Update on scalar singlet dark matter
One of the simplest models of dark matter is where a scalar singlet field S comprises some
or all of the dark matter and interacts with the standard model through an| H| 2 S 2 coupling …

Direct detection of Higgs–portal dark matter at the LHC
We consider the process in which a Higgs particle is produced in association with jets and
show that monojet searches at the LHC already provide interesting constraints on the …
