By the 1950s, when Yang–Mills theory, also known as non-abelian gaugetheory, was discovered, it was already known that Quantum Electrodynamics (QED) gives an extremely accurate account of...

Electron/positron are stable particles, provided they have no "rendezvous". Muon and tauon are unstable. In analogy the electron-"neutrino" should be stable and the muon- and tauon-"neutrino"...

Mass is a property of matter, how can we distinguish intrinsic from physical? I understand that mass is a scalar and physically measurable quantity. In case of space, it is a vector or a tensor ....

Standard texts say that whenever the rate of annihilation goes below the rate of expansion "decoupling" takes place and when the abundance of the decoupled entity does not change with time we say...

Non-locality is a curious feature, yet essentially a quantum attribute that is linked to the violation of Bell inequality of any form. It arises from the impossibility of simultaneous joint...

In the study of the electron the term h.c^4, or more specifically the exact term 8pi.h.c^4.alpha seems to have a special significance. The question is what (dimensionally or otherwise) do either...

Usually photons are considered to be uncharged and to have spin 1 hbar. But could a variety of photon have spin 1/2 hbar if it is electrically charged and forms an electron? What if such a charged...
