Action at a distance is the simplest non-local interaction. But then in relativistic local field theories signals cannot travel at velocities more than the speed of light. This is taken into...

It is known that QCD is based on SU(3) Yang-Mills theory. This reminds me to a lecture around 2009 , the lecture was given by Prof. Yu P. Rybakov, and it was about Yang-Mills theory. Actually i...

CPT is a symmetry of fundamental interactions. Therefore CPT conservation is built into relativistic quantum field theories, such as electroweak theory. However we know that CP is violated in weak...

We do not know whether the neutrino is a Dirac particle or a Majorana particle. If neutrino turns out to be a Majorana particle then two additional phases are to be introduced in the 3x3 lepton...

ABSTRACT Since the discovery of the positive electron (positron) in 1932, physics has ignored the more plausible possibility that charge is not a fixed property of subatomic particles. Instead of...
