1. Supersymmetry and LHC missing energy signals / Carena, Marcela ; Osborne, James ; Shah, Nausheen R. ; Wagner, Carlos E. M.
Current analyses of the LHC data put stringent bounds on strongly interacting supersymmetric particles, restricting the masses of squarks and gluinos to be above the TeV scale. [...]

2. Higgs Pair Production as a Signal of Enhanced Yukawa Couplings / Bauer, Martin ; Carena, Marcela ; Carmona, Adrián
We present a nontrivial correlation between the enhancement of the Higgs-fermion couplings and the Higgs pair production cross section in two Higgs doublet models with a flavor symmetry, with implications for LHC searches. [...]

3. Probing the electroweak phase transition via enhanced di-Higgs boson production / Carena, Marcela ; Liu, Zhen ; Riembau, Marc
We consider a singlet extension of the standard model (SM) with a spontaneous Z2 breaking and study the gluon-gluon fusion production of the heavy scalar, with subsequent decay into a pair of SM-like Higgs bosons. [...]

4. Higgs portals for thermal Dark Matter. EFT perspectives and the NMSSM / Baum, Sebastian ; Carena, Marcela ; Shah, Nausheen ; Wagner, Carlos
We analyze a low energy effective model of Dark Matter in which the thermal relic density is provided by a singlet Majorana fermion which interacts with the Higgs fields via higher dimensional operators. [...]

5. Challenges and opportunities for heavy scalar searches in the t t ¯ $$ t\overline{t} $$ channel at the LHC / Carena, Marcela ; Liu, Zhen
Heavy scalar and pseudoscalar resonance searches through the gg → S → t t ¯ $$ gg\to S\to t\overline{t} $$ process are challenging due to the peculiar behavior of the large interference effects with the standard model t t ¯ $$ t\overline{t} $$ background. [...]

6. Flavor from the electroweak scale / Bauer, Martin ; Carena, Marcela ; Gemmler, Katrin
We discuss the possibility that flavor hierarchies arise from the electroweak scale in a two Higgs doublet model, in which the two Higgs doublets jointly act as the flavon. [...]

7. Higgs production and decay in models of a warped extra dimension with a bulk Higgs / Archer, Paul ; Carena, Marcela ; Carmona, Adrian ; Neubert, Matthias
Warped extra-dimension models in which the Higgs boson is allowed to propagate in the bulk of a compact AdS 5 space are conjectured to be dual to models featuring a partially composite Higgs boson. [...]

8. Light dark matter, naturalness, and the radiative origin of the electroweak scale / Altmannshofer, Wolfgang ; Bardeen, William ; Bauer, Martin ; Carena, Marcela ; et al
We study classically scale invariant models in which the Standard Model Higgs mass term is replaced in the Lagrangian by a Higgs portal coupling to a complex scalar field of a dark sector. [...]

9. Minimal composite Higgs models at the LHC / Marcela Carena ; Leandro Da Rold ; Eduardo Pontón
We consider composite Higgs models where the Higgs is a pseudo-Nambu Goldstone boson arising from the spontaneous breaking of an approximate global symmetry by some underlying strong dynamics. [...]

10. Impersonating the Standard Model Higgs boson: alignment without decoupling / Marcela Carena ; Ian Low ; Nausheen R. Shah ; Carlos E.M. Wagner
In models with an extended Higgs sector there exists an alignment limit, in which the lightest CP-even Higgs boson mimics the Standard Model Higgs. [...]
