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
Higgs effective theory	An add-on for the SM implementation containing the dimension 5 gluon fusion operator.	C. Duhr	Available
4th generation model	A fourth generation model including a t' and a b'	C. Duhr	Available
Standard model + Scalars	The SM, together with a set of singlet scalar particles coupling only to the SM Higgs, and allowing it to decay invisibly into this new scalar sector.	C. Duhr	Available
Hidden Abelian Higgs Model	A Z' model where the Z' interacts with the SM through mixings, leading to very small non-SM like Z' couplings.	C. Duhr	Available
Hill Model	A model with an unusual extension of the SM Higgs sector.	P. de Aquino, C. Duhr	Available
The general 2HDM	The most general 2HDM, including all flavor violation and mixing terms.	C. Duhr, M. Herquet	Available
Triplet diquarks	The SM plus triplet diquark scalars.	J. Alwall, C. Duhr	Available
Sextet diquarks	The SM plus sextet diquark scalars.	J. Alwall, C. Duhr	Available
Monotops	The SM plus monotop effective Lagrangian.	B. Fuks	In construction
Type III See-Saw Model	The SM, including neutrino masses coming from a type III See-Saw mechanism.	C. Biggio, F. Bonnet	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	Not Available
