LHC signals of triplet scalars as dark matter portal: cut-based approach and improvement with gradient boosting and neural networks
Atri Dey, Jayita Lahiri, Biswarup Mukhopadhyaya
We consider a scenario where an SU(2) triplet scalar acts as the portal for a scalar dark matter particle. We identify regions of the parameter space, where such a triplet coexists…

LHC signals of a heavy doublet Higgs as dark matter portal: cut-based approach and improvement with gradient boosting and neural networks
Atri Dey, Jayita Lahiri, Biswarup Mukhopadhyaya
Though the 125-GeV scalar, as the Higgs boson of the standard model, is disfavoured as a dark matter portal by direct searches and the observations on relic density, a heavier scal…

Extended scalar sectors, effective operators and observed data
Atri Dey, Jayita Lahiri, Biswarup Mukhopadhyaya
The available data on the 125 GeV scalar is analysed to explore the room for new physics in the electroweak symmetry breaking sector. The first part of the study is model-indep…
