Hi Differences between particles and antiparticles are not only the electrical charge but all kind of "charges". Basically, if a proton got a baryonic charge of +1, the antiproton will get a baryonic charge B of -1. For instance, in beta decay, there is conservation of the letponic charge...

It should be Gell-Man amd his friends ...

Hi :biggrin: I'm agree with you, dextercioby, when you sau that the discovery of QGP will confirm the power of the standart model, but I don't believe it's like a normal plasma. In QGP, quarks are free, and calculations with lattice QCD show us that there where a phase transition (sign...

You must know the 3 states of matter: liquid,solid,gaz, but at height temerature, you can also find a state called plasma(electrons are free) The fifth state of matter you're talking about might be the QGP (Quarks and GLuon PLasma). Scientists believe that QGP is a state where quarks are...

quark exchange ? Hi If you're talking about n->p+e+neutrino process, I don't understand the exchange of quarks. In this case, there is "just" a change of nature of the quark (d->u+e+neutrino) but no exchange. I assume this is not the answer you were wondering, so try to develop your...

I hope this will help you Hi Your electron is interacting with electrons of your atom of tungstem through the electromagnetic force. He is changing is momentum and losing kinematic energy during this interaction. This energy loss goes to electrons of the tungsten and makes them change of...

A candle in the dark Hi It is quite simple: - You have access to a number of charges (electrons) collected by the anode in your TPC when a ionizing particule came in - you may know the energy needed to create a electron/ion pair in your gaz (in eV) - so you can infer the energy lost...

They do not gain mass ... It is the interaction of the gluons (with themselves by strong interaction cos' they get color, with the quarks ..) that give the major part of the mass of the nucleon (think of the famous E = m * c * c, that bond mass to energy);

It does , thanks. I just thought that there were a "classical" explanation, like photons hiting electrons and going back to my eyes or photons passing trough matter without doing any interacion. Assuming that, I was thinking that R was equal to...

I'm agree with you because of the daily experience, but even if optics can explain how ligth reflect on a mirror, I wonder how can modern physics (QED ...) descibe the reflection ...

Could you explain me how does Light reflect on a mirror? I assume that Compton effect on electrons is the only way for light to come back to my eyes but in that case, there would be a change of frequency of the photon (and a change of color). Does it mean that it is not me in the mirror ...
