Simple extensions of the SM

This is a collection of models that are simple bottom-up extensions of the SM, obtained by adding a set of new particles and or interations to the Standard Model.

Available models

Model	Short Description	Contact	Status
Axigluon model	The SM plus a scalar gluon field.	S. Krastanov	Available
DY SM extension	The SM plus new spin-0, -1, and -2 bosons that contribute to Drell-Yan production of leptons at the LHC.	N. Christensen	Available

Hill Model	A model with an unusual extension of the SM Higgs sector.	P. de Aquino, C. Duhr	Available
Inert Doublet Model	A model with an additional complex scalar SU(2)L doublet and an unbroken Z2 symmetry under which all SM particles are even while the extra doublet is odd.	A. Goudelis, B. Herrmann, O. Stal	Available
