Scalar Lie point symmetries of the Standard Model with one or two real gauge singlets
M. Aa. Solberg
We present a classification of all scalar Lie point symmetries of the Standard Model with one or two real gauge-singlet scalars (SM+S and SM+2S). By analyzing the associated field…

Lie symmetry analysis of the two-Higgs-doublet model field equations
M. Aa. Solberg
We apply Lie symmetry analysis of partial differential equations (PDEs) to the Euler-Lagrange equations of the two-Higgs-doublet model (2HDM), to determine its scalar Lie point sym…
