Questions related to Elementary Particle Physics
The latest discovery of the BICEP2 shed new light on negative gravity. Nevertheless it's still a theoretical assumption and there are no experiments that prove it. What is the probability that two...

It is known that Higgs mechanism is right but the theory does not fully explain mass and gravitation (see for instance http://www.higgs-boson.org/). In the meantime, there is a rather old paper...

I learnt that before half life only one half disintegrates and others don't, why does this happen? I mean every nucleus is unstable then why does the disintegration happen at a time with all...

Both Dirac and Majorana equations are identical by form. But imposing electric neutrality condition on Majorana spinors results in absolutely different physics. Why is that? Is it charge...

From WMAP result (arXiv:1212.5225) we know Baryon/photon ratio η has the value (6.19 ± 0.14) × 10^(-10). Now alternatively this can also be defined as Y_{B}=(n_{baryon}-n_{antibaryon})/s,...
