Comparative Study of Magnetic Moment of Leptons in Hot and Dense Media
Samina Masood, Holly Mein
We study the magnetic moment of leptons in extremely hot universe and superdense media of stars at high temperatures. Anomalous magnetic moment of charged leptons is inversely prop…

Samina Masood
It is known that the finite temperature and density (FTD) corrections increase the electron mass, charge and modify the properties of the emitted radiation. All the signals, travel…
