13. Extending 2HDM by a singlet scalar field - the case for dark matter

Bohdan Grzadkowski (University of Warsaw)

We extend the two-Higgs doublet models of Type I and Type II by adding a real gauge-singlet scalar $S$ which is the Dark Matter (DM) candidate (2HDMS models). We impose theoretical constraints derived from perturbativity, stability, unitarity and correct electroweak symmetry breaking and require that the lightest CP-even Higgs, $h$, fit the LHC data for the $\sim 125.5$ GeV state at the...

9. Scalar dark matter and possible implications at the LHC

Prof. Per Osland (University of Bergen (NO))

I shall review an extension of the Inert Dark Matter model, that also allows for CP violation in the scalar sector. This kind of model contains charged scalars that could be produced at the LHC, and emit SM particles via virtual W or Z emission in its decay to dark matter.

7. Three Higgs doublet models with S3 symmetry and dark matter candidates

Margarida Nesbitt Rebelo (Instituto Superior Tecnico (IST))

I shall report on work in progress in the framework of three Higgs doublets with an S3 symmetry providing a dark matter candidate. This is still very preliminary and I shall focus on the main questions we want to address.

11. Search for Scalar Charm Pair Production with the ATLAS Detector in pp Collisions at sqrt(s) = 8 TeV

William Kalderon (University of Oxford (GB))

Supersymmetry (SUSY) is a theoretically attractive extension to the Standard Model of particle physics with the potential to solve several of its theoretical problems. For instance, the nature and production of dark matter is explained in SUSY by the existence of new stable, weakly interacting particles. A search for the production of supersymmetric partners of the charm quark will be...
