What is the precise lepton no violating scale while working in Inverse Seesaw regime?

Text says that, the essence of the seesaw mechanism demands the lepton number violation at a high energy scale. As a result left handed neutrinos get tiny masses through the formula m_{\nu} =...

Where do physical laws and constants reside in nature and how do they find expression in actions?

Much has been learned about what laws exist and what possibilities occur in actions. Very little is known about where the laws reside or which mechanisms describe how they govern physical...

Can electroweak force transfer heat?

We know that the electromagnetic force can transfer heat and make the temperatures go up and down. Entire thermodynamics is based on this heat transfer. My question is whether the electroweak...

Can matter and antimatter be present in equal amounts on large scale structure of the universe?

If we believe in baryon number conservation as a universal law. The matter and antimatter must have created in equal amounts during the first few microseconds of big-bang. Therefore the antimatter...

Why Bosons have integer spins?

This might be a very naive question but I really don't have a proper answer. Why Bosons have integer spins while Fermions have half-integer spins?
