Could you give me a definition for each of these particles?

Question

I know about Electrons, Protons, and Neutrons.

But what are these other particles?
Positrons, Photons, Neutrinos, Mesons, and Hyperons?

Answer 1

positron-electron with a positive charge instead of negative
photon-packet of em energy
neutrino-like an electron, but electrically neutral
meson-composite particle composed of a quark and anit-quark
hyperon-another type of subatomic particle, a type of baryon

Answer 2

Positron is an electron with a positive charge, i.e. anti-matter electron.

Photon is the eletromagnetic force mediator, it carries energy in the form of radiation (from radio waves, to micro waves, to infra-red, to visible light, to ultraviolet, to x-rays, all the way to gamma radiation)

Neutrinos and very light (once thought to be massless, but they may have some) and neutral particles that basically carry away a spin (without neutrinos, some nuclear reactions would be left with some unaccounted for spin, so it was theorized that a particule would be carrying the spin with no charge and no mass. Later experiments showed the elusive particle to actually exist)


Mesons are particles that are made of 2 quarks (protons and neutrons are made of 3)

Hyperons are baryons with non-zero strangeness (strange is a type of quark) which can decay into a proton or neutron and mesons.


The particle phusics is a real zoo. And it gets more complicated all the time. Just keeping up with the definitions is almost a full time job, so imagine those that have to come up with the theories...

Answer 3

Its the lingo of particle physics, the study of the most fundamental constituents and interactions of the physical world.They are fundamental point like building blocks of everything. As particle accelerators churned out new particles, many were easy to understand and categorize, but some appeared especially strange, with a curious mix of strong and weak properties that seemed at first to be mutually contradictory.New words were coined for new particles and concepts including mesons and baryons, hadrons and leptons, bosons and fermions, flavor and families.The words are alien and unfamiliar but they help organize our thinking about the world.In the 1950's some unusual tracks began to appear in bubble chamber images.The particles that left these tracks were called "strange particles", because scientists could make no sense of some aspects of the tracks. Strongly interacting particles are called "hadrons", including protons , neutrins, pions, and strange particles. Weakly interacting particles are called leptons, including electrons, muons, and neutrinos.Hadrons are further divided into "baryons" or "mesons".baryons have half integer spin.Msons were proposed by Yukawa as "force carriers".All mesons have integer amounts of spin.Each of these particles can have various other quantum numbers.For example, some mesons may have strangeness 0, some may have strangeness +1, and so on.hope this helped somewhat explain the strange happenings and goings on in the realm of the "particle zoo".Good day!

Answer 4

The positron is the anti-matter equivalent of an electron. Photons are the particle representation of electrmagnetic forces, and are the quanta of electromagnetic waves. the nutrino is a very light particle with no charge (http://en.wikipedia.org/wiki/Neutrino). Meson are a class of sub-atomic particles associated with the force that binds the atomic nucleus (http://en.wikipedia.org/wiki/Mesons) Hyperons are heavy sub-atomic particles (http://en.wikipedia.org/wiki/Hyperons)

Answer 5

Go to wikipedia.com. they know everything.
