The lowest order contribution to the electron mass shift for a one mode squeezed vacuum state is given by $δm(Ω,s)/m=α(2/π)(Ω/m)^2\sinh^2(s)$, where $Ω$ and $s$ stand for the mode frequency and the squeeze parameter and $α$ for the fine structure constant, respectively. The correction to the anomalous magnetic moment of the electron is $δa_e(s)=-(4α/π)\sinh^2(s)$.4 p., latex-article style, TUW-preprintHigh Energy Physics - Phenomenologytext
