someone asked me about the pentaquark and what does it mean. Fisrt of all, coming back to the neutrinos, sorry that i cannot
provide you with links, since with a simple search you can find lot's of documents and i am not sure which one is good for someone with no science or
mathematical background. Try to avoid the most complicated explanations and the most mathematical, i am too avoiding these things as well!!!
Now the neutrino indeed has a mass, it is a tiny particle, but it has a mass!!
As i told you a few electronvolts per squared speed of light. And it is travelling with the speed of light. In neuclear reactions the neutrino has
been theoretically predicted and practically 'seen'. Since 1987 there have been many experiments and research in the field and they indeed have
detected a lot of them. Our sun is a source of these tiny particles as well as all stars, especially the higher mass stars, like supernovae.
Now for those asking about the quarks, the quarks appear to be on a formation of two to three. For example a proton has 2up quarks and one down. The
neutrons have 2down and one up. Therefore you can explain why the neutron does not attrack the electron, but the proton does!!!!
For example the up quark has a charge of +2/3(using numbers), so the proton = 2up + 1down has a total charge of +2/3+2/3-1/3 = 1.
The down quark has a charge of -1/3. Now the neutron has a total charge of 2down + 1up = -1/3-1/3+2/3=0.
The pentaquark it may be 2up one down one strange and one charm let's say. Where strange and charm the other 'flavours' as we called them. This
will give a total charge of +2/3+2/3-1/3+2/3-1/3=4/3?? More than one??
I am not quite sure, not for the maths, but the charge of such particle.
Don't forget that quaks may not be the simplest form of matter, that 'may' with great precision, since each one is a different manifestation of a
That's all for now, try to find something about the Higgs Boson, the particle said to give 'life' to everything else, i don't remember its mass.
Can someone have a look on that?? This is a great challenge!!! Also the top quark is a mystery since it hasn't been discovered so far, unless a new
theory has alredy created that i am not aware of.
See you guys.
