Abstract
A search for new physics is performed using events having large missing transverse momentum and one or more jets with high transverse momenta in a data sample of proton-proton interactions at the centre-of-mass energy of 13 TeV. The data correspond to an integrated luminosity of 2.3 fb-1 collected in 2015 by the CMS detector, during the Run2 of the LHC. Results are presented in terms of limits on dark matter production based on simplified models.

Highlights
Many theories predict the existence of Dark Matter (DM) particles interacting with Standard Model (SM) particles via bosonic mediators
The DM signal is extracted from the ETmiss distribution using a shape-based method
The data are consistent with the SM expectation as can be seen from the ETmiss distribution on figure 5
Summary
Many theories predict the existence of Dark Matter (DM) particles interacting with Standard Model (SM) particles via bosonic mediators. This means DM could be produced at the LHC in proton-proton collisions. As DM particles would escape the detector without interacting, additional objects need to be produced along with the DM, this can be realized by initial state radiation (ISR, see figure 1). ISR of a gluon or a vector boson would result in spectacular events where at least one jet balances large missing transverse energy (ETmiss). In this poster proceedings, we will focus on gluon emission: these events are known as monojet events. Reference [2] is the standard reference for the CMS detector
