i'm not certain this belongs here but any way. with all this "talk" or higgs Bosons ithought it would be intresting to start adiscusion about strange and hypothetical particals.

One of which i have bumped into is a hypothetical partical called a tachyon, it can travel faster then light i have't reseached it that much but when i find out more i'll let you know.

until then add your own funny particles theories.

Cheers

It is doubtful that the tachyon - a putative particle with a slowest possible speed of c - exists, since it would violate both causality and special relativity.

http://math.ucr.edu/home/baez/physics/Part...r/tachyons.html

Another hypothetical superluminal particle similar to the tachyon, but having greater energy, is the superbradyon.

Why is it that the speed of light is the limit why is'nt it c + 67 or c / 23 for example?

who comes up with these names!? baryons, tachyons, strange quarks, superbradyons, anti-tau-neutrinos!

Hi ChromeStar,
Here's my answer for what it's worth.

Read The following 2 or 3 posts to get the full story.

Hi gavwvin,
They are old Greek names. Lepton means "light", tachyon means "swift"...

This might be helpful:
Tachyon

And here's my reply:

Hyperon: any baryon that is not a nucleon; unstable particle with mass greater than a neutron

Tardyon: all particles which always move with a velocity below the velocity of light. These are protons, electrons, muons, atoms - the common matter we already know.

Luxon: all particles which always move with the velocity of light in empty space. These are every type of electromagnetic radiation, gluons and maybe neutrions and gravitons.

Tachyon: any particle moving faster than light

Bradyon: another word for tardyon

Fermion: include leptons (Electrons, muons), baryons ( neutrons, protons, lambda particles), and nuclei of odd mass number such as helium-3; subatomic particles that have odd, half-integral angular momentum (1/2, 3/2, etc.), and obey Fermi-Dirac statistics and the Pauli exclusion principle.

Boson: subatomic particles that possess integer spin (i.e., angular momentum in integer units.) and are governed by Bose-Einstein statistics; mediate interactions between fermions, include photons, mesons (Pions and kaons), and nuclei of even mass number ( helium-4, etc.); differ from fermions in that any number of bosons can occupy the same quantum state Atoms only exist in certain "quantum states" which are defined by a set of integer-like properties.

Baryon: heavy subatomic particles made up of three quarks; protons and neutrons, as well as other particles, are baryons. The other class of hadronic particle is built from a quark and an antiquark and is called a meson; the three quarks that make up a baryon can only produce half-integer values, while meson spins always add up to integer values.

Nucleon: protons and neutrons

Hadron: atomic particles associated with the strong nuclear force. Hadrons include mesons (Pions and kaons) and baryons (Protons, neutrons, and sigma particles

Meson: have integer spins; mediate the interaction between fermions in nuclei; composed of an even number of quarks and anti-quarks.


Lepton: fermions that do not take part in strong interactions; have a half-integral spin and obey the Pauli exclusion principle; appear to be fundamental particles as they cannot be broken down into finer units of matter.

I'd like to add a couple pieces of data to your list. The term 'meson' also refers to muons and tauons which are the heavy leptons, and have half-integer spin.

You might also point out that Lepton refers to electrons, muons, tauons, the three varieties of neutrinos, and the antiparticles for each.

It is worth noting that some of these terms are much older and come from a time when we knew less about the nature of all these particles.

How about an infinate Higg's or Panhiggs.

The Higgs B? Just the boson for mass...hypothetical.

I personally do not believe that it exists.

I said an infinate particle for mass. Since the Big Bang it has been disturbed and has produced some amazing things in its struggle to regain control. The question is can the Universe ever return to its infinate calm from before the "Bang"?

Hi all

where can one find a translation book or greek/english dictionary.

it would be intresting to find name meanings.

any one know?

P.s. Thanx Ferg, i think it will help but i'll need time to contemplate.

That is a good site. I hadn't seen it before.
As to your question about Greek-English translation, there are a number of on-line sites that can do this. The trick is to be able to transliterate to the right characters. Some are obvious and some [especially most vowels] aren't.

I've seen that site before - very basic stuff.
