be simplified to 16 If the antimatter gravity is repulsive from matter, the Equation 15 becomes 17 So it can be simplified to 18 Above equation is paradox, it conflicts with that photon has potential energy in gravitational field, if the antimatter have no interaction with gravity field, Equation 15 becomes 19 The Equation 19 is paradox too, it also conflicts with that photon has potential energy in gravitational field and should be singularity at one place.

Dirac, however, accepted that the equations were telling him that particles are really filling a whole "sea" of these lower energies — a sea that had so far been invisible to physicists as they were only looking "above the surface".

This distinction is the subject of study in a number of experiments around the world that focus on differences in the decays of particles called B-mesons and their antiparticle partners.

The gravity potential is zero at the middle of two matter bodies and infinite distance. The neutron--although electrically neutral--has a magnetic moment opposite that of the anti-neutron. Some hundreds of millions of antihydrogen atoms have been made in this fashion.

Antimatter

Dirac interpreted the equation to mean that for every particle there exists a corresponding antiparticle, exactly matching the particle but with opposite charge.

It is believed that every particle we know of has an antimatter companion that is virtually identical to itself, but with the opposite charge. In order to answer this question, we need to better understand that tiny part of the laws of physics that differ for matter and antimatter; without such a difference, there would be no way for an imbalance to occur.

It is similar with Figure 1 a. InPaul Dirac postulated the existence of positively charged electrons. Specifically, physicists discovered a 1 percent difference between pairs of muons and antimuons that arise from the decay of particles known as B mesons.

A cloud chamber picture taken by Carl D. For example, when a proton and anti-proton annihilate at high energies, a top-anti-top quark pair can be created!

This explanation for the asymmetry gained credence inwhen CP violation was seen in the decay of B-mesonsparticles that are heavier than K-mesons and thus able to account for more of the asymmetry.

So why is there far more matter than antimatter in the universe? The most stringent tests of CPT to date are measurements of the ratio of the magnetic moments of the electron and positron to two parts in a trillion R.

Each antiatom survived for only about billionths of a second before it came into contact with ordinary matter and was annihilated. Although positrons are readily created in the collisions of cosmic rays, there is no evidence for the existence of large amounts of antimatter in the universe.

Measurements made by the DZero collaboration, a member international group, are still limited by the number of collisions recorded so far.

Assume there are matter and antimatter bodies with same mass.

What is antimatter?

The Figure 1 b shows the potential gravity field produced by antimatter body. The electrons in this plasma cool via cyclotron radiation, and then sympathetically cool the antiprotons via Coulomb collisions. At Penn State University, the Antimatter Space Propulsion group is addressing the challenge of using antimatter annihilation as source of energy for propulsion.

A strongly proof is that photons are their own antiparticles, and in all respects behave exactly symmetrically with respect to matter and antimatter particles.

Eventually, it can be concluded that the sign of antimatter gravity is positive. Thus, there are positive and negative muonspositive and negative pi- mesonsand the K-meson and the anti-K-meson, plus a long list of baryons and antibaryons.But when matter and antimatter come into contact, they annihilate – disappearing in a flash of energy.

The Big Bang should have created equal amounts of matter and antimatter. So why is there far more matter than antimatter in the universe?

At CERN, physicists make antimatter to study in experiments. Antimatter particles can be defined by their negative baryon number or lepton number, while "normal" (non-antimatter) matter particles have a positive baryon or lepton number.

[6] [7] These two classes of particles are the antiparticle partners of one another. Aug 22,  · For the electron there should be an "antielectron", for example, identical in every way but with a positive electric charge. The insight opened the possibility of entire galaxies and universes made of antimatter.

But when matter and antimatter come into contact, they annihilate – disappearing in a flash of energy. 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.

Project: Matter vs Antimatter - Course: HETNovember Supervisor: Dr. Jennifer Coopersmith - Student: Eduardo Manuel Alvarez 1 – Introduction Nobel prize in physics was earned by the Englishman Paul Dirac, based on his spectacular achievements in the development of quantum mechanics.

Antimatter is a material composed of so-called antiparticles. It is believed that every particle we know of has an antimatter companion that is virtually identical to itself, but with the opposite charge. For example, an electron has a negative charge.
